Delineation of safe groundwater aquifers in a Fluoride contaminated region: Walwa Taluka, Maharashtra

Groundwater aquifer contamination has leads health problems in village areas of Maharashtra, India. In this study, groundwater analysis was carried out for different parameters along with fluoride to delineate the high and low contaminated region Walwa taluka, Maharashtra. A distinct regions F‒ were identified collected post monsoon samples (n = 144). total 98% are unsuitable consumption. Hydro-geochemistry showed highest anion concentration bicarbonate (1880 mg/L), whereas cation calcium measured as 118 mg/L. It is main cause alkaline condition region. The 2D ordinary kriging results well corborated obtained hydrogeochemistry results. found near Krishna River, agricultural land primary suggests that geogenic source minerals practice fertiliser, herbicides pesticides on field these secondary contamination. applied numerical modelling software, provided technically viable effective decision making-tool identification safe study area.
