Studies of Selected Water Quality Parameters of River Ganges at Patna, Bihar
Keywords:Electrical conductivity, Alkalinity, Total Solids, Hardness, Chloride, Dissolved Oxygen, Biological Oxygen Demand, Most Probable Number
The study was carried out for a period of only two seasons (Pre-monsoon and Post-monsoon) in a year. The physicochemical parameters such as pH, Electrical conductivity (EC), Alkalinity, Total Solids (TS), Hardness, Chloride, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD) & Most Probable Number (MPN) were evaluated at selected sites of River Ganga. The river is subjected to severe domestic and sewage pollution at two selected sites of Patna. At sampling site, I and II physicochemical parameters were not found to be within the safe limits of drinking water as World Health Organization WHO (1984). But at sampling site II chloride were found within the safe limits. At sites, I & II water sample was not found good quality showing that the River Ganga has moderately polluted. The present studies indicate that increase water pollution levels in the River Ganga present near urban environment due to discharge of various types of wastewater/ sewage/ effluents.
