This study investigated the sources and quality of domestic water supply to 124 households in 16 communities of Ado-Odo/Ota Local Government Area of Ogun State, Nigeria. In order to achieve the set objective, field surveys as well as administration of questionnaires were carried out while a total number of ten water samples from three different water supply sources were collected and analyzed for various wastewater and water quality variables of interest. The field survey was carried out between April and May 2009. From survey results, surface and ground water are the two major water supply sources in the investigated area. On coverage level, only 1.6% of the sampled population is serviced by pipe borne water from the state water works while 79.1% and 17.7% obtain their domestic water supply from groundwater and surface water sources respectively. The remaining 1.6% of the sampled population is serviced by private water vendors. Laboratory results show water from all sources is generally slightly acidic, while levels of cadmium were higher than the Nigerian Standard for Drinking Water quality limit of 0.003mg/l specified for potable water supply in all water supply sources. The results of chemical analyses also revealed impairment in quality of River Atuwara, a major source for domestic water supply and intake for the state public water work with high levels of lead and nickel. The water quality status of the various sources of domestic and public water supply in the surveyed area is unsafe and thus poses health concerns to users if not adequately treated.
