Ground water represents one of the most important water resources in India as it in the rest of the globe and account for over 400 km³ of the annual utilizable resource in the country. Reliance on ground water resources is particularly strong where dry season surface water levels or low wet season flows are too disruptive to be easily tapped. Many human activities are responsible for the pollution of groundwater, due to mixing of petroleum products, pesticides & herbicides heavy metals, toxic industrial & domestic wastages. Surplus organic material and contagious organism by percolation and infiltration into ground water resources. In the present study temperature, pH, EC, free CO2, Chloride, total alkalinity, total hardness, Ca-H, Mg-H, D.O., B.O.D., C.O.D., Nitrate, are analyzed at different sampling stations. this study is very significant worldwide to keep, close water on water quality.
