Rapid Assessment of the Water Chemistry of Public Water Supply in Abeokuta, SouthWest Nigeria

The study examined the water supply situation in Abeokuta, with emphasis on the quality of water distributed by the Ogun State Water Corporation from the treatment plant of the Abeokuta Water Scheme. Water samples were collected from standpipes (taps) across the city randomly selected using the stratified random sampling method and was analysed for physical and chemical parameters: pH, total dissolved solids (TDS), electrical conductivity (EC), total alkalinity, total hardness, calcium, magnesium, potassium, sodium, nitrate, bicarbonate, sulphate and chloride. The result of the physical and chemical parameters was subjected to statistical analyses using the multivariate t-test. The result of the treated water was further compared with the result of the analyses of raw water obtained from the source of water used in the treatment plant.
