The results obtained are related to electrical conductivity, pH, Turbidity, Total Dissolved Solids, Total Hardness, Calcium and Magnesium Hardness, Chlorides, Alkalinity, Fluorides, Nitrites,  Phosphates, Phenol, Metals like Sodium, Potassium, Iron, Zinc, Cadmium, Cobalt, Nickel,Lead andCopper. Theresults obtained are compared with standards of WHO andBISand assessing the quality of ground water for drinking purposes through Water Quality Index (WQI). Finally, the results indicate that the water at Srikurmam is not fit for drinking without using a standard purification method.
