An Investigation of groundwater quality for drinking purposes using hydro-chemical parameters in and around Sandur Taluka, Bellary District, India

Abstract

The destruction of groundwater quantity and quality due to anthropogenic activities is increasing atdistressing rate in most portions of the northern Karnataka Sandur taluka. Limited research works have been carried out on the ground water quality and analysis. In the present paper highlighted on the ground water quality and compare the quality with respect to drinking and agricultural purposes in the Sandur region a northern part of Karnataka. In Sandur region most of the formers are depending upon the ground for drinking and agricultural practices also they are using pesticides and fertilizers. The summary of the analytical results and the statistical measures such as minimum, maximum, mean and standard deviation are also discussed for March 2015 and February 2017. Total fifty ground water samples were collected and analysed for all cations, anions and other physicochemical parameters. Analytical results are compared with the drinking and agricultural purposes. Results are indicated majority of the ground water samples were above the permissible limit of Indian standards. The groundwater of the Sandur region was very hard and the relative richness of major cations and anions. In the entire study period fluoride content was higher than permissible (1.0 mg/L) limit in 52 %. According to this study, the ground water in and around Sandur region all the water samples were supersaturated with respect to carbonate minerals, the present work concludes all most all the ground water samples were not suitable for drinking uses in the study area. Hence the authors are recommended to carry out continuous monitoring program and effective development management practices for utilization of most important a biotic natural resources.
