physicochemical parameters

ABSTRACTGround water quality and its impact on human health in an industrial area near Tirupati, India has been assessed. Water samples were collected from 40 different locations of Vadamala Pet near Tirupati and analyzed for physicochemical parameters such as pH, electrical conductivity, total dissolved solids, total hardness, calcium, chlorides, sulphates, nitrates and dissolved oxygen etc. The found values of physicochemical parameters were compared with the World Health Organization (WHO) water quality standards. Based on the physico-chemical analysis and correlation studies, it was found that ground water of some of the studied areas was polluted and not suitable for drinking purpose. Thus the ground water of such areas needs purification before drinking. Keywords: Ground water, physicochemical parameters, purification, total dissolved solids, hardness.
