  Levels of Copper (Cu), Cobalt (Co), Zinc (Zn), Iron (Fe), Lead (Pb), Manganese (Mn), Chromium (Cr), as well as pH, redox potential (Eh), Dissolved Oxygen (DO), Total Dissolved Solid (TDS), temperature, nitrate, sulphate and phosphate were determined in River Challawa, Kaon State, Nigeria. These parameters were simultaneously monitored. Physio-chemical examination revealed that the levels of pH (6.81±0.10 and 10.23±0.32 mg L 1), Eh (-46.31.34 to -87.21.54m/v), TDS (40.33.24 to 70.18.40 mg L 1), temperature (8.20.14 to 12.80.24 C), sulphate (22.60.21 to 43.50.31 mg L 1) and nitrate (1.110.02 to 4.040.03 mg L 1) were below the maximum permissible limits set by WHO and FEPA for drinking water and aquatic ecosystem. Concentration of heavy metals; Cu, Co, Zn, Fe, Pb, Mn and Cr were significantly above the maximum allowable levels set by United State Environmental Protection Agency (USEPA) and WHO levels for drinking water and for protection of aquatic ecosystem. The levels of DO and phosphate in the water samples exceeded the Nigeria Federal Environmental Protection Agency (NFEPA) tolerance limits for drinking water and water meant for domestic uses. This may have deleterious effect on aquatic ecosystem and the health of the rural dweller that use the river water directly for domestic purposes without treatment.

  Concentration of dissolved copper (Cu), cobalt (Co), zinc (Zn), iron (Fe), lead (Pb), manganese (Mn), chromium (Cr), as well as pH, redox potential (Eh), dissolved oxygen (DO), Total Dissolved Solid (TDS), temperature, nitrate, sulphate and phosphate were determined in River Challawa and tap water from Challawa, Sharada and Bompai industrial areas, Kano State, Nigeria. Samples were collected for a period fifteen weeks. River Challawa is the main water supply source for Kano town and numerous industries within this area. Apart from being a source of water supply, it serves as a sink for industrial and municipal wastes. These parameters were simultaneously monitored. Physico-chemical examination revealed that the levels of pH (6.81±0.10 to 10.23±0.32), Eh (-46.3±1.34 to -87.2±1.54 mV), TDS (40.3±3.24 to 70.1±8.40 mg L-1), temperature (8.2±0.14 to 12.8±0.24°C), sulphate (22.6±0.21 to 43.5±0.31 mg L-1) and nitrate (1.11±0.02 to 4.04±0.03 mg L-1) in River Challawa and tap water from Challawa, Sharada and Bompai industrial areas were below the maximum permissible limits set by WHO and Federal Environmental Protection Agency (FEPA) Nigeria for drinking water and aquatic ecosystem. Concentration of heavy metals; Cu, Co, Zn, Fe, Pb, Mn and Cr in River Challawa were significantly above the maximum allowable levels set by United State Environmental Protection Agency (USEPA) and WHO levels for drinking water and for protection of aquatic ecosystem, while for tap water the concentration of heavy metals were within safe limits. The levels of DO and phosphate in River Challawa exceeded the FEPA tolerance limits for drinking water and water meant for domestic uses. This may have deleterious effect on aquatic ecosystem and the health of the rural dwellers that use the river water directly for domestic purposes without treatment.
