ABSTRACT
Water quality analysis was conducted using physico chemical and biological parameters on water samples collected from boreholes (B1, B2, B3 and B4) and hand dug wells (W1, W2, W3 and W4) eight wards Rogo Town, Kano Sate, Nigeria in order to determine its suitability for drinking in enriched in WHO standards for drinking water. Fourteen (14) water quality parameters, namely pH, temperature, total alkalanity, total acidicity, dissolved oxygen (DO), 5-day biochemical oxygen demand (BOD5), total coliform, odour, taste, color, clarity, total hardness calcium (Ca),and magnesium (Mg). Results obtained showed that the mean pH readings ranges from 6.2 – 6.6 and temperature of the sample ranges from 24 °C – 27 °C. Total alkalinity ranges from 63-80mg/l, total acidity showed a great variation between the hand dug wells and borehole samples. DO concentrations of hand dug wells were less than that of boreholes and did not meet the WHO unit (5 -14 mg/l). The BOD5 of both boreholes and hand dug wells water sample were within the WHO standard (2 – 4 mg/l) for drinking, except borehole water sample from B4 with BOD value of 1.9. The water samples from both sources were odorless, colorless, tasteless and clear for consumption.
