【 摘 要 】

Groundwater contamination has become so alarming that the existing valuable freshwater resources are at stake. Landfilling of solid refuse without pre-emptive measures, over the years, leads to the utter depletion of the groundwater quality in its vicinity. The Kodungaiyur landfill at the Perambur taluk located in the northernmost region of the Chennai metropolitan, is such a poorly managed landfill. This research article is intended to exhibit a detailed study report on the physicochemical and bacteriological parametric analyses of the currently available subsurface water in and around the landfill area. Besides being evident from the faecal coliform test that the water is not potable, the chief objective was to investigate the suitability of groundwater for irrigation. Representative samples of groundwater were collected from inside the landfill site, and the residential areas located within 2 km from the site and analysed using standard methods. The test results were interpreted by employing exhaustive statistical approaches. It is evident to the interpretations that, out of the nine sampled locations, seven were found to be endowed with a groundwater quality fit enough for irrigation.
