A study of ground water of industrial zone of Moradabad in Uttar Pradesh has been carried out to examine quality of water for drinking purposes. The samples were collected from bore wells, tubewells, hand pumps and jet pumps. The data was analyzed for various physico-chemical parameters.

Microbial load in the groundwater and the physico-chemical characteristics of the water samples in and around the dumpsite of Dindigul town, Tamil Nadu, was studied. A microbial analysis of the leachate of the municipal solid waste, the ground water collected from the dumping yard and the ground water collected from a distance of 100 feet away from the dumping yard was also carried out to find out the effect of the municipal solid waste on the ground water quality.

Geographic Information System (GIS) was utilized to apply a modified DRASTIC method to assess the aquifer vulnerability to pollution of English Bazar Block of Malda District, West Bengal, India. In the western, central and southern parts of the study area the aquifer is prone to contamination. Therefore, in these regions pesticides, which may contain arsenic or arsenic rich groundwater, should not be used in irrigated land or mango orchards. In order to understand the reliability of the aquifer vulnerability, sensitivity analysis was carried out.
