Ground water quality assessment of Dhankawadi ward of Pune by using GIS

This paper aims to assess and map the spatial distribution of ground water quality of the Dhankawadi ward of Pune by using the Geographical Information System (GIS). Dhankawadi is experiencing rapid urbanization, this made people to depend on groundwater resources. APHA's standard laboratory procedure has been adopted to assess the quality of ground water at each sampling location. Garmin GPS has been used to collect the sampling point location. Inverse Distance Weighed (IDW) spatial interpolation technique has been used to estimate the spatial distribution of the ground water parameters and WQI. A potable index map has been prepared with help of WQI map. Google earth has been used for preparation of Land use and Land class (LULC) image. Results of WQI are interpreted with respect to the LULC. The potable Index map shows that, the groundwater in the study area is good enough for drinking and domestic purposes except in the places of Upper Katraj nagar and north part of Bharati Vidyapeeth University campus.
