Popis: The amount of waste that enters the Kodungaiyur dumping ground, in Tamil Nadu, India increases day by day due to the urban sprawl and growth of the metropolitan limits. The leachate infiltration in the groundwater accounts for the contamination and it is a critical issue to be addressed. The survey conducted among the residents of Kodungaiyur represents a disagreement on the water quality among the residents of their area. The go-to rack and ruin health condition of the people in the locality makes them prone to frequent hospitalisations. Physico-chemical parameters from 12 bore wells around the dumpsite are tested. On average, the conductivity, Total hardness, Chlorides, COD, BOD, Total Dissolved Solids, Calcium, Magnesium, Sodium, Potassium and Total alkalinity are more than the BIS prescribed limits of drinking water standards. On analyzing the water quality index (WQI) using the weighted arithmetic method, it is clear that all the bore wells have a WQI of more than 100, which is the deprecatory indicator for the category of “Totally unsuitable for drinking”. The worrisome situation indicates that the groundwater is polluted and unsuitable for drinking and domestic purposes. The WQI has negatively correlated to pH as the pH of all the samples has values ranging between 6.5-8.5. Also, the WQI is high-positively correlated to Chlorides, Sulphates, COD, BOD, Total hardness, Calcium, Magnesium, Alkalinity, Nitrate and Sodium with a correlation factor of more than 0.900. This indicates the excessive presence of physical, chemical and biological parameters contributing to high values of WQI in the water samples. After evaluating the data, it can be concluded that the drinking water of Kodungaiyur is not potable and a direct demand to revamp the groundwater status in this region is the need of the hour to prevent the population from facing adverse health effects.
