SEASONAL VARIATION ASSESSMENT IN PHYSICOCHEMICAL PARAMETERS OF NAKATIA RIVER, UTTAR PRADESH (INDIA)Deepti, Archana Bachheti, R.K. Bachheti and V.K. MishraAbstract The purpose of this study was to estimate the physical-chemical parameters and their variation across the stretch of the Nakatia river that flows through Bareilly comprising six sampling sites namely Mudiya Ahmadnagar, Harunagla, Mohanpur Nakatia, Thiriya Nijawat khan, Manpur Chikatiya and Ruriya. Data were analyzed on pH, TDS, alkalinity, chloride, total hardness, BOD, COD, nitrates, dissolved phosphates and heavy metals. The study found that pH, TDS, alkalinity, chloride, total hardness, COD, iron and nickel of the Nakatia River were found within the limits prescribed by BIS. However, at some sites, BOD, nitrate, dissolved phosphate and arsenic exceeded the permissible limit. Industrialization, urbanization, untreated waste and sewage disposal are some of the key indicators of pollution of the Nakatia river in Bareilly,Uttar Pradesh. |
