Abstract
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
ten water samples from three different water supply sources were collected and analyzed for
various water quality variables of interest. The field survey was carried out between April and May
2009. From survey results, surface and groundwater 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 that water from all the
sources investigated is generally slightly acidic, while levels of cadmium were higher than the
Nigerian Standard for Drinking Water quality limit of O.003mg/l specified for potable water supply.
The results of chemical and microbiological analyses also reveal impairments in quality of River
Atuwara, a major source of domestic water supply and intake for the state public water work with
high levels of Pb, Ni and Total Coliform. 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 well treated.
