Ground water samples in and around from the dumpsite located in Pallavaram were studied to assess the impact of Municipal solid waste on ground water resources in the particular area. Ground water samples were collected from the 5 different bore-wells in and around the dumpsites. The water samples in all 5 locations have mild to high iron concentrations and mild to high acidity. The high acidity in some of the water samples is related to products of anaerobic decomposition of waste while the high iron concentration noticed in most samples which are higher than Indian Standards limit of 1.0 mg L^-1 can be attributed to the location of such bore-wells close to such source as dumpsites. The presence of such dumpsites therefore is a potential source of pollution to the ground water.
