Abstract: It's important to learn more about water sources to figure out how likely they are to get dirty. The study looked at the Mahanadi Basin. Twenty-one samples of groundwater were taken at the beginning and end of the wet seasons. The amount of pH, EC, Cl⁻, SO₄²⁻, Ca²⁺, Mg²⁺, HCO₃⁻, TH, Na²⁺, and K⁺ was checked. The water quality index (WQI) showed that 5% of the samples taken before and after it rained were not safe to drink. To see if the area was good for growth, sodium adsorption ratio (SAR), monster hunter rise (MHR), residual sodium carbonate (RSC), %Na, and Kelley's measure were used. 29% (MHR) and 71% (RSC) do not like it when it rains. Correlation matrices, box plots, Gibbs plots, Piper plots, and Wilcox plots were all used to show that the WQI was the same in every way, even in terms of how it worked chemically and physically.

Keywords: water; groundwater pollution; WQI; water quality index; human health risk assessment.
