Determination of heavy metals in tap water samples in Ekpan district of Warri, Delta State, Nigeria

The concentrations of Lead, Iron, zinc, Copper, Manganese and Tin was determined in Tap water samples in Ekpan district of Warri, Delta State, Nigeria. Samples were collected from six different sites each of industrial and residential areas of the district and were analyzed using Atomic Absorption Spectrophotometer (AAS). From the industrial location, Lead and Iron in samples S3 and S4 respectively were significantly (p<0.05) above the WHO limit for Lead and Iron in drinking water while only Manganese from sample S5 in residential areas was significantly (p<0.05) above the WHO limit for Manganese in drinking water. Tin was not dictated in all the samples collected from the industrial area while both Lead and Tin were absent in samples collected from the residential areas. The levels of Lead and Iron from the industrial areas of Ekpan district are above the WHO limits, indicating higher risk of Lead and Iron toxicities in this district.
