The lake receives domestic waste from Khanpura village and its adjoining areas. People living near the lake use it for irrigation purpose while cattle use water for drinking and bathing. They frequently suffer from water borne disease. The lake water contains high values of TDS, BOD, COD, alkalinity, hardness and chloride which are beyond safe limits indicating severe degradation of water quality. The present investigation reveals a specific pattern in diurnal changes of physicochemical parameters. Several measures are also suggested for the removal of pollutants. The study was carried out in each season and per day at an interval of four hours. A suitable correlation was also established between degradation index and environmental protection cost which may be used as regulating measures for preserving perennial and seasonal wetlands of Ajmer. This paper is an attempt to understand the impact of climate change on water resources and identifies general and specific impacts related to different physicochemical parameters.
