Quality Evaluation Of Water From National Root Crop Research Dam For Irrigation:- Onyedim, John I.

ABSTRACT

 A Water quality has become a major concern due to ever increasing human developmental activities that over exploit and pollute the water resources. In the present study, water samples were collected from four different locations and a physico chemical study of the water from National Root Crop Research dam in Umudike, Ikwuano Local Government of Abia State has been carried out to examine the suitability of water for irrigation purpose. In this study, all the parameters such as TDS, pH, alkalinity, total hardness, chloride, Sulphate, nitrate, fluoride, Iron, Calcium and magnesium were found to be within WHO and FAO permissible limits. The pH values obtained from the dam water lies slightly below WHO and FAO permissible limits. Electrical conductivity value and Chloride value of the dam water samples lies in the range of medium salinity zone. Therefore water of these dams can be used for irrigation purpose.
