The present work is to assess the contamination using hydro-chemistry by adopting multivariate statistical techniques. The water quality data collected during Sept 2019- Aug 2020 from twenty five sampling locations distributed in and around the Hospet Taluk. Total dissolved solid indicates deviation from 355 mg/L to 918 mg/L with maximum values noticed, as EC, in the selected ground water samples. The relative richness of cations in ground-water during the study period is Ca++>Mg++>Na+>K+. Maximum sulphate content is captured in the selected ground water samples with values exceeding the permissible limit of WHO. Sulphate is suspected of devising an anthropogenic source. The relative richness of anions in and around ground water samples of Hospet Taluk is in the following order: HCO3-> SO-24--> Cl-> NO3-. Author recommended the appraisal and monitoring the water quality during repair of pipes particularly in the area which is limit un-wanted infiltration. Authors also recommend for management of anthropogenic activities in and around the Hospet Taluk. USSL graphs predicts most of the ground water samples falls in C2-S1 class, which representing its suitable condition for drinking and irrigation needs. Piper trilinear graph confirms that the bore-wells were categorized as secondary alkalinity during the study period.
