Spatial distribution of ground water quality in some selected parts of Pune city, Maharashtra, India using GIS

Abstract

Pune is one of the major developing cities in India; its area is rapidly increasing as neighboring villages like Aundh, Baner, Pashan and Sutarvadi are merged into the Pune Municipal Corporation (PMC). Majority of the people are using the groundwater as a prime source for their domestic needs, besides the PMC is supplying them with an allocation of treated water. Assessing the quality of groundwater is an important issue in the modern times. Spatial variations in ground water quality in some selected parts of Pune Municipal Corporation, Maharashtra, India, have been studied using geographic information system (GIS) technique. 29 bore well water samples were collected representing the newly merged. The water samples were analyzed for physico-chemical parameters as prescribed by APHA, using standard techniques and compared with WHO (2006, 2008) drinking water quality standards (1, 2). The ground water quality information maps of the entire study area were prepared by GIS Inverse Distance Weighting (IDW) technique for all the above parameters. The results obtained in this study with the spatial database established in GIS will be helpful for monitoring and managing ground water quality and its pollution in the study area of Pune city
