Online published on 31 December, 2022. Abstract The present study attempts to decode the subsurface water contamination with compare to seasonal variations in hydro-geochemistry of groundwater in the Parbhani tehsil of Maharashtra, India. The study are area is situated around Parbhani city is a part of Godawari-Purna sub basin located between 76036’ to 77059’ E and 19007’ to 19017’N. A total of 88 groundwater samples of post post-monsoon (POMS) and pre-monsoon (PRMS) seasonsns were collected and analyzed for major ion composition such as viz. pH, Ec, TDS, CO3, HCO3, Ca, Mg, Cl, Na, K, N, K, NO3, F and SO4 using standard analytical procedures of APHA. res of APHA. The finding of study is digitized using ArcGIS software, ERDAS imaging software, Landsat images along with survey of India's official toposheet. As compared to the WHO drinking standards, majority of groundwater samples are fit for drinking. Nonetheless, its noticed noticed that the higher concentration bicarbonate in subsurface ace water was found in upper catchment of the watershedhed in pre and post monsoon season on the other hand traces traces of fluoride contamination has been found in central part part of study area. The subsurface water bodies situated nearr Parbhani, Raipur and Balsa villages shows the concen concentration of calcium, magnesium, sodium and potassium above ove permissible limit possibly due to exceed use of fertilization for cultivation besides urbanization in the study area.
