Devang Gandhi

In order to determine the water quality of Gunsa village water sources seven numbers of sample were collected from open well and bore well water sources. Water samples were collected from Shivpada, Karbharipada and Sawarpada locations and analyzed for the parameters of pH, Color, TDS, Turbidity, Total Hardness, Total Alkalinity, Chloride, Sulphate, Nitrate, Calcium, Magnesium, Iron, Zinc, Fluoride, E.Coli, and Total coliform bacteria. Weighted arithmetic index method was applied for determination of WQI. WQI was calculated on the basis of chemical test parameters, evaluated WQI was 119.2 (Unsuitable for drinking), 51.54 (Poor water Quality), 20.6 (Excellent water quality), 63.9 (Poor water Quality), 60.1 (Poor water quality), 33.5 (Good water quality) and 83.4 (very poor water Quality) for the location of 1 to 7 respectively. Biological test parameters found positive in all the samples hence, it is recommended to establish a water treatment facility at Gunsa village to increase the water quality and make it suitable for drinking purpose.
