Abstract

A study of surface water of Sanbarish pond has been carried out to examine the quality for drinking and other domestic purpose as well as to evaluate the water pollution status of wetland on the basis of the presence of different physicochemical and microbiological parameters. For calculating the WQI, the following 11 parameters have been considered: Temperature (ambient and water), pH, turbidity, TDS (Total Dissolved Solid), Cl- (chloride), EC (Electric Conductivity), DO (Dissolved Oxygen), TH (Total Hardness), PO4–P (Phosphate – phosphorus), NO3-N (Nitrate – nitrogen), COD (Chemical Oxygen Demand).  The WQI for these samples has been found to be mainly from the higher values of turbidity, DO and PH of the wetland water. The result of WQI has indicated the calculated value (?SIi = 95.59) showed the good quality for drinking as per the classification given and needs some proper treatment before consumption, and it also needs to be protected from the risk of contamination. The mean value of fecal coli form recorded was 1166.67 MPN/l00 ml which was crossed the WHO guide line.
