Water pollution is caused by industries as well as other activities etc. Research findings indicate that application of heavy doses pollute ground water through leaching of nitrate from fertilizers and metals like cadmium from single superphosphate and of fluoride from phosphate rocks. Heavy metals such as lead, mercury, arsenic, aluminum, copper, nickel, tin and antimony deteriorate water quality to a large extent. This paper deals with the analysis of heavy metalsCu, Cr, Fe Mn and Zn in surface and ground waters for a period of 6 months from eight sampling stations in the vicinity of Jindal Ferro Alloys corporation , Visakhapatnam Dt.(A.P.) The estimated metal levels in the water samples were compared with those limits laid down by WHO standards. It was found that concentration of some metals such as Fe and Cr above the permissible levels in summer probably due to seasonal variation.
