The good quality availability of water for human consumption is very important for preventing waterborne diseases and improving the quality of life. This work presents the study of the physico- chemical properties of water samples collected in and around the mining areas. Some of the parameters like EC, TDS, Total hardness, magnesium, sodium, and iron content are greater than the permissible value in a few areas. The analyzed parameters were compared with the WHO standards. Dissolved Oxygen and total hardness ranged from 7.8 to 8.9 mg/L and 102 to 1500 mg/L in both Tummalapalle and Mangampeta samples.</p></abstract><kwd-group><title>Keywords</title><kwd>Mining areas</kwd><kwd> Population</kwd><kwd> Parameters</kwd><kwd> Total Hardness</kwd><kwd> Water quality</kwd></kwd-group><counts><ref-count count='' /><page-count count='' /></counts></article-meta></front></article>
