The emulsification of major constituents in groundwater is accentuated to highlight the impact that is anticipated to be the prime concern due to depleting quality of this resource used for drinking purpose. In view of this, 53 groundwater samples of dug wells taping basaltic water table aquifer located in Haveli taluka adjoining Pune city of Maharashtra, India were collected and analyzed for major cations and anions to evaluate the suitability using water quality index (WQI). The parameters such as pH, Total Hardness (TH), Sodium (Na) and Sulphate (SO4) were assigned with weight 5 and the weight 1 considered as lowest level was assigned to Calcium (Ca++), Magnesium (Mg++), Potassium (K+), Carbonate (CO3--), Bicarbonate (HCO3-) and Phosphate (PO4) and observations were made to know the groundwater quality of the study area. Using these values, the WQI was calculated that revealed according to BIS standards 57% of samples falls in good category, and 43% samples in poor category, while according to WHO standards 38%, 57%, 6% were representing excellent, good and poor category, respectively.

WQI method is used for evaluation of groundwater quality for drinking purpose.

The groundwater quality indexing is performed based on BIS and WHO standards.

Groundwater samples from dug wells taping basaltic water table located in Haveli taluka adjoining Pune city were collected and analysed for major cations and anions.

About 43% samples were reported in poor category according BIS standards.

About 38%, 57%, 6% samples were representing excellent, good and poor groundwater as per WHO standards, respectively.

Groundwater sample from agricultural land-use is a more contaminated due return flow of agriculture.
