Abstract
Underground wells are widely used as source of water for household needs and other purposes in rural communities. Water quality and quantity are necessary requirements for use of water for various purposes, and ground water quality problems have been created anthropogenically and have become a menace to the users. This study therefore focused on the physiochemical and microbiological quality of hand dug well waters in a rural settlement in Rivers State. Sampling points (wells) were randomly chosen from wells operational in the sampling communities of Akabuka, Obagi and Obuburu. Physicochemical parameters were analysed using standard analytical procedures and aerobic plate count (APC) as well as most probable number (MPN) techniques were used for microbiological analysis of water samples. Results revealed that pH of the sampled wells were acidic compared to the permissible range. Other physicochemical parameters were lower than the permissible ranges for drinking water quality. Sampled well waters had high load of total aerobic heterotrophic bacteria (THB), total coliform bacteria (TCB), and faecal coliform bacteria (FCB)/thermotolerant coliform bacteria (TtCB) far above the permissible limits for potable water. Occurrence of faecal coliform bacteria/thermotolerant coliform bacteria in all the sampled wells indicated faecal contamination, and high load of aerobic heterotrophic bacteria revealed organic contamination of the water sources.
