Determination of Physico-Chemical Parameters of Surface Water Sample from Lohegoan Lake

The present study was undertaken to study the physico-chemical parameters of water samples collected from Lohegoan lake. The physicochemical parameter like, temperature, pH, total dissolved solids (TDS), turbidity, dissolved oxygen (DO), total alkalinity (TA), total hardness (TH), calcium (Ca++) magnesium (Mg++), sodium (Na+), potassium (K+), chloride (Cl-), was determined. The results were compared with standards prescribed by WHO (1973). It was found that the water samples collected from March 2011-Feb 2012 showed contamination. All sample showed physicochemical parameters above the water quality standards (expect in the month of June-August) and the quality of water is very bad and it is unfit for drinking purpose. The reason behind this contamination is the human interference and the use of water for washing clothes and vehicle inspite the area being less populated compared to the other part of Pune city.
