Assessment of Water Quality for Goro Dong (Lake) and Its Suitability for Consumption and Domestic Use by the Immediate Lake Communities in Numan, Adamawa State Nigeria

The suitability of Goro Dong (Lake) water for human consumption has been examined using the Weighted Arithmetic Water Quality Index Method. Water samples were collected from the lake in the month of March 2017 and subjected to standard physicochemical tests. Parameters used for the water quality analysis include pH, Electrical Conductivity, Total Hardness, Total Alkalinity, Total Dissolved Solids, Total Suspended Solids, Sodium, Magnesium, Calcium, Chlorides, Sulfates, Nitrates, Dissolved Oxygen and Biochemical Oxygen Demand. The drinking water standards employed included those of World Health Organization (WHO), Nigeria Industrial Standard (NIS) and Indian Council of Medical Research (ICMR). Results revealed that the observed values of all the parameters were within the permissible limits provided by the employed standard agencies. However, the overall Water Quality Index (62.34) indicated that the water quality is poor and thus require minor treatments before drinking.
