ASSESSMENT OF GROUND WATER SAMPLES FOR PHYSICO-CHEMICAL PARAMETERS FROM VARIOUS AREAS OF REWARI (HARYANA)

Due to human and industrial activities, ground water is contaminated. The present paper deals with the Assessment of ground water samples for Physico-chemical parameters from various areas of district Rewari (Haryana). The following 15parameters have been considered viz. Total Hardness, pH, Electrical Conductivity, Total Dissolved Solids, Alkalinity, Fluoride, Chloride, Sulphate, Nitrate, Phosphate, Lead, Zinc, Iron, Cadmium and Dissolved Oxygen by various analytical techniques. On comparing the results against drinking quality standards laid by IS-10500:1991 BIS, it was found that some of the water quality parameters were above the permissible limit and some were not. Alkalinity and Total Dissolved Solids levels are found extremely higher than permissible limits. High level of TDS and alkalinity causes objectionable taste and laxative effect. The most of the samples do not contain the concentration of Lead
