The concentration of Seven heavy metals (copper, Cadmium, iron, chromium, manganese, lead and zinc) have been evaluated at twenty important ground water sampling stations at Dhanbad town for three seasons of the year. The concentration of heavy metals in general was found to be below the permissible levels although concentration of iron and manganese was found above the permissible limits at a few stations. These data have were for the calculation of Heavy Metal Pollution Index (HPI). The HPI of ground water was found to be far below the index limit of 100 pointing to the fact that the ground water was not polluted with respect of heavy metals in spite of the prolific growth of mining and allied industrial activities near the town.
