Abstract: | The study aimed at determining the socio-economic issues due to municipal solid waste dumping, the extent of groundwater contamination and the groundwater dependency around Perungudi dumpsite in Tamil Nadu, India. Sampling and analysis of groundwater and leachate show the contamination migration is due to dumpsite leachate. The concentrations of contaminants were more severe within 1.5?km along groundwater flow direction mainly due to the geological profile. The Piper diagram also shows that the groundwater sampled within 3?km in the flow direction was classified as Na–Cl type. Studies conducted within contaminated areas to determine the groundwater usage showed that higher percentage of lower and middle socio-economic status categories was using the groundwater for domestic purposes, which may lead to health issues. The present study suggests that proper solid waste management and groundwater remediation techniques along with the people’s involvement are necessary to reduce the consequences of groundwater contamination on the people residing around the dumpsite. |
