Abstract: Major source of drinking water in the Patna region is ground water. This study focuses on assessing the impact of Municipal solid waste on ground water quality near around dumping site area in the Ramchak-Bairiya, Patna, Bihar, India. Dumping sites are in a risk zone of spilling of leachate through adjacent soil which leads to contaminated ground water. Surrounding area of dumping site can be a serious threat to the human health and environment. Huge quantity of municipal solid waste (MSW) dumps containing hazardous materials are a serious threat to the surrounding population of Patna. When these MSW are dumped at site, ground water began contaminating due to percolation of leachate to the porous ground surface. This leachate contains large number of contaminants which can pollute ground water. Ground water samples of different location adjacent to dumping sites were analyzed for microbiological, biochemical characterization, most probable number estimation and antibiotic sensitivity testing of isolated bacteria. The result of MPN test reveals heavy bacterial load in several sampling site which clearly indicates bacterial contamination inside source ground water. Presence of coliform confirms leachate infiltration into the ground water. Antibiotic susceptibility testing demonstrates a pattern of resistance against selective antibiotics. This may suggest the evolve of multidrug resistance (MDR) bacteria in contaminated ground water. Present investigation concludes that leachate of MSW from the Ramchak-Bairiya MSW dumping site severely contaminate the adjacent ground water quality, leading to serious Public health and environmental risks.
