Seasonal studies of water quality in partially protected shallow wells in Akure, Nigeria were carried out. The well waters were of high chemical quality, but higher values of parameters in the early rainy season than in the dry season indicate runoff water inflitration. Consequently, the waters show slight turbidity for one to two hours after rainfall due to settleable solids, a factor which renders the wells liable to chemical and bacterial contamination from surface sources. There is therefore a need for a design of drinking water wells in Akure to include making the wells deeper, at least 6 metres deep, and incorporating watertight lining of the upper part.
