The main objective of the study was to identify the processes governing the water chemistry of Narmada River and evaluate its suitability for irrigation. The physical parameters estimated were; pH (7.9 + 0.4 for pre-and 8 + 0.4 for post-monsoon seasons), EC (322.8+93.3 μS/cm for pre-and 312.1+80.2 μS/cm for post-monsoon) and TDS (203.4+41.5 mg/L for pre-and 213.4+48 mg/L

Samples were collected during summer, monsoon, and winter seasons. The analytical and GIS results show that concentration of electrical conductivity, chloride, and nitrate are higher in summer than monsoon and winter. However, the concentration of major cations such as sodium, potassium, calcium, and magnesium are higher in winter than monsoon and summer. In addition, major anions like sulphate and phosphate concentration is higher during monsoon than summer and winter. Multivariate statistical tool (discriminant analysis) results suggest that temperature, pH, electrical conductivity, sulphate, and potassium are the major parameters distinguishing the water quality in different seasons. The study confirms that seasonal variations are playing a major role in the hydrochemistry of KT wetland. Overall, this work outlines the approach towards proper conservation and utilization of wetlands and to assess the quality of surface water for determining its suitability for agricultural purposes. Overall, this work highlights the approach towards estimating the seasonal dynamics of chemical species in KT wetland and its suitability for irrigation purposes.

Water samples throughout its stretch right from origin point at Amarkantak to Badwani covering 10 sampling stations with 34 sub-sites of Narmada was sampled for water quality. The physiochemical parameters such as pH (8.38), EC (356 (252.8 mg/L), Alkalinity (157.8 mg/L as CaCO), Chloride (58.7 μS/cm), TDS 3 mg/L), Total Hardness (161.9 as CaCO mg/L), D.O (4.7 mg/L), B.O.D (2.4 mg/L for 5 days at 20 ºC), and nitrate (1.8 mg-NO /L) were within the 3 3 permissible limits as prescribed by the regulatory agencies. The interpreted comprehensive pollution index was 0.05-0.11; indicating that the river is clean.

Water samples were collected from 6 major sampling stations with 17 sampling points. Nine water quality parameters were analyzed to calculate the water quality index (WQI), followed by multivariate statistical evaluation. The results indicated that water quality in the upper Narmada varied from excellent to very poor – comprising excellent for approximately 12%, good for 17%, poor for 59%, and very poor for 12% of pre-monsoon samples, but excellent for 17%, good for 12%, and poor for 71% of post-monsoon. While the general water quality in the Narmada was poor, anthropogenic inputs such as domestic sewage and agricultural runoff influenced some parameters – e.g. BOD, nitrate, and total coliform. More studies are required for completing water quality evaluation.

Modern civilization, industrialization, urbanization and increasing populations have led to rapid degradation of groundwater quality. It is estimated that approximately one-third of the world's population use groundwater for drinking. Those around Varanasi depend totally on groundwater resources. Heavy and constant groundwater use, without restriction, is lowering both the water table and water quality. Any type of contamination present in groundwater, will leads to several health related problems. Owing to this pressure on resources, the water quality around Varanasi, in the middle Ganga plain, was studied. Twelve water quality parameters (iron, nitrate, fluoride, chloride, pH, TDS, alkalinity, turbidity, sulfate, calcium, magnesium, and hardness) were investigated relating to 2015/16 for eight blocks of Varanasi district. Groundwater quality was calculated by using correlation, principle component analysis (PCA) and water quality index (WQI). In general, good water quality was found in all but one block Kashi Vidya Peeth has poor water quality.
