Abstract

Some physiochemical parameters of potable water supply in relation to surface water, shallow well and borehole water in Warri area of Niger Delta region of Nigeria were assessed to determine their pollution profiles. Parameters such pH, turbidity, total suspended solids (TSS), chemical oxygen demand (COD), dissolved oxygen (DO), sulphate, phosphate, chloride and bicarbonate in the different water supply were determined. With few exceptions, the ranking of physicochemical parameters is in the order: surface water > shallow well water > borehole water. Some of the parameters were above WHO standard for drinking water, so there is need for strict monitoring to ensure quality water supply for human health.

Key words: Physicochemical parameters, potable water supply, pollution profile, Warri, Niger Delta.
