Hydro-chemical Characteristics of Surface Water and Its Suitability for Drinking at Kwanar-Are Dam, Rimi Area of Katsina State, Nigeria
Hassan, M. and Ibrahim, M.

The present study investigated hydro-chemical characteristics of Kwanar-Are dam water and its suitability for drinking purposes at Rimi Area of Katsina State, Nigeria. Water samples were collected using clean dry polythene sample bottles of (1 liter capacity) during the rainy season of 2018. Concentration of dissolved oxygen (DO), biological oxygen demand (BOD), total alkalinity (TA), chloride (Cl¯), total hardness (TH), sulphate (SO4), nitrate (NO3), calcium ion (Ca2+) and magnesium ion (Mg2+) were analyzed and compared with standard limits recommended by Nigerian Standards for Drinking Water Quality and World Health Organization. The result obtained revealed that, all parameters were found within the desirable limit of drinking water standards. Water Quality Index (WQI) was employed to assess the suitability of the water for drinking and the result indicated that, the quality of the water was very poor and concluded that the water is unfit for human consumption sol also irrigation. It is recommended that, further treatment is required before use and surface water management plan is needed to improve the quality of the water
