  Abstract: The study assesses four Wells’ groundwater quality in terms of its suitability for agricultural irrigation and drinking purposes. From January to December 2024, the following physicochemical parameters pH, turbidity, electrical conductivity (EC), total dissolved solids (TDS), ammonia, nitrate, fluoride, and chromium were examined. To evaluate each Well’s overall water quality, the water quality index (WQI) was computed. Well two (90.56) and Well three (71.14) WQI values show that the water …
