Fifteen (15) dug well ground water samples (represented by S-1 to S-15) were collected during pre-monsoon period (March) of 2018. They were analyzed for physico-chemical parameters such as temperature, pH, TDS (total dissolved solids), electrical conductivity (EC), total alkalinity (TA) (and hence CO and HCO ), total hardness (TH), Ca2+, Mg2+, Na+, K+ and Cl-. All the values/concentrations of the above different physicochemical parameters for the fifteen ground waters, were found to be below / within acceptable limits of BIS standard for drinking water as well as that of WHO. So, all the ground waters are found to be fit for drinking purpose. Further, as the TDS values for all the fifteen ground waters were found to be less than 1000 mg/L, such ground waters are also suitable for other domestic purposes. In addition to this, all these ground waters are also found to be suitable for irrigation (agriculture) purpose as their % Na (percent sodium), RSC (residual sodium carbonate) and SAR (sodium adsorption ratio) values are within the categories of excellent / good category of water for irrigation purpose.
