Abstract
In this study, we gathered ten groundwater samples in Karur district at the beginning of the 2019 monsoon season in order to examine the chemical characteristics of drinking water and groundwater. After that, pH, electrical conductivity, bicarbonate, chloride, sulfate, calcium, magnesium, sodium, and potassium were measured in water samples. The outcomes were evaluated and contrasted with the water quality standards set by the BIS and WHO. The findings of the study indicate that the type of groundwater is moderately to fairly high and cold to brackish. The two most prevalent ions among cations and anions are Na and Cl. The levels of calcium, magnesium, and chlorides are within permissible bounds, except for a few samples. According to WQI results from ten samples, the water department was good in 20% of samples and exceptional in 80% of samples. Most samples are suitable for use as drinking water and fall into the excellentto- good category.
