ABSTRACT

 

All the surface water resources (river, pond and lakes) are getting indiscriminately polluted in India as well elsewhere. The present investigation highlights the adverse impacts of water quality of Sengar river (India) due to the discharge of effluent of a petrochemical plant. During summer season, the downstream water quality was significantly changed due to lean flow that tends to alter ecological niche, aquatic flora and fauna, benthos, other aquatic organisms and self purification of the river system. The objective of this investigation was to assess the impact of the petrochemical industry effluent on water quality of Sengar River near Phaphund, Auraiya, U.P. The Physico-chemical parameters viz pH, Dissolved oxygen, Biochemical Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids, Sulphide and Oil and Grease were tested for three seasons. During summer season, the downstream water quality was significantly changed due to lean flow that tends to alter ecological niche and self purification of the river system. The downstream water was also unfit for bathing and potable that could be categorized as E Class of water used for irrigation, industrial cooling and control waste disposal.
