Abstract
Four heavy metals (Copper, Cadmium, Lead and Zinc) are monitored in drinking water at twelve important residential areas using DPASV Technique. The results indicate the water to free of heavy metal pollution. The data monitored have been used to compute Heavy metal pollution index (HPI) using weighted arithmetic mean method and the proposed Pollution Index (HPI) seems to be applicable in the assesement of overall water quality with respect to heavy metal pollution.
