Twenty four (24) groundwater samples were collected from some selected areas in Warri Metropolis, Delta State in the Niger Delta area of Nigeria. The areas covered include: Udu, Ajaminogha, Edjeba, Bendel Estate, Enerhen, Igbudu, Jakpa and Eboh. The quality of these private borehole water samples was assessed using methods recommended for water quality by America Public Health Association. The water samples were analysed for physico-chemical and microbial parameters so as to ascertain their potability. The results revealed that pH was relatively low in all the waters with values varying from 4.15 to 4.86 pH. All the groundwater samples could be termed ‘freshwater’ as revealed in the total dissolved solids (TDS) and salinity levels, which ranged from (61.33 mg/L to 277.0 mg/L) and (12.55 mg/L to 82.59 mg/L) respectively. The mean turbidity values varied from 0.11 to 1.17 NTU. The water samples were fairly soft as revealed in the results for total hardness (12 – 16 mg CaCO3/L). Total iron, copper and zinc had concentrations levels within the local (Nigerian) and International [World Health Organization (WHO)] standards. Concentrations levels of these metals in the sampled locations were in trace quantity. However, lead, cadmium and chromium were not detected in any of the samples analyzed. It has been known that intake of water with low pH values could cause some severe health implications including gastrointestinal disorders and ulcers. This assessment was necessitated due to the fact that individuals resort to digging their privately owned boreholes, since the Government public utility water services have failed and do not supply potable or domestic waters to residences in these areas. In this vein, since residents in these areas use the untreated water from such borehole extensively for drinking and major domestic purposes, there may be likely health and environmental implications.
