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.

Abstract: The persistence of low density polyethylene (LDPE) in municipal dumping sites represents a major environmental concern due to its non-biodegradable nature. The present investigation aimed to isolate, characterize, and genetically identify indigenous LDPE-degrading bacteria from the municipal dumping site of Himmatnagar, District Sabarkantha, Gujarat, India. Soil samples collected from plastic-contaminated zones were subjected to enrichment techniques using LDPE as the sole carbon source. Efficient bacterial isolates were screened based on growth performance and percentage weight loss of LDPE films. Morphological, biochemical, and physiological characterization was carried out to evaluate the biodegradation potential of the isolates. Structural and chemical modifications in LDPE films following bacterial treatment were analyzed using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). SEM analysis revealed surface alterations such as cracks, pits, and erosion on LDPE films, indicating microbial action, while FTIR spectra showed significant changes in functional groups, including the appearance of carbonyl and hydroxyl peaks, confirming polymer oxidation and degradation. Molecular identification of potent isolates was performed through 16S rRNA gene sequencing and phylogenetic analysis. The study demonstrates that indigenous bacterial strains from municipal dumping sites possess substantial LDPE-degrading capability and highlights their potential application in sustainable bioremediation and plastic waste management strategies.
