The study was carried out to ascertain open water quality for human consumption in a high density area where the source of water is limited to open wells and where there are no consideration giving between open well and a pit latrine, soak ways and drainages. Stratified random sampling techniques was use to select nine open wells where samples were taken three times to ascertain and validate the result of the water analysis. Coli form test was used to determine the presence of microbial contaminates, pocket conductivity meter was used to determine the concentration of some chemical element and compound and spectrophotometer was used to analyze some physical parameters. From the result of the analysis it was discovered that nitrate exceed the limit in about 75% of the samples analyzed while e-coli bacteria was detected in 8 out of the 9 samples analyzed. But Iron was found to fall below the minimum requirement. The study while considering that the sources of both nitrate and e coli i...

River Basin Development Authorities (RBDAs) in Nigeria were established since 1976 and they operate mechanized and capital intensive programmes. All the 12 RBDAs operate as separate Authorities, each with separate administrative and operational autonomy, but sharing the Basin Resources of the 8 Hydrological Areas. However, their performance was generally described as disappointing. This study first reviewed the existing organization of the 12 RBDAs in Nigeria. Thereafter, one of the 8 Hydrological Areas – the Komadugu-Yobe Basin (KYB) – which is the major inland drainage system in Nigeria was purposely selected for detailed study.  Information on its major streams, tributaries and the main river; the hydrological area as well as the RBDAs sharing resources of the basin area, was gathered using ArcGIS version 10.0 and Erdas Imagine 9.2 software, as well as topographical and hydrological maps. This was processed and analyzed based on the principles of Stream Ordering and Logical Frame...
