ABSTRACT

Devarahalli tank is situated in Bhadravathi town of Karnataka. Water chemistry of Devarahalli tank is studied in the current article. Water samples were collected during January to December 2016 and analyzed for various physical and chemical parameters seasonally. It was observed that water quality of Devarahalli tank is polluted by sewage from the intensively surrounding catchments. Devarahalli tank is extensively used for washing, bathing, and for conducting religious rituals, idol immersion which showed eutrophication. Hence, the study was undertaken to find out the quality of tank water for various physico-chemical parameters. This water body is found to be organically polluted and greater degree of eutrophication was observed. The present article describes information of human activities on tank, and suggests some measures for restoration of this tank. The predicted water quality parameters were compared with the WHO and BIS standards. Keywords: Agricultural runoff, Water quality, eutrophication, sewage, restoration
