Abstract

This study assessed the physicochemical and microbial quality of different types of water available for consumption and utilisation in Kwale, Delta State. Three water samples viz; well water, borehole water and sachet water were collected aseptically into a container and transported to the laboratory for physicochemical and microbiological investigations. Physicochemical analysis was carried out for dissolve oxygen (DO), biochemical oxygen demand (BOD), pH, total alkalinity, water hardness salinity and conductivity. Microbiological analysis was carried out for the presence of total coliform bacterial. The results of physicochemical parameters analyzed for the different water samples showed that Well water ranged between 0.5–0.9mg/L, 0.50–0.65mg/L, 6.00-6.99, 9.90-10.20ppm, 0.04-0.10mg/L, 0.10-0.70mg/L and 10.0-10.40µS, borehole water raged between 0.3-0.9mg/L, 0.40-0.55mg/L, 8.00-9.00, 11.0-15.0, 0.14-0.18ppm, 0.10-0.30mg/L and 9.10-10.20µS while sachet water ranged between 1.19–1.27mg/L, 0.03-0.40mg/L, 8.74-8.90, 11.0-13.5, 0.10-0.10ppm, 0.10-0.30mg/L and 10.30-10.70µS for D.O., BOD, pH, alkalinity, water hardness, salinity and conductivity respectively. Two species of gram-negative bacteria which include Escherichia coli and Enterobacter
aeruogenes were isolated and identified in the water samples. The prevalence of the bacteria in the different water samples showed that E. aeruogenes was most occurring in the water samples. E. aeruogenes was present in well, tap and sachet water samples but was most occurring in sachet water samples and tap water sample. Well water sample showed the presence of E. coli and E. aerogenes respectively
