ASSESSMENT OF GROUNDWATER QUALITY AND STATISTICAL ANALYSIS OF HYDRO CHEMICAL PARAMETERS IN CUTTACK CITY, ODISHA, INDIASANJAYA KUMAR MUDULI, NARASIMHAM MANGALAMPALLI AND PRAKASH CHANDRA MISHRA
In this study, a total of 25 number of groundwater samples were collected from different parts of the Silver City Cuttack, Odisha to analyze the hydro geochemical parameters. The water quality parameters such as pH, Turbidity, Electrical Conductivity, Total Dissolved Solids, BOD, Fluoride, Chloride, Nitrate, Sulphate, Total Alkalinity, Calcium, Magnesium, Iron, Sodium, Potassium, Lead, Copper, Cadmium, Nickel, Chromium and Fecal Coli form were analyzed. Out of the total 25 sampling locations, the WQI of 10 locations were found to be poor and 2 locations were found to be unsafe for drinking. Turbidity of 24.6 NTU was found at location S-10 (Haripur road) and TDS value of 688 mg/l was found at the location S-20 (Buxibazar).The iron concentration of 8237.3 Î¼g/l was found at the site S-16 (Dolamundei), Lead concentration of 6.6 Î¼g/l was found at the site SS- 16 (Dolamundei) and Cr concentration of 42.2Î¼g/l was found at the site S-4 (Khan Nagar industrial area). The maximum MPN value counted 58.7 in each 100 ml sample at the location site S-12 (Chhatra bazaar). The seasonal parameter variation was found higher in summer which indicates depletion of groundwater level which leads to enhance the level of contamination. The anthropogenic activates, i.e. discharging of industrial waste to the surface body and flows of untreated sewage effluent by unprotected drainage throughout the city accelerate the deterioration of ground water. The Fecal Coliform present in bore well both in summer and rainy season indicates that water logging and poor sanitary sealing of ground drinking water sources. The day by day increasing of NO3 concentration in ground water indicated the influence of sewage in the ground water quality. Increasing in concentration of metals such as Pb, Ni, Cr in the ground water in summer season creates an alarming situation for the consumption of drinking water.
