The motivation behind this exploration is to assess the groundwater quality in Dindugal area of Tamil Nadu based on the water quality list by geographic data framework (GIS) and measurable investigation. This region comprises of 80 utilitarian tanneries around Dindigul town with an ability to process about 200 Mt of covers up and skins as calfskin. In 13 towns, the same number of as 1090 houses were harmed by tannery defilement. A sum of 25 groundwater tests were gathered to distinguish the geochemical sources and defilement. In addition, Gibbs plots shown that groundwater tainting was gotten from the weathering of granitic gneisses and also the filtering of vanished and solidified particles from rural and mechanical effluents.
The water quality record (WQI) showed 8% of the groundwater tests were not appropriate for drinking reason. The GIS maps demonstrated that the poor water quality diminished at the southern piece of the examination territory. WQI of TDS, fluoride, sodium, potassium, and bicarbonate were high in groundwater. Multivariate factual examinations (important segment examination (PCA), factor investigation (FA)) proposed that the groundwater science was changed by the weathering of source rocks particle trade and draining of inorganic parts and expansion from anthropogenic effluents. At long last, it is believed that the observing and appraisal works are extremely valuable to comprehend the degree and wellsprings of groundwater defilement.
