Ground water samples were collected from different locations in the radius of 25 km. of Surat city, Gujarat(India). These samples of ground water from 12 sampling point of Surat for their physico-chemical studies were tested. Laboratory tests were performed for the analysis of samples for pH, Colour, Odour, Hardness, Chloride, Alkalinity, COD, Sulfate, TDS, SS, Fe, Cu, Boron and Chromium. On comparing the results against drinking water quality standards laid by Indian Council of Medical Research (ICMR) and World Health Organization (WHO), it is found that most of the water samples are non-potable for human being due to high concentration of one or the other parameter. Most of the samples have Total Alkalinity, Hardness, Chloride and TDS values much higher than the permissible level stipulated by ICMR and WHO. The high values of these parameters may have health implications and therefore these need attention.
