The development of catalysts has seen tremendous growth recently but most strategies only report utilization of catalysts for a few initial cycles without taking into account the influence of oxygen poisoning. Here, the magnetic Fe3O4@EDTA-Fe (MEFe, having a core Fe3O4 particle with EDTA-Fe coating) was investigated as a model catalyst for long-term recycling for the removal of nitrogen oxide (NOx) from NO/O2 mixture, followed by N2O recovery. The concentration of oxygen in the flue gas was found to have a strong impact on NOx absorption and catalytic response. To circumvent the oxygen poisoning, the MEFe was subjected to electrochemical treatment in the presence of neutral red (N.R.) and NO removal efficiency was ∼95 % noted. Furthermore, the surface of the catalyst degraded significantly (p < 0.05) after 6-7 repetitive cycling due to surface catalytic reactions, surface poisoning, oxidation of metallic species as well as residual stresses. The MEFe surface was reconstructed after 7 cycles using EDTA solution and Fe source to achieve similar surface coating as the fresh MEFe catalyst. The reconstructed MEFe exhibited similar NOx absorption capability as the fresh MEFe and the reconstruction loop was repeated several times to achieve long term cycling, which make the catalyst cost-effective. Hence, it is proposed that a successful regeneration process can be employed for promising, sustainable and long-lasting catalytic treatment of air pollutants.

The present study focused on the use of sewage sludge (SS) as a casing material amendment and the potential uptake of metal elements by the cultivated white button (Agaricus bisporus: MS-39) mushroom. Laboratory experiments were performed under controlled environmental conditions to grow A. bisporus on the composted wheat straw substrate for 50 days. Different treatments (0, 50, 100, 150, and 200 g/kg) of casing material were prepared by mixing garden and dried SS and applied on the mushroom substrate after proper sterilization. The results revealed that SS application was significant (p < 0.05) in accelerating mushroom yield with a biological efficiency of 65.02% for the mixing rate of 200 g/kg. Moreover, the maximum bioaccumulation of selected metal elements (Cu, Cr, Cd, Fe, Mn, and Zn) was observed using the same treatment. Additionally, the multiple regression models constructed for the uptake prediction of metal elements showed an acceptable coefficient of determination (R2 ...

The increasing levels of nitrogen oxyanion pollution especially nitrate in water environments have become a critical issues of concern because of the potential risk on ecology and human health. Owing to its distinctive merits of sustainability, lesser operational and maintenance expenditure, the utilization of constructed wetland systems for the treatment of wastewater has turned out to be predominant worldwide. Its nitrogen oxyanion removal performance has received significant attention in the last two decades. This chapter presents a comprehensive outline of the application of constructed wetlands (CW) for nitrogen oxyanion removal from water and wastewater. The removal mechanisms and transformations of nitrogen are also discussed. In addition, the major factors that influence the removal performances in CWs are elucidated, especially the types of carbon sources commonly used, and how it affects the denitrification process. This chapter would be useful to engineers and researchers in the field of water and wastewater engineering.

The continuous degradation of environmental ecosystems (land, water and soil) resulting from crude oil exploration and exploitation activities continues to gain global attention. This study investigates the effects of crude oil exploration and exploitation activities on soil, water and air in the study area. Soil samples were collected in three replicates at depths of 0–15 and 15–30 cm at sampling distances of 20, 100 and 200 m a from core oil exploitation operation area and a control point. Water samples were also taken from within the study area and analyzed using standard procedures. Major pollutants concentrations of particulate matter (PM2.5 and PM10) of the air were also measured using Air Quality Index (AQI). The results reveal that the soil, water and air parameters measured mostly at 20 m from the core oil operation area compromise the allowable standards provided for healthy living. In the same manner, some results at 100 and 200 m were slightly higher than the recommended values in some cases of
heavy metals and bacteria activities in the soil. The AQI at 20 m was far above the permissible limit provided by the Environmental Protection Agency while others are gradually drawing towards the limit given for each pollutant. To safeguard the health of the residents of the host community and oil field workers, there is a need for proper and frequent environmental monitoring and assessment by authorized regulatory bodies in Nigeria. This will prevent any future exposure which may endanger the lives of the dwellers.

Biochar was utilized to intensify constructed wetland (CW) for further organic and nitrogen removal from secondary wastewater. Four sets of non-aerated biochar amended vertical flow CW (VFCW) were developed to investigate the synergistic effects of biochar and microbes on pollutant removal. Results showed that the average COD and nitrogen removal efficiencies of VFCW1 (with 1% w/w biochar with microbe and plants) achieved 89.1±5.6% and 90.2±3.1% respectively, and their corresponding removal rates of 10.2±0.8 mg-COD/(m3.d) and 3.57±0.3 mg-TN/(m3.d) which were 35 and 52.3% higher than control. The biochar’s dissolved organic carbon release in VFCWs indicated that water and acidic media portray the optimum conditions for nitrogen removal. The 16S RNA gene sequencing analysis indicated that in the biochar-amended VFCWs, bacterial phylum Proteobacteria (24.13-51.95%) followed by Chloroflexi (5.64-25.01%), Planctomycetes (8.48-14.43%), Acidobacteria (2.29-11.65%) were abundantly enhanced. Conclusively, incorporating biochar in non-aerated VFCWs is an efficient technique for enhancing nitrogen removal from secondary effluent.

Available freshwater scarcity significantly affects sustainable food production for the rapidly growing population. This problem has forced people in most parts of the world to use wastewater as a viable solution. However, wastewater reuse has some deleterious effects on human and environmental health. This study was designed to investigate the health risks (HRs) of heavy metals (HMs) from vegetables irrigated with untreated and treated wastewater. The composite wastewater was collected at various sites in Arba Minch town and subjected to aerobic-anoxic treatment. Treated and untreated wastewater (UTW) was used to irrigate vegetables (lettuce, cabbage and tomato), and HM results were compared with the control (tap water) and standards. Water, soil and vegetables were investigated for various physical and chemical properties. Human health effects due to vegetable consumption were analyzed using HR-index (HRI), target hazard quotient (THQ) and hazard index (HI). The results revealed that most of the water quality indexes were significantly enhanced after aerobic-anoxic treatment, suggesting that wastewater collected from different sites was suitable for biodegradation. Soil physi-cochemical analyses also showed that pH, cation exchange capacity, organic carbon and organic matter were higher for UTW irrigated soil. Heavy metal concentrations were relatively greater in soils than water used for irrigation purposes and vegetables. The HM concentration in vegetables was higher for UTW than for treated and tap water irrigated vegetables. In vegetables, the order of HM content was Fe > Mn > Zn > Pb > Cu > Cd. Tomato followed by cabbage and lettuce accumulated significant amount of HMs (Fe > Mn > Zn > Pb > Cu > Cd) in their different organs (fruit/leaf>root>stem). The individual and combined health indexes (HRI, THQ and HI) showed Science of the Total Environment xxx (xxxx) xxx ⁎ Correspondence to: A. Guadie,

Environmental pollution is increasingly becoming an issue of significant public interest in many developing countries and the international community at large. The growing socioeconomic developments as witnessed globally in recent times due to rapid urbanization and industrialization have led to the overexploitation of natural resources, while inadvertently resulted in severe environmental problems. In this chapter, we attempted to present the effect of environmental pollution to our physical environment as well as its socioeconomic impacts. Specifically, we focused more on the major types of pollution, which are widely recognized as international public health problems, namely, land/soil, water, air, noise, and plastic/microplastic pollution, enumerating their effects and how they have acted as an obstruction to the social and economic progress by placing tremendous pressure on resources and environment. Possible ways of ensuring environmental quality and sustainability leading to improved public health and well-being alongside with different kinds of intervention were proposed.

Pollutants in aquatic environment tends to alter the community composition and activities of biofilm cells. The stress induced by these pollutants leads to the production of excessive reactive oxygen species (ROS) which play a key role in the degradation of pollutants in aquatic environment. This mini-review is aimed at forecasting the efficiency of the use of natural freshwater microalgae biofilm in the treatment of water resulting from mining activities. Moreover, it summarises the concept of mining by concisely stating the stages involved in mining and how the pollutants produced during mining can cause deleterious effects to aquatic flora and fauna. Environmental issues resulting from mining activities and how they hindered the progress of biodiversity were concisely discussed. Freshwater microalgae play an important role in the mitigation of the impact of pollution resulting from mining activities. The process of pollutants removal in freshwater by microalgae biofilm is by degradation and biosorption. However, it is an unestablished fact that the extracellular polymeric substances (EPS) were responsible for the biosorption of heavy metals from mining wastewater. It is also important to know the kinetic model that best explains the chemical and physical reactions of heavy metal absorption by the surface of microalgae biofilm.

This study investigated the potential of Moringa oleifera (MO) seed biomass as a coagulant for the removal of turbidity, biochemical oxygen demand (BOD), and chemical oxygen demand (COD) of municipal wastewater. Triplicated laboratory experiments using MO coagulant added at varying treatment dosages of 50, 100, 150, 200 mg/L, and a control (0 mg/L) treatment were performed for a settling period of 250 min at room temperature. Kinetics and prediction variables of cumulative turbidity, BOD, and COD removal were estimated using simplified first order and modified Gompertz models. Results showed that the maximum removal of turbidity, BOD, and COD were 94.44%, 68.72%, and 57.61%, respectively, using an MO dose of 150 mg/L. Various kinetic parameters, such as rate constant (r), measured (RE m) versus predicted (RE p) cumulative removal, and specific pollutant removal rate (µ m), were also maximum when an MO dose of 150 mg/L was added, the standard error being below 5%. The developed models were successfully validated over multiple observations. This study suggests low cost and sustainable removal of turbidity, BOD, and COD of municipal wastewater using MO seed biomass as a coagulant.

Water is an essential resource required for various human activities such as drinking, cooking, and other recreational activities. While developed nations have made significant improvement in providing adequate quality water and sanitation devoid of virus contaminations to a significant percentage of the residences, many of the developing countries are still lacking in these regards, leading to many death cases among the vulnerable due to ingestion of virus-contaminated water and other waterborne pathogens. However, the recent global pandemic of COVID-19 seems to have changed the paradigm by reawakening the importance of water quality and sanitation, and focusing more attention on the pervasive effect of the use of virus-contaminated water as it can be a potential driver for the spread of the virus and other waterborne diseases, especially in developing nations that are characterized by low socioeconomic development. Therefore, this review assessed the socioeconomic inequalities related to the usage of virus-contaminated water and other waterborne pathogens in developing countries. The socioeconomic factors attributed to the various waterborne diseases due to the use of virus-contaminated water in many developing countries are poverty, the standard of living, access to health care facilities, age, gender, and level of education. Some mitigation strategies to address the viral contamination of water sources are therefore proposed, while future scope and recommendations on tackling the essential issues related to socioeconomic inequality in developing nations are highlighted.

This study examines the influence of uncontrolled deposition of MSW disposal on soil in four selected dumpsites across Akure city, Nigeria. Physicochemical and microbial tests were carried out using standard procedure. Soil samples were randomly collected using soil auger from the major (Igbatoro and Iju-Itaogbolu), and the minor (Ijare and FUTA) dumpsites, at depths (0–10, 10–20, 20–30 cm), with control samples taken at a distance 20 m away from each dumpsite. The physicochemical parameters measured include
pH, total organic matter, total organic carbon and particle size distribution. The results showed that samples were predominantly acidic (4.12 to 6.73), sandy (32.69 to 65.40) with values ranging from 0.17 to 4.14 and 0.02 to 3.15 for organic matter and organic carbon respectively. The mean values for both aerobic bacterial counts and heterotrophic fungal counts from control to the dumpsites ranged from 188 × 106 to 258 × 106 cfu/mL, and 128 × 106 to 193 × 106 cfu/mL, respectively. Although there exists some positive impacts of dumpings on soil, their adverse effects are life threatening.

In this communication, we proposed sustainable preventive measures that may be adopted by the low-income countries to forestall the potential outbreak and transmission of COVID-19 (coronavirus disease 2019) through wastewater. Most low-income countries have poor sanitation and wastewater management policies, which create potential risks of COVID 19 spread. Hence, the proposed measures include decentralization of wastewater treatment facilities, community-wide monitoring and testing of SARS-CoV-2 in wastewater samples, improved
sanitation, developing point-of-use devices for wastewater decontamination, and more focused policy interventions. Therefore, this paper adds useful insights into the monitoring and management of ongoing COVID-19 outbreak in low-income countries.

Soil erosion and mass movement processes spread across Anambra State in Nigeria, therefore making management and conservation techniques expensive and difficult in execution across the entire state. This study employed the Revised Universal Soil Loss Equation (RUSLE) model with the integration of geographic information system (GIS) and remote sensing techniques to assess the risk of soil erosion and hotspots in the area. Remotely sensed data such as Landsat 8 imagery, Shuttle Radar Topography Mission (SRTM) imagery, Era-Interim coupled with world soil database were used as digital data sources for land use map, digital elevation model, rainfall and soil data, respectively, to generate the Universal Soil Loss Equation (USLE) parameters. The results indicated vulnerability level in low, medium and high cover areas of 4,143.62 (91%), 332.29 (7%) and 84.06 (2%) km 2 , respectively, with a total soil loss between 0 and 181.237 ton/ha/yr (metric ton per hectare per year). This study revealed that high rainfall erosivity, steep and long slopes, and low vegetation cover were the main factors promoting soil loss in the area. Thus, the amount of soil loss in Anambra State is expected to increase with climate change and anthropogenic activities.

Water is an essential natural resource that is vital for sustaining every form of life existence. Availability of groundwater is spatially and temporally dependent upon the terrain of an area. In order to improve efficiency and effectiveness in water availability, supply and use, the construction of water harvesting structures across streams/watersheds is gaining drive in recent years. The increase in demand for water has led to the construction of water storage dams for various purposes such as community and industrial use, irrigation, flood control, hydropower and river canalization. Safety is the key consideration than cost and capacity as the failure of a dam often results to severe loss of lives and properties, hence the need to consider some important criteria for suitable dam siting. In this study, potential sites for construction of dams in Imo State, Nigeria, have been identified by using geographical information system and remote sensing techniques which were integrated with fuzzy logic to achieve the study objectives. Climatic and geophysical factors such as rainfall, runoff, stream order, soil type, geology type and land use were considered. These factors assigned fuzzy membership classes according to their contribution in locating suitable dam sites. The fuzzy members for all the factors were combined using the fuzzy overlay technique to produce the suitable dam site selection map. Majority of the selected sites were located in the northwestern part of Imo State which is characterized by high elevation and gentle slope.

We analyze with four compartments a deterministic nonlinear mathematical model of typhoid fever transmission dynamics. Using the Lipchitz condition, we verified the existence and uniqueness of the model solutions to establish the validity of the model and derive the equilibria states of the model that is, disease-free equilibrium (DFE) and endemic equilibrium (EE). The computed basic reproductive number R0 was used to establish that the disease-free equilibrium is globally asymptotically stable when its numerical value is less than one, the disease will be under control. In addition, the Lyapunov function was applied to investigate the stability property for the (DFE). The model was numerically simulated to validate the results of the analysis.

Polycyclic aromatic hydrocarbons (PAHs) are regarded as priority pollutants owing to their toxic, mutagenic and carcinogenic characteristics. Perylene is a kind of 5-ring PAH with biological toxicity, and classified as a class III carcinogen by the World Health Organization (WHO). Nowadays, some of its derivatives are often used as industrial pigments. Hence, urgent attention is highly needed to develop new and improved techniques for PAHs and their derivatives removal from the environment. In this study, Fenton oxidation process was hybridized with
the biological (anaerobic and aerobic) treatments for the removal of perylene pigment from wastewater. The experiments were carried out by setting Fenton treatment system before and between the biological treatments. The biological results showed that COD removal efficiency reached 60% during 24 h HRT with an effluent COD concentration of 1567.78 mg/L. After the HRT increased to 48 h, the COD removal efficiency was slightlyincreased (67.9%). However, after combining Fenton treatment with biological treatment (Anaerobic-Fenton-
Aerobic), the results revealed over 85% COD removal efficiency and the effluent concentration less than 600 mg/L which was selected as the better treatment configuration for the biological and chemical combined system. The microbial community analysis of activated sludge was carried out with high-throughput Illumina sequencing platform and results showed that Pseudomonas, Citrobacter and Methylocapsa were found to be the dominant genera detected in aerobic and anaerobic reactors. These dominant bacteria depicted that the community
composition of the reactors for treating perylene pigments wastewater were similar to that of the soil contaminated by PAHs and the activated sludge from treating PAHs wastewater. Economic analysis results revealed that the reagent cost was relatively cheap, amounting to 10.64 yuan per kilogram COD. This study vividly demonstrated that combining Fenton treatment with biological treatment was efficient and cost-effective.

Public places within Nigeria are ever humming with tremendous activity and accordingly reflecting growth and development of the host cities. The ensuing channelization demands of these centres calls for apposite sanitation to enhancing efficient operation and utilization. This study was undertaken to assess the present status of onsite sanitation facilities in public places within Akure, to trace problems related to sanitation and solid waste management. Logical sampling methods were used to sample the users and passers-by of selected public places. Primary data were acquired from scrutinizing sanitation facilities, employing questionnaire, and interviewing the chief players-drivers and traders-in these centres. Qualitative and quantitative data obtained from both primary and secondary sources were employed for this study. Survey facts were analyzed using descriptive statistical method while Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was further utilized in results analysis. The outcomes showed existing sanitary facilities are insufficient to match the populace, and a poor maintenance of these facilitates credited to unavailability of dedicated management staff coupled with flawed maintenance and monitoring by local authorities. This is occasioned by lower than normal patronage. Further, the general experience of the respondent with regard to these facilities were rather unpleasant. Combating strategies to the established challenges in the selected centres are active governmental involvement in restructuring these places in conformity with standard requirements; community support programs, and a supervisory team routinely overseeing the reliability and development of sanitation facilities.

Production of quality and safe potable water is vital to human health. This research examined the pota-bility of the packaged sachet water being marketed within the Federal University of Agriculture, Abeokuta (FUNAAB) campus. Seven sachet water brands were purchased randomly and the physico-chemical and bacteriological qualities were determined. The results acquired are as follows: pH, 6.57-6.79 ± 0.02; electrical conductivity (EC), 0-145.00 ± 5.00 lScm À1 , turbidity, 0.00-0.59 ± 0.02 NTU; total dissolved solids (TDS) 0.00-70.00 ± 0.00 mg/L; total suspended solids (TSS), 0.00-0.01 ± 0.00 mg/L; calcium , 42.00-161.00 ± 1.00 mg/L; iron, 0.65-1.25 ± 0.05 mg/L; alkalinity, 0.65-1.25 ± 0.05 mg/L; sulphate, 0.95-33.71 ± 0.01 mg/L; and nitrate, 0.01-0.04 ± 0.00 mg/L. Magnesium and phosphate were below detection level. The odour and taste were also unobjectionable. The physicochemical test results conformed with the World Health Organization World Health Organisation (WHO) (2004) and Nigerian Standard for Drinking Water Quality (NSDWQ) standards for drinking water. However, bacteriological analysis established the presence of total bacteria count in all water samples (100%) while two brands, (sample C and G), of the packaged sachet water (28.57%) were contaminated with total coliforms which failed to comply with WHO and NSDWQ standard. The analysed physicochemical and bacteriological parameters of the water samples exhibited significant differences (P < 0.05). Sustainable measures such as scientific examination of the water quality during preproduction, production and postproduction stages to determine the means of access of contaminants as its directly affect public health and safely should be routinely performed by the water producers. The National Agency for Food and Drug Administration and Control should implement established regulations and execute their statutory responsibilities through routine checks and effective monitoring of the operation and production facilities. Furthermore, Standard Organisation of Nigeria should intensify its effort through restrictions of the manufacturers using substandard packaging materials for their production. Consequently, there is need to invest in sustainable water infrastructure (water supply systems, treatment plants, storage and water resource management) that will cater for the populace of the entire university community through partnership with relevant stakeholders in the water industry and donations from non-governmental, national and international organizations hence, reducing the dependence on water supply from substandard private vendors.

Recent happenings (like fire outbreak and soil contamination) on Nigerian dumpsites had reiterated the need to frequently monitor and assess these dumpsites in order to avert environmental disaster. This study was conducted to determine the concentration and distribution of elements in four selected dumpsites in Ondo State, Nigeria. Soils sampled from the dumpsite were tested for their particle size distribution, cation exchange capacity and elemental concentration. The statistical relationship between the elements present was also carried out by analyzing its concentrations. The results showed that sand and clay were the main particles present in the studied dumpsite soils. The low cation exchange capacity values of the soil from the studied dumpsite showed its low retention capacity and fertility. The elements (calcium, magnesium, potassium) needed as macronutrients for plant growth on the dumpsite soil were not present in a large concentration which may be due to the low nutrient retention capacity of the soil. The heavy metals present in the dumpsite though above recommended permissible limit (with the exception of chromium) showed (through the contamination indices) no immediate risk on man and the environment. Statistical analysis showed that there was a statistically significant difference in the concentration of the elements present on the studied dumpsite soils. There was, however, no statistically significant difference in the studied dumpsites. Whatever future plans the State government may have for these dumpsites, this study had pointed out some areas of the soil that may need to be improved and/or monitored for proper remediation.

This study investigates the production of ceramic water filters from various clay materials and their performances to improve the physical and bacteriological quality of drinking water. Ceramic water filters were prepared by combining clay with sawdust at various ratios. The water absorption rate, flow rate and microbial removal efficiency were analyzed. The results indicated that some clays produced from Ire Ekiti Brown clay at ratio 50:50 and 40:60, Ire Ekiti Red clay at ratio 40:60 and 30:70 and Isan Ekiti Brown clay at ratio 40:60 and 30:70 all have high absorption rates which resulted from the high sawdust content in the mixture; as sawdust possesses high porosity. Also, filters produced ranging from 60:40 to 40:60, 50:50 to 40:60 and 70:30 to 40:60 for Ire Ekiti brown clay sample, Ire Ekiti red clay sample and Igbara Odo Ekiti clay sample respectively and for both Ikere Ekiti white clay and Ara Ekiti clay samples at 40:60 all showed better microbial removal efficiency as they could remove more than 95% of coliform bacteria and Escherichia coli. The Ire Ek-iti Brown ceramics filter was considered suitable for producing filter materials based on a recipe combination which varies from 60:40-40:60. Ire Ekiti Red and Igbara Odo Ekiti Brown ceramics pot filters both recorded a high flow rate owing to the high porosity of their filter components which is as a result of the higher percentage of the constituents of burnout material. Of all the ceramic filter produced, 50% to 50% ratio of Igbara odo clay to sawdust gave the best and optimum mix which was found to be highly efficient in the removal of microbes in the water sampled. This research reveals the ability of the ceramic filters made principally from locally available materials (clay and sawdust) for microbial removal in wastewater biotreatment.

The acute shortage and scarcity of lands for suitable waste disposal is rapidly becoming a critical growing potential problem in most urban cities in developing countries of the world, and several fast-growing cities in Nigeria are not exempted from this menace. In this study, geographic information system (GIS) and analytic hierarchy process (AHP) are combined to select the most suitable landfill location in Lokoja, Nigeria. The landfill site selection criteria considered include proximity to major road, powerline, water body, landfill areas and built-up area. GIS was used to digitize spatial features related to unsuitable landfill site. A total of 19 candidate landfill sites were identified from GIS analysis. AHP model was developed from the GIS result as multi-criteria decision tool in evaluating each candidate site so as to choose the best appropriate landfill site. AHP model rated candidate site 11 located along Jimgbe road has the most preferable site to locate a landfill in Lokoja with an approximate area of 3.4204 km2; the distance from the minor road, nearest water body, powerline and built-up areas to the location is 210.50 m, 1408.20 m, 1810.80 m and 205.61 m, respectively. Also, the model rated candidate site 16 located along 500 housing units as the least preferable site to locate a landfill in Lokoja. The characteristic features of the site location as obtained from GIS analysis include an approximate area of 2.5680 km2 at an approximate distance of 2430.75 m, 594.04 m, 1980 m and 200.68 m from the major road, water body, powerline and built-up areas, respectively. This result will greatly serve as guide in landfill site selection in major urban states of other developing countries.

Population explosion coupled with poor governance and land use planning is responsible for indiscriminate dumping of solid waste in unsuitable sites. Despite the vast availability of modern methods of siting landfills, many waste disposal methods in Akure are piled up in open sites and unsafe. Owing to this lack of effectiveness of these common methods in Akure, a better approach is adopted to enable the analysis of a number of required qualitative and quantitative issues for landfill site selection. This study is aimed at identifying suitable sites for
solid waste disposal and management while considering all essential factors and rating criteria by integrating GIS with multi-criteria decision analysis (MCDA) in Akure, Ondo State. Standards for siting landfill formulated by the Environment Protection Agency (EPA) were employed in this study. The criteria that are considered herein are land use, slope, distance to drainage, distance to linear features, soil, geology, distance to the residence and road accessibility. These criteria were assigned fuzzy membership classes based on their importance in siting landfill. The fuzzy members of all criteria were overlaid to generate the final landfill site suitability map which was classified into five: not suitable (34.1%), less suitable (50.4%), moderately suitable (0.3%), suitable (0.02%) and highly suitable (15.5%). The Analytical Hierarchy Process (AHP) technique was employed in the selection of the landfill site with reverence to multiple criteria and the fuzzy membership classes in accordance with the standards of the EPA. The result of this study serves as guide for further field survey.

The efficacy of the Moringa oleifera (MO) in wastewater treatment has been well studied and documented. However, there exists a significant gap in exploring the operating conditions to optimize the wastewater treatment process. This study investigated and optimized the removal efficiency of turbidity, biochemical oxygen demand (BOD), and chemical oxygen demand (COD) from municipal wastewater under the operating conditions of pH (5–7), MO dosage (50–200 mg/L), and settling time courses (60–240 min) using face-centered central composite design (FCCCD) of response surface methodology. The experimental results of FCCCD were fitted to the second-order quadratic model to approximate the effects of each variable factor and their interactions on the responses of interest in a mathematical relationship and consequently, predict the process responses. The obtained results revealed that under the optimum operating conditions of pH, MO dosage, and settling time
of 6.01, 182.74 mg/L, and 228.08 min, respectively, the predicted values of turbidity, BOD, and COD removal efficiencies were 98.20%, 92.96%, and 78.82%, respectively, with the desirability of 1.000. This study demonstrated the effectiveness of FCCCD with a desirability function to optimize the process conditions (pH, MO dosage, and settling time) of coagulation for the turbidity, BOD, and COD removal efficiencies.

A comprehensive understanding of wastewater characteristics is vital in the design and operation of collection, treatment, and disposal facilities and the engineering management of environmental quality. Municipal wastewater generated from the Federal University of Technology, Akure and discharged untreated was determined for feasible irrigation reuse. In this study, physicochemical (odour, temperature, turbidity, total dissolved solids, suspended solids, total hardness, pH, alkalinity, chlorides, nitrates, and phosphates) and bacteriological parameters (total bacterial count and total coliform) of wastewater were examined. The maximum value (1408 mg/L) of the total dissolved solids was found in the sample collected from Akindeko hall in the evening and the pH values ranges between 7.09 and 8.41. Maximum nitrate is 58.2 mg/L in the sample
collected from Abiola hostel, phosphate is 43.4 mg/L in Akindeko hostel, and chloride is 243.2 mg/L in Abiola hostel. The total bacterial count and total coliform count range from 93.67 to 148.33 mg/L and 115.33 to 136 mg/L. The findings of the study conclude that the wastewater quality of the university’s halls of residence was above the standard value of the
United States Environmental Protection Agency guidelines for irrigation reuse when compared. This implies that its usage for irrigation without treatment should be prohibited, since it adversely affects the soil’s properties and releases hazardous substances to the environment. It is, therefore, recommended that a sustainable treatment system be provided to adequately treat all wastewater generated from the university and prevent extra expenses for soil treatment while reutilize for irrigation to supplement natural rainfall for agricultural purposes.

The research was aimed at producing a cost-effective ceramic filter for the removal of bacteria in wastewater using locally sourced materials. Clay from several locations in Ekiti state, Nigeria was mixed with sawdust (combustible material) to form a ceramic filter. The results showed that the 50%-50% ratio of Igbara odo clay to sawdust was the most effective and optimum mix. This was in terms of a flow rate of 1.9 L/hour, removal effi-ciencies of 80% and 100% for coliform and E. coli bacteria respectively. Introduction Ceramic materials based on clay have been used in different parts of the world as a means of purifying and storing water at points of use. The application of ceramic filter isn't solely a brand new and trendy technique , but it reduces cost and the use of chemicals/coagulants in water treatment. The use of clay and sawdust from southwest Nigeria is worth researching upon for use as ceramic materials. Nigerian clay soils and sawdust had been used in previous studies for various waste containment purpose [1-3]. Methods Clay soils sampled from different locations (Ara, Igbara Odo, Ikere, Ire and Isan) in Ekiti State, Nigeria were pulverized and sieved through the 0.25 mm sieve size. Sawdust from a hardwood (Nesogordonia papaverifera of Danta Specie) was sieved through the 0.075 mm sieve size. The sieved samples of clay and sawdust were mixed in various ratios with water to form a mouldable paste. These were aged to cause physical changes in the material over time. The aged moulded paste materials firing process was carried out in a traditional kiln (made of low-cost heat resistant brick made of Ball clay, sand and sawdust) after an air drying stage had been completed. The air drying was to prevent material from cracking due to rapid drying or heating during the firing process. Atterberg limit tests [4] were carried out on the clay samples. The ceramic filters were tested for its flow rate and its bacteria removal efficiency. Results and conclusions The Atterberg limits values and colour of the Ekiti clay samples are listed in Table 1. The flow rates were measured based on the reduction in the water column height over a period of time (Table 2). The removal efficiency of Coliform and E. coli from the wastewater was 100% for some of the fabricated ceramic filter samples (Table 3). From the results, Igbara odo clay and sawdust in 50%:50% ratio had the highest performance level in terms of flow rate and bacteria removal efficiency.

As water is a major life sustainer, hence its potability is of great importance in performing that role well. In this study, various water samples were collected within Efon-Alaaye for both physico-chemical and bacteriological tests. A total of nine (9) water samples were taken for analysis with six (6) from various surface sources and three (3) from groundwater sources in the study area. The mean turbidity value, temperature, total dissolved solids (TDS) concentration, hardness and EC are 2.92 NTU, 23°C, 447.8 mg/l, 48.1 mg/l and 138.4 μS/cm respectively. Manganese has mean value of 0.27 mg/l. The concentration of both copper and zinc ranges from 0.07 – 0.13 mg/l and 0.16 – 0.55 mg/l with an average value of 0.04 mg/l and 0.28 mg/l respectively. Water samples collected were also analyzed for total coliform bacteria and ranged from 1 to 4.6/100 ml with an average value of 3.29 colony/100 ml. On the basis of findings, the physico-chemical analysis reveals that some of the water samples were above the WHO standards for parameters like turbidity and TDS while the bacteriological test reveals that seven (7) of the water samples considered met the WHO requirement of portability while the other two samples contain faecal contaminant as E.coli was discovered, though at reasonable rate

Recently, bio-surfactants, like rhamnolipid (RL), have been used as efficient pre-treatments to enhance the accumulation of short-chain fatty acids (SCFAs) from waste activated sludge (WAS). The current study found that SCFA accumulation occurred with evolutional variation in methanogen with RL (0.04 g RL g-1 TSS), resulting in a retarded methane production over a period of 20 days. However, a slow methane production was only detected before the 18th day, while the concentration of acetic acid (HAc) accumulated to a peak at 2616.94 310.77 mg L-1 in the presence of RL, which was 2.58-fold higher than the control assay. During the retarded methane production, the concentration of dissolved hydrogen also increased to 49.27 6.02 mmol L-1, in comparison with 22.45 mmol L-1 of control WAS without RL. According to the analysis of archaea communities induced by RL, hydrogenotrophic methanogens, like Methanobrevibacter, had been substantially promoted at the beginning of quick SCFA and hydrogen production, but their percentage decreased from 70% to 35% with time. Intrinsically, the growth of acetotrophic methanogens were postponed but they contributed most to the methane production in this research according to the correlation analysis.

This study discusses the production of briquettes as an alternative household fuel. Briquettes were produced from sawdust collected from one of the saw-mills in Akure, Ondo State. Water and cow dung were used both as binders in the production. Five briquettes were produced at 100%, 120%, 140%, 160% and 180% weight of water to sawdust while the other five were produced at water to cow dung ratios of 80:20, 60:40, 40:60, 20:80 and 0:100 percentages added to 1.5kg of sawdust. Combustion related properties of the briquettes viz: moisture content, dry density, percentage volatile matter, percentage fixed carbon and heating values were determined. Also, the cost analysis of producing 1000 briquettes was carried out. The results show that briquettes made from sawdust using solely water as binder has good combustion capacity than those produced from sawdust using the mixture of water and cow dung as binders. The cost analysis carried out shows the economic viability of using briquettes as a good substitute of the current ever increasing conventional cooking fuels available. Therefore, the use of wood residues for briquette production will reduce deforestation and environmental degradation by minimizing waste in the sawmill industry

This research compared biogas generated from three different wastes namely poultry waste, cow dung and rabbit waste. Three mini-digesters were locally fabricated to contain each of this waste. The parameters studied are the individual waste biogas yield and the comparative biogas yield from the three wastes. The method of research involved keeping some parameters constant to enhance accurate experimental results. Hence, parameters such as ambient temperature, weight of substrate used and size of digesters were kept constant. The cumulative methane yield for each of the waste was plotted separately and together against the number of days for proper comparison. The results showed that the initial biogas production duration of each of the wastes varies as rabbit wastes yielded almost immediately after 1 day of loading and mixing, poultry took 2 days while cow dung took 4 days. It was also observed that rabbit waste produced the highest volume of methane gas (387 ml), followed by poultry waste (310) ml and cow dung (286 ml). This result was concluded to be such based on the composition of feed taken by the animals which take different time length for microbes to decompose them for biogas production.

Physicochemical analyses were carried out on soil samples from four different waste dumpsites in the Federal University of Technology Akure (FUTA), Nigeria to ascertain the effects of the refuse dumpsites on soil and groundwater qualities. Dumpsite locations are Physics Laboratory (PHY), Post Graduate Hostel (PG), School of Earth and Mineral Science (SEMS) and Staff Quarters (STQ). Soil samples collected at distances 0 (dumpsite), 10 and 20 m intervals away from the dumpsite were analyzed and at depths 10, 20 and 30 cm. Parameters determined include pH, Electrical Conductivity (EC), Magnesium (Mg), Calcium (Ca), Sodium (Na), Phosphorus (P), Nitrogen (N), Potassium (K), Organic Carbon (OC), Organic Matter (OM) and heavy metals such as Copper (Cu) and Lead (Pb) and subjected to relevant statistical analysis. Most of the parameters analyzed indicated pollution and were below the Food and Agricultural Organization (FAO) limits. P and Mg concentrations ranged from 1.19 to 1.25mg/kg and 3.17 to 13.61mg/kg respectively which indicated pollution. Out of heavy metals analyzed, Cu was 1.75mg/kg and Pb was not detected. Statistical analysis indicated signicant differences at 95% level. The result showed that the soil samples were mildly polluted and therefore not suitable for crop production.

The objective of the study was to evaluate the phytoremediation potential of three aquatic macrophytes (Commelina cyanea, Phragmites australis and Water Hyacinth (Eichhornia crassipes)) for treatment of municipal wastewater collected from Federal University of Technology, Akure (Nigeria). Laboratory scale of three constructed wetlands of dimensions 0.43 m x 0.93 m x 0.36 m in width, length and depth respectively, were developed to mimic natural conditions and was operated for a single experimental run with each macrophte at different retention time of 6, 9 and 12 days. These aquatic macrophytes were planted in separate ponds. Domestic wastewater from undergraduate students' hostel was introduced to the ponds. The raw wastewater sample and treated wastewater samples were analysed using standard laboratory methods for physical (Turbidity and Dissolved solids), chemical (pH, Nitrate, Nitrite, Phosphate, Sulphate Chemical Oxygen Demand and Biochemical Oxygen Demand) and bacteriological (Coliform bacteria) parameters. Results showed substantial diminutions in all parameters treated with the phytoremediators during the course of the study. Asides the three plants effectively removing Nitrate, Nitrite, phosphate and Sulphate pollutants, Phragmites australis gave the highest removal efciency for Phosphate (85.8%), Water hyacinth gave the highest removal efciency for pH (11.5%), Biochemical Oxygen Demand and Coliform bacteria and Commelina cyanea gave the highest removal efciency for turbidity (96.9%) and dissolved solids (82.9%) parameters of the domestic wastewater samples. The overall results of the phytoremediation studies indicate that the purication effectiveness of the three aquatic macrophytes were spontaneous, feasible and remarkable.

Rapid urbanization has greatly increased the volume of runoff generated in many developed areas and subsequently resulting in flooding. This study evaluated the flood prone area of Igbokoda town in Ondo State and developed a flood risk map to facilitate proper planning and future flood mitigation. Scientific technique of GIS was used to identify flood risk areas within the study area. The Landsat 5 (TM), Landsat 7 (ETM+) and Landsat 8 (LC) images for 1986, 1999 and 2013 coupled with STRM 90 m DEM data of the area were used to identify three categorized risk zones. A total of 339 basins were delineated and stream network on the landscape of this area were carved. Hydrological and vegetation cover analyses were conducted using the satellite imageries obtained from United States Geological Surveys Archive online over the study area for three different epochs 1986, 1999 and 2013. There was a sharp decrease in area of vegetation cover from 1986 (19,630 ha) to 1999 (16,527.36 ha) and in 2013 (12,246.80 ha). The hydrological analysis results revealed that a major part of the residential area within the largest basin delineated was associated with low elevation and high slope angle. The combined stream network and slope of the area were used in developing flood risk zones. Three zones were specified: high, medium, and low flood risk zones. The total area covered by the high risk zone was 28.5615 km 2 while the area of the medium and small risk zones were 15.94759 km 2 and 31.3619 km 2 respectively. It is recommended that an increased awareness on flood risk zone should be created among the populace of Igbokoda to guide them in further development.

An attempt was made to ascertain the environmental effects of animal wastes pollution on agricultural soil and water quality at the oldest teaching and research farm, Federal University of Technology, Akure, Nigeria. Physical, chemical , and bacteriological analyses of water (shallow well) and soil samples were carried out to determine the present quality status. Fifteen soil samples collected at the centre of the animal wastes dump and at a distance of 5 and 10 m, and three different samplings done on the water source were analyzed. The parameters determined using APHA standard procedures included: turbidity, temperature, pH, alkalinity, sulphide, phosphate, dissolved oxygen, total dissolved solids, total hardness, biochemical oxygen demand, total iron, nitrate, chloride, calcium, and heavy metals like copper, zinc, and lead. Most of the parameters indicated pollution including heavy metals presence with the exception of Pb, Zn, Mn, Cu, and Cr that were not detected in water samples. Concentrations of nitrate, biochemical oxygen demand, SO 4 2– , PO 4 3– , and Cl – were 0.20, 3.20, 10.50, 3.5, and 20.4 mg/l respectively, while those of detected heavy metals such as Mg and Ni were 1.98 and 10.03 mg/l, respectively. Soil water holding capacity, porosity, pH, organic matter, organic carbon, and organic nitrogen ranged from 33.34 ± 3.73 to 59.06 ± 5.69, 34.6 ± 3.28 to 52.43 ± 5.5, 6.56 ± 0.03 to 7.54 ± 0.03, 2.32 ± 0.03 to 5.35 ± 0.03, 1.33 ± 0.01 to 3.11 ± 0.01, and 0.58 ± 0.07 to 1.13 ± 0.03%, respectively. The results showed that the well is strongly polluted with bacteria and pathogens and requires considerable treatment before use while the soil is suitable for crop production.

Three tillage practices, Zero Tillage (ZT), Minimum Tillage (MT) and Conventional Tillage (CT) on infiltration capacity and other physicochemical soil properties were investigated using, double ring infiltrometer at two locations which were Agricultural and Environmental Engineering (AGE) research farm and Federal University of Technology, Akure (FUTA)ʼs Teaching and Research (T and R) farm. Soil physicochemical properties determined include; bulk density, porosity, moisture content, organic matter, organic carbon, pH, sodium, potassium, calcium and magnesium. Two models, Kostiakov and Philips were also used to model infiltration rates and results were compared with measured values and were subjected to statistical analysis. Linear relationship exists between infiltration rate and duration of water application and all infiltration rates decreased as time increased. High correlation (R²) values were obtained for the two farms and in the three treatments which were 0.979 and 0.984 for ZT, 0.962 and 0.996 for MT and 0.999 and 0.997 for CT for both AGE and T and R farms, respectively. Although, T and R farm has higher infiltration rates when compared with the AGE farm, Kostiakov and Philips models showed that Minimum Tillage (MT) on AGE farm was the best of all the tillage treatments considered.

This paper aims at establishing changes in land use and land cover in Igbokoda municipality using Geographic Information System and remote sensing techniques. Three satellite images for three different epochs 1986, 1999 and 2013 were used to produce a land use/land cover map classification for Igbokoda. In determining the extent of land use/land cover changes in the township from 1986 through 1999 to 2013, Landsat images of the town were downloaded from the United State Geological Survey online archive. The images were analyzed using change detection technique (NDVI differencing) along with SRTM 90m DEM of the study area to generate the extent of the changes that have occurred. Ground trotting was carried out to ascertain the accuracy of data and the major changes in the land use/land cover. Results show that vegetation has decreased from 75.04% in 1986 to 46.81% in 2013 which was due to increase in population and rapid urbanization. In 1996 the Built-up area covers 19.6321 km2 of the study area but has increased rapidly to 39.1505 km2 in the year 1999 with an average annual increment of 2.025Km2/year. By the year 2013, the built-up area has increased to 64.1520Km2. Also in the same vein, the bare surface area which was 13.28029km2 in 1986 was increased to 39.6053 and 50.240Km2 in 1999 and 2013 respectively. On the contrary, the vegetated area of Igbokoda reduced from 196.3046Km2 in 1999 to 122.4680Km2 in 2013. This study has demonstrated that remotely sensed data and GIS based approach is timely and cost effective than the conventional method of analysis, classification of land use pattern effective for planning and management. It further shows that If the rapid change in land use is not properly manage, the situation poses a serious threat to Igbokoda town by increasing surface runoff and susceptibility to flooding.

Stormwater management is becoming a problem in the city of developing countries due to rapid industrialization and poor infrastructure. Proper drainage system conveys stormwater from the road to a suitable disposal area. However, many of them are without functioning drains. The paper presents a sustainable approach to stormwater management in the developed area ofthe FUTA. The entire catchment area was divided into subcatchments that form the designated units for data collection. The result of the field work on the pervious and impervious area of the entire catchment showed that over half (57.31%) of the entire drainage area are grass land and the paved road covered 10.96%. the unpaved road and built up area covered 10.29% and 9.76% respectively. Others areas are thick forest (7.66%) and rock area (4.02%). The design of stormwater collection systems were based on the principles of hydraulics as explained by manning. The drain size was based on maximum discharge from each subcatchment and the time of concentration computed with Kirpich's formula. If this design is implemented, common flash flood and siltation along roads in FUTA will be completely eliminated

The increased use of fossil fuels for energy consumption has causes environmental problems both locally and globally. The study investigates the anaerobic digestion in the production of biogas a renewable energy from the digestion and co-digestion of three different types of biodegradable wastes (cow dung, fruit waste and food waste) as an alternative for fossil fuels for energy consumption. This was carried out using a 25 Litres capacity plastic keg prototype biogas plant, constructed to investigate the anaerobic digestion in generating biogas. The experiment was batch operated and daily gas yield from the plant was monitored for 30 days. The slurry temperature and pH were also monitored and presented. The digester was charged with these wastes in the ratio of 1:1, of waste to water respectively. The mesophilic temperatures range attained within the testing period were 25 - 28.4 and a slurry temperature range of 24.4 -28.4 . The result obtained from the biogas production showed that the co-digestion of cow dung and food waste produced the highest biogas of 164.8%, followed by the co-digestion of the three waste (cow dung, fruit waste and food waste) which has a percentage of 91.0%, co-digestion of cow dung and fruit waste (83.9%), cow dung of 79.8%, food waste of 77.4% and fruit waste of 76.4% within this retention period. During the digestion period, the volume of biogas production and the changes in pH indicate that the pH decreases as the retention period increases. These results showed that co-digestion wastes produce more biogas than when the wastes are ordinarily used for biogas production. The study recommends that biogas is not just a renewable energy source but also an appropriate way of managing waste, having potential to replace fossil fuel.

The disposal of wastewater is a problem of great concern throughout the world specifically in developing countries. This study investigates the impact of indiscriminate wastewater disposal on soil in Akindeko and Abiola halls of residence at the Federal University of Technology, Akure Nigeria. Soil samples were taken from the wastewater disposal site at the surface and varying depths of 10 cm and 20 cm while the control samples were taken 10 m away from the polluted soil surface. Physico-chemical and bacteriological properties determined include; colour, odour, soil weight, particle weight, bulk density, porosity, pH, Copper, Manganese, Zinc, Lead, Cadmium, Cobalt, Iron, Sodium, Potassium, Calcium, Magnesium, bacteria, fungi and coliforms. The results showed that all the physicochemical and bacteriological properties of the soils have relatively high concentration indicating pollution compared to the control samples. The pH ranged from 8.7 to 7.2 while Ca and K have a range of 1277 ppm to 773 ppm and 1273 ppm to 754 ppm respectively. The highest concentration of Zn and Mn are 19.30 ppm and 11.70 ppm respectively. It is recommended that a sustainable wastewater treatment plant should be provided to treat all wastewater generated from all hall of residence in the university and at the same time the soils in the area require various remediation technologies like bioremediation and phytoremediation by growing certain plants in the area to minimize the rate of contamination and extent of future pollution problems. This will go a long way in preventing environmental pollution in the study area.

Proper disposal of wastewater still remains a major concern in developing countries. As population grows and urbanization increases, more wastewater is generated and there is great awareness on the health and environmental implication of poorly disposed wastewater. This research work develops a sustainable approach to wastewater disposal in the Federal University of Technology, Akure. The existing wastewater disposal system in use in the study area is the septic tank - soakaway system for individual buildings. This approach presents serious problems due to the choice of inappropriate technology, improper siting of infrastructure, lack of adherence to correct design concepts and lack of proper maintenance.Wastewater samples were collected and their properties determined through laboratory tests to ascertain the concentrations of significant physical, chemical and bacteriological constituents for the selection of appropriate wastewater treatment processes. The total estimate of the wastewater generated from various locations was 2.075 million liters per day based on the population of approximately 26,131.Taking into consideration the available pipe sizes in the market a pipe size of 100 mm was found to be suitable for wastewater conveyance from the office and residential areas based on the contributory population. The proposed wastewater treatment plant (three anaerobic ponds of 57.42 m x19.14 m x5 m connected in series) is to be sited at the lowest topographical level which is of suitable distance from the office and residential areas. Implementing this wastewater management approach in the university will mitigate the negative effect of septic tank - soakaway system and present an environmentally sustainable wastewater management approach

Mining plays a vital role in national economic development and on the contrary mining undesirably impact our environment. Mining has increased rapidly due to the development of large-scale mines. This technique of mining disturbs large areas of land and water which need to be restored. The environmental problems arising due to mining activities are natural land degradation, air and water pollution with heavy metals, organic and inorganic waste, negative impact on terrestrial and aquatic ecosystems, human health and socioeconomic. Possibly, the weightiest after effect of a mining is its effects on water resources. The impact of mining on surface and groundwater is due to spill erosion, sedimentation, acid mine drainage, lowering of water table, subsidence, disturbance on hydrological cycle and rainfall. Acid mine drainage is regarded one of mining's most serious threats to water resources. A mine with acid drainage has the capacity for long term damaging impacts on rivers, streams and aquatic life. This study is an appraisal of mining impacts on water resources.

This study assesses the recovery of cobalt present in spent or waste lithium-ion batteries through hydrometallurgical process as a measure of prevention towards environmental and health problems resulting from improper disposal of these batteries. Spent lithium-ion batteries of three different mobile phone brands (Samsung, Nokia and Blackberry) were collected and separated/dismantled into four components (Inner roll, casing, plastic and paper). Six samples labeled 1 to 6 were analyzed in all. These components were initially weighed before leaching the inner roll in a shaker water bath. The leaching temperatures used were 70, 80 and 90 o C and the leaching time, 60 and 120 minutes. The quantities of hydrochloric acid used were 123, 246 and 344 ml with varying quantities of distilled water. The pregnant solutions obtained from leaching were filtered in order to remove impurities. A mass of 5 g of sodium hydroxide mixed with 60 ml of water was then added to 40 ml of the filtered pregnant solution to precipitate cobalt and the precipitated solution was filtered. Atomic Absorption Spectrophotometer (AAS) was finally used to analyze 2 ml of the leaching solution, filtered-pregnant solution and filtrate obtained after precipitation were all mixed separately with 98 ml of distilled water in order to determine the quantities of cobalt present in the solutions. The results of the analyses showed that cobalt leached was between 95.00 – 409.00 PPM with equivalent percentage recovery of 98.02 – 99.98% which signifies abundant availability of the metal in spent lithium-ion batteries. This recovery process of heavy metals can therefore serve as an effective means of preventing environmental and health problems associated with waste batteries.

The estimation of a dependable crop water requirement is a necessity for sustainable and effective irrigation application. The estimation of crop water requirements of soybean was carried out based on twenty-one years meteorological data at Abeokuta using Penman– Monteith model. The results obtained showed that the monthly crop reference evapotranspiration (ET o) varied from 96.90 to 165.23 mm/month. The highest crop evapotranspiration (ET c) value of 121.38 mm/month was observed in the month of October while the lowest ETc value of 32.75 mm/month was observed in the month of November. The seasonal effective rainfall (ER) and irrigation water requirements (IR) are 411.57 mm and 108.35 mm respectively. ET c was higher than ER for the months of August, October and November which concise with the vegetative, reproductive and maturity growth periods. This could be caused by the less precipitation recorded in the months of August, October and November. Supplementary irrigation is required to meet the crop water requirement of soybean sowed in Abeokuta during the growth stages where the effective rainfall is lower than the crop evapotranspiration. INTRODUCTION The availability of water in the soil is an essential life support for plant development and food production and sustainability. The amount of water needed during a growing season depends on the crop, yield goal, soil, temperature, solar radiation and other cultural factors. The amount of irrigation required for crop production depends on the particular season's useful rainfall, the soils' water holding capacity and the crop water need (Adekunle et al., 2017). Soybean is a leguminous food crop with vast nutritious content. It serves as a cheap and economical source of oil and protein for millions of people in the world and as feed supplements for poultry and livestock industries. It can be cultivated on almost all kinds of soils expect deep sands which are characterized with poor water retention. The crop is widely cultivated in the tropics and subtropical region of West Africa, characterized by erratic rainfall pattern and periodic dry spells. Soybean is basically a short-day plant, but the response to day length varies with variety and temperature. It is most susceptible to drought damage during flowering and grain filling (Eteng and Nwagbara, 2014). However, the deficiency of water to meet the evapotranspiration demands of soybean during the reproductive growth stages might lead to substantial reduction in its yield. Understanding the crop water needs is essential for irrigation scheduling and water saving measures during the dry period of the cropping season (Eteng and Nwagbara, 2014). Consequently, estimating irrigation water requirements accurately is vital for the survival of crops especially during the dry season. Water requirements for maximum production of soybean ranged from 450 – 700 mm which would be well distributed over the growing season. The crop needs frequent watering especially early yield formation (pod development). Water deficits just prior and during flowering and early yield formation (pod development) may cause heavy flower and pod dropping (FAO, 1986). Crop water needs of soybean fluctuate throughout the season depending on climatic conditions and crop growth stages. Evapotranspiration is one of the key processes in the hydrological cycle and it is the loss of water to the atmosphere by the combined processes of evaporation from the soil and plant surface and transpiration from plants (Allen et al., 1998).

The behavioural effect of different types of fertilizer application on Amanthus curentus was examined. One organic and inorganic fertilizer each was considered for this study. Standard rates of cow dung (16 t ha-1); NPK (0.25 t ha-1) and control (no fertilizer) were administered to a 5 X 5m2 plot using randomized complete block design (RCBD) with three treatments and three replicates. Parameters measured were plant height, leaves number, biomass and edible yield and were subjected to statistical analysis using SPSS 16.1 version at 95% level of significance. Final biomass yield of the vegetable for cow dung, N.P.K and control were 30,667±5.22 kg ha-1, 60,408± 2.45 kg ha-1 and 46,825± 10.22kg ha-1 respectively while edible yield were 11,125 ±5.54 kg ha-1, 20,925±6.43 kg ha-1 and 11,092±3.33 kg ha-1. Agronomic responses to the three treatments 7 weeks after planting (WAP), 18.83±2.30 cm for cow dung, 23±2.75 cm for the NPK and 17.75±2.40 cm for the control respectively. Plant height responses to the treatment were 70.08±5.45 cm for cow dung, 108.42±5.89 cm for NPK and 89±1.32 cm for control respectively in the same WAP. NPK was outstanding in all treatments during the experiment going by the responses. Usage of raw cow dung was not encouraged due to the possibility of Escherichia coli and NPK has proved to be the most suitable fertilizer.

Irrigation is considered an essential factor for agriculture and food security and therefore this study focused on the assessment of major systems and challenges of irrigation practices in Ondo and Ogun States, Nigeria. Structured questionnaire were administered to farmers in generating information used. Demography of the farmers showed that majority of them was males (84%) while only (11%) female were from Ogun state. Most respondents (89%) were aged 45 years and above while the least-represented age group was less than 35 years. Educationally, over 63 % had formal education out of which only 5 % of respondents had primary education. The response showed that majority of the respondents in the study area practiced surface irrigation which accounted for 57% of the types of irrigation considered. Sprinkler (26%) and drip (13%) irrigation respectively were practiced by the farmers. However, lack of technical knowhow, inadequate knowledge of crop water requirements and irrigation scheduling strategies were the greatest challenges to sustainable small-scale irrigation in the study areas.

Waste disposal and management is a disturbing issue in most developing countries. Domestic waste generation in most Nigerian cities has increased prodigiously and management of waste in the country is not satisfactory; despite environmental sanitation programme adopted by government. This research has highlighted the solid wastes generation from an institution in the city, domestic and market areas. Solid waste samples were collected from different locations and their relative compositions were determined by sorting them into different categories. The solid waste was sorted into recyclable, compost and non-recyclable components which should be disposed into the landfill. The results of the composition of solid wastes generated in the institution (FUTA): plastics 11%, textiles 9%, papers 26%, tin 12%, food waste 21%, and nylon 18%. The percentage composition of food wastes is 21% for compost, 68% of recyclable components while, 2% were non-recyclable components. The results obtained from solid wastes generated in the market area: plastics 13%, textiles 8%, papers 16%, tin 12%, biodegradable is 24% for compost, 74% of recyclable components while, 2% were non-recyclable components. The results obtained from solid wastes in domestic area: plastics 14%, textiles 11%, papers 14%, tin 12%, food waste 16%, glasses 8% and nylon 11%. The percentage composition of food wastes is 15.81% for compost, 68% of recyclable components while, 2% were non-recyclable components. The results of this work will help to determine the best way of disposing and treating waste. It will also help waste managers and planners in making good decisions in terms of the waste usage.

Currently, energy problems are faced all over the world, majorly African countries. One of the solutions in the challenging energy situation is utilization of renewable energy. Even countries that are rich with fossil fuels have identified the necessity of developing alternative sources of energy. Nigeria is endowed with abundant natural renewable energy resources like the solar, wind, hydro, biomass (waste) etc. Renewable energy will be a pragmatic alternative to supplementing electricity supply in Nigeria. It can be cost-effective in areas far-flung from the national grid, and will impact Nigeria's electricity bottom line. However, the economy has mainly relied on the consumption of oil and gas for commercial energy. There is therefore a growing global concern about the future of non-renewable biomass in form of fossil fuel and its attendant consequences on the environment as evident in global warming. Moreover, there is an ever growing demand for energy. Biogas, a form of renewable energy can provide a clean, easily controlled source of renewable energy from organic waste materials for a small labour input, replacing firewood or fossil fuels which are becoming more expensive as supply falls behind demand. Thus, this paper centres on the past and present status of energy in Nigeria and Africa at large and potential of renewable energy from organic wastes citing several case studies.

The current inadequate drinking water services and sanitation problems have incited the need for a better management strategy by the country's water and sanitation organizations. In this study, a logical review of the water supply and sanitation origin and management structures was done to suggest a plausible management option in Nigeria. The paper also revealed that the overall management practices of these organizations at the three tiers of governments (federal, states and local) is very poor and uncoordinated which have resulted in low level of water and sanitation coverage. Thus, in order to ameliorate these problems, the study recommends sector wide reforms with the aim of radical improvement in the management processes of these organizations. Other
proposed improvement strategies include: private sector participation, effective and reasonable tariff regime for effective cost recovery, increment in political support and leadership commitment, introduction of benchmarking amongst the utilities to encourage healthy competition, strengthening of the legislative and institutional framework- that will enhance the autonomy of these organizations, improvement in the issues of accountability, transparency and stakeholders involvement in the activities of these organizations. It is hoped that the adoption and implementation of these strategies will lead to attainment of improved and sustainable water supply and sanitation coverage that will meet current and future demands.

Creativity has become a buzzword in our society. Everything from a child's scribble to Einstein's theory of relativity is considered creative. Not so in the Scriptures! In the Bible "create" is reserved for extraordinarily exalted activity. The Hebrew and Greek words for it, respectively, “bara” and “kitzo”, are very similar in meaning and are employed sparingly to denote only the pinnacles of God's achievements - creating the heavens and the earth, man, righteousness/justice, the nation Israel, the Church, reconciling Israel and the Church, creating the New Jerusalem, and to regeneration and worship

Hand-dug wells are widely used in developing countries and in many areas for hundreds of years. There are also a large number of donor-funded rural water supply projects based on the construction of hand-dug wells. Hand-dug wells are constructed with simple tools in weathered rock, overburden or sedimentary formations. The well is lined to the aquifer with concrete rings. Penetration into the water-bearing zone can be done with caisson rings. This allows further deepening of the well in case that the water table falls. Construction can be done with a high degree of community participation. Digging and the construction work give the villagers a chance to contribute. They can work on their facility under supervision from the construction company. Alternative designs employ different lining methods such as in-situ lining by casting concrete into moulds, cement block lining, ferrocement lining.

Surface runoff consists of that portion of the precipitation reaching the surface that neither infiltrates into the ground nor is retained on the surface. The quantity of surface runoff is
controlled by a complex variety of factors. Included among these are precipitation intensity and duration, permeability of the ground surface, vegetation type and density, area of drainage basin, distribution of precipitation, stream-channel geometry, depth to water table, and topographic slope. Also, in this term paper, runoff processes, runoff components, polluted runoff, runoff effects, mitigation and treatment of runoff and methods of estimating runoff were discussed.

The research focused on the management of stormwater and sewage generated in a
developed urban area - Federal University of Technology, Akure, Ondo State, Nigeria. This involved the design of sanitary sewers, stormwater collection networks and a central sewage treatment plant. The total estimate of the wastewater generated from various locations was 5.067 million litres per day based on the population of approximately 26,131. The existing sewage disposal system in use in the institution was the septic tank-soakaway arrangement for individual buildings. The design of the sanitary sewers and stormwater collection networks are based on the principles of hydraulics. The results obtained were used to analyze and design the drains and pipe sizes for the open channels and the closed conduits respectively. The size of the drains for stormwater collection networks was designed with the assumption of 0.75 and 1 meter width. Also, calculations were made for square drain (depth equals width)
to be able to select practicable sizes. For optimum size solution, pipe size of 100 mm was found to be suitable for wastewater conveyance from the office areas. The sizes of pipes calculated for flows from residential quarters are too small, hence available commercial pipe sizes were selected. Wastewater samples were collected at various locations and were determined through laboratory tests to ascertain the concentrations of significant physical, chemical and biological content of the wastewater for proper selection of appropriate treatment processes. A BOD concentration of 350 mg/l and 353 mg/l obtained for residential and office areas respectively translated to high pollution load requires treatment before ultimate discharge into the receiving stream. The proposed sewage treatment plant was sited
at the lowest topographical level, far enough from the office and residential quarters. This would allow flow by gravity from the various points. The sewage treatment plant components selected include screen chamber, grit chamber, skimming tank and rectangular/circular primary settling/sedimentation tank (PST), which are designed to optimal dimensions.

The effectiveness of water hyacinth (Eichhornia crassipes) for the purification of
sewage was investigated. The study was carried out in the Department of Agricultural
and Biosystems Engineering. Three treatments of water hyacinth replicated two times
were used in the study. These treatments include no water hyacinth (control), 1kg and
2kg water hyacinth plant density cultures. The system was designed based on Completely
Randomized Design (CRD). Sewage samples were collected during the growth of water
hyacinth. Purification of water hyacinth (Eichhornia crassipes) on sewage was rapid
during the first three weeks in the sewage cultured with water hyacinth (especially 2kg
water hyacinth plant density) and there was low absorption in nutrients in the last two
weeks when attaining maturity. Parameters such as Cl-, Fe, Cu, Mn, Pb, K, F-, Nitrate and
Sulphate were drastically reduced from 9mg/l to 3.33mg/l, 1.25mg/l to 0.36mg/l, 0.3mg/l
to 0 mg/l, 0.5mg/l to 0.08mg/l, 0.2mg/l to 0.01mg/l, 1.7mg/l to 0.17mg/l, 0.7 mg/l to
0.08mg/l, 8.6mg/l to 0.03mg/l, 17.5mg/l to 6.20mg/l respectively throughout the course
of the study. The purification by water hyacinth had no effect on the bacteriological
parameters (Agar count, E-coli, Coliform). Also, the 2kg water hyacinth plant density
cultured in the sewage purifies more compared to the 1kg water hyacinth plant density
which is moderate and minimal in the control treatment. One way analysis of variance
was used to compare the means of the parameters tested. It shows that parameters like
CO2, Mn, lead and sodium have significant difference between the control treatment with
both the 1kg and 2kg water hyacinth plant density culture while parameters like pH,
magnesium hardness, calcium hardness and calcium total have no significant difference
between the no water hyacinth culture( control) with the 1kg and 2kg water hyacinth
plant density culture. Finally, sewage parameters like BOD, COD, dissolved oxygen, Cu,
F-, nitrate, phosphate, potassium, dissolved solids, suspended solids, sulphate, iron, Cl-
and magnesium total were not affected.

Dyes, especially from textile industries, are significant pollutants in water and wastewater, which have become pervasive in the environs to which they are discharged. The effluents containing different types of dyes have become ubiquitous in the environment. While several treatment techniques have been developed to address the removal of recalcitrant dyes from water and wastewater, the adsorption technique is highly preferred due to its many advantages. However, selecting the appropriate alternative adsorbents with high adsorption capacity to costly activated carbon has continued to receive great attention. This book chapter reviewed the applicability of adsorptive techniques of agro-waste based adsorbents for the removal of dye pollutants from water and wastewater. The mechanisms of persistent dye pollutant removals based on the adsorption processes were adequately described. Further, the strengths, weaknesses, opportunities and threats (SWOT) of using
agro-waste materials as alternative adsorbents are also accounted.
