Drinking water is a basic need of all living organisms. Pollution of water resource has slowly diminished the amount of clean water from our planet. The rapid urbanisation and growth of population further added the problem. Huge amount of solid waste generated from the residences, hospitals etc. is dumped in open land areas. Such dumping causes environmental pollution by deteriorating the ground water quality. The present study was done at Sewapura MSW dumpsite near jaipur to assess the ground water quality in and around the study area. The results reveal that high amount of Fluoride (2.4 - 3.2 mg/l). Chlorides (288.4 – 1038.2 mg/l) and TDS (610.4 – 1828.4 mg/l) are present in the studied samples which are of higher range of acceptable limits. The ground water in the study area is being polluted by percolation of toxic substances into it. MSW dumping in the open area should be prohibited by the authorities to control the further pollution of water.
