Gomti river originates from Madhoganj Tanda village in Pilibhit district, U.P. It passes through the district of Shahjahanpur, Kheri, Hardoi, Sitapur, Lucknow, Barabanki, Sultanpur, Jaunpur and ultimately merges in Ganga. The world is facing problems with a wide variety of pollutants both inorganic and organic in nautre. Healthy soil, clean water and air are the soul of life. Often soil, water and air are no longer clean and pure, but pose human health risks. Gomti receives huge quantities of untreated sewage, agricultural runoff, brings lot of pesticides, fertilizer, street washouts bringing oil, asphalt, sediment and many types of heavy metals. From industrial effluents to domestic discharge, the river becomes more of a flowing dumping yard. The physicochemical parameters in water of river Gomti were assessed to know about the water quality in its catchment area. Total of fifteen sampling sites were selected between Guaghat upstream and Gomti Barrage. Parameters like Temperature, Total suspended solids (TSS), Total dissolved solid (TDS), pH, Hardness, Dissolved oxygen (DO), Nitrate, Nitrite, Chlorine, Total Coliforms and some Heavy metals were determined. Changes in water quality of River Gomti due to variations in quantity of parameters were found. Heavy metals mainly Iron, Cadmium, Copper and Arsenic were noticed.
