Study on Physico-Chemical Parameters of Water Samples Collected from Palair Lake, Khammam, Telangana, India

Abstract

Water is one of the most abundant compounds and comes in a variety of forms. Lakes are vital lentic freshwater habitats, with water quality influenced by a variety of environmental and seasonal factors. The purpose of this study was to examine the physico-chemical parameters of Palair Lake. Water samples were obtained at three stations for this study between June 2013 and May 2015. The range of physico-chemical parameters were observed Temperature (21.2°C to 25.6°C) 0C, pH (7.2 to 8.3), CO₃^-2 (16.56 to 40.68) mg/l, HCO₃^- (237.26 to 267.56) mg/l , Cl^- (118.25 to 147.98) mg/l, DO (7.1 to 11.2) mg/l, BOD (15 to 30) mg/l, COD (16.2 to 36.11) mg/l, T.H (60.03 to 84.44) mg/l, Ca⁺⁺ (31.46 to 55.65) mg/l ,Mg⁺⁺ (18.16 to 37.26) mg/l, SO₄^-2 (24 to 42) mg/l, PO₄^-3 (0.52 to 0.94) mg/l, NO^3-(0.56 to 0.88) mg/l, T.S (119 to 198) mg/l, T.D.S (88.69 to 119.5) mg/l during the study. The analysed result is compared to WHO and BIS permitted limits for drinking water quality. Temperature, pH, dissolved oxygen, biological oxygen demand, chemical oxygen demand, calcium, and hardness were found to be within WHO and BIS guidelines. The findings show that the water is safe for recreational and household use, but human activities surrounding the lake must be regulated to ensure long-term use and preserve the lake's beauty.
