Abstract:
Groundwater is generally considered a safe source of drinking water because it is abstracted with low microbial load with little need for treatment before drinking. Bacteriological assessment of boreholes and well waters in some selected locations within Akungba-Akoko, Ondo state, Nigeria were studied to determine the level of contamination of drinking water which might be responsible for the occurrence of water borne diseases. The study used standard laboratory techniques for the water quality analysis and the results were evaluated based on the benchmark standards of the World Health Organization and Nigerian Standard of Drinking Water Quality. According to the borehole water analysis, the total bacterial count (TBC) was extremely high in Akunmi 1, Ilale 1 and Okele boreholes and quite moderate in the other locations but was lowest in Etioro. The variation showed that the bacteria counts in the wet season where really high than those in the dry season. The total coliform count (TCC) and feacal coliform counts (FCC) were constant in both seasons. The TCC and FCC of both seasons were not more than the WHO and NSDWQ standards which is not above 10 cfu/ml. Therefore, groundwater obtained from both boreholes and wells in Akungba-Akoko metropolis were suitable for drinking and human consumption.
