EVALUATION OF PHYSICOCHEMICAL CHARACTERISTICS OF GOMTI RIVER WATER AT UTTAR PRADESH, INDIA.

The aim of the study is to find out the water quality of the Gomti River of Uttar Pradesh. River Gomti is an important River of Uttar Pradesh, originate from the FulhaarJheel present in Pilibhit region in Uttar Pradesh. The River goes for a distance of about 900 km, passing through Uttar Pradesh finally to join River Ganges in Ghazipur in the area of Saidpur. Different cities that are located along the banks of the River Gomti are Sultanpur, Lucknow, Jaunpur and these are the main cities that are prominent in the region, out of the total 15 cities in the catchment land. A total 10 parameters namely Temperature, pH, Total dissolved solids (TDS),Total hardness, Alkalinity, free CO2, Dissolved oxygen (DO), Biological oxygen demand (BOD), Chemical oxygen demand (COD) and Chlorides were analyzed and their seasonal variation is discussed to obtain the impact of effluents on water quality. The observed values of different physicochemical parameters were compared with standard values recommend by World Health Organization (WHO) and Bureau of Indian Standard (BIS).From the result it was found that the most of the parameters of Gomti River water are within the permissible limit of WHO and BIS but some parameters like pH, BOD and DO were found higher than the permissible limit of WHO and BIS.
