The importance of fresh water bodies is well known. Man’s greed for luxury and comfort resulted in the rapid deterioration of the environment. The water bodies from time immemorial had an aesthetic look, quenching the thirst of millions of people have today been loaded with toxic material and chemicals, which have rendered them almost useless. Sporadic reports have covered some of the famous lakes and tanks. However there are several lakes and tanks which have escaped the public eye. The biological wealth of a lake is mainly dependent on its water quality. The chemical nature of pollutants and sediments entering into the system from various sources is the major problem of medium and minor lakes located in several parts of India. This study highlights the quality of water analysed with reference to various physico-chemical parameters in selected lakes of Bengaluru North, of Karnataka state before and after the immersion of Ganesha idols. The major ions present in the lake water have been analysed. The lakes are found to be under the influence of parameters like temperature, pH, chloride, fluoride, Total dissolved solids (TDS), total hardness, alkalinity, potassium, sodium, calcium and magnesium. In many samples, two or more parameters have been reported above the permissible limit of drinking water.
