A Study on Ground Water Chemistry and Water Quality Index from Tamil Nadu District of Karur

Abstract

In this study, we investigated the chemical properties of groundwater and drinking water and collected 10 groundwater samples in Karur district at the start of the 2019 monsoon. Water samples were then analyzed to determine pH, electrical conductivity, total dissolved solids, bicarbonate, chloride, sulfate, calcium, magnesium, sodium and potassium. Results were assessed and compared to WHO and BIS water quality standards. Research results reveal that groundwater is cool to brackish and moderately to moderately high in nature. Na and Cl are the dominant ions between cations and anions. Chlorides, calcium and magnesium ions are within acceptable limits, with the exception of a small number of samples. Based on WQI results from 10 samples, 20% of samples showed good water department, 80% of samples were from excellent water department.  The majority of samples are classified from excellent to good categories and are suitable for drinking water purposes.
