Abstract
This study focuses on the quality of water at Bosso Lake during the rainy season months of August to October. Water samples collected each month were examined for their physiochemical and bacteriological attributes. All the samples were obtained during the peak of the rainy season while traits such as nitrate concentration, pH values, total dissolved solids (TDS), total hardness, iron concentration, suspended solids, calcium hardness, total coliform count and Escherichia coli were analyzed. The results showed variations in concentration of the parameters with respect to rainfall intensity and frequency. Although, results indicate that most of the physiochemical parameters were within the acceptable range of the Nigerian Standard for Drinking Water Quality nevertheless the high concentration of pathogens in the raw water renders it non-potable.
Key words: Raw water, Bosso Lake, water quality, physico-chemical, coliform.
