Water plays a vital role in the development of activities in an area. Due to over exploitation, the water table falls too below the ground surface leading the people to go for confined aquifer. But groundwater resources also get contaminated due to discharge of sewage and solid wastes. Keeping this in view, the present study has been attempted to delineate contaminated groundwater zones in the Mangadu area. Open well water samples have been collected. Chemical analysis was carried out and the concentration levels of various chemical parameters were determined. The values of different physicochemical parameters for the entire study area were obtained by using Inverse Distance Weighted (IDW) interpolation technique through ArcGIS 10.1 software. The temporal variation of various chemical parameters over the study area is plotted. The map shows that water quality index at eastern region is little lowered compared to the western region. This is due to the water stagnation and inhabited area in western low areas by which water been started to contamination. Specifically individual parameter analysis shows that chlorine and hardness is slightly more in the northern region due to the nearest factory. In the central agricultural area due to fertilizers and other mineral implementation potassium and iron is slightly more compared to other areas. Overall the parameters are within limits and can be used for domestic purposes.
