Abstract

In the present study, various physico-chemical factors were assessed for the whole year (Jan 2009-Dec 2010), to determine the impact of domestic sewage and industrial effluents on the water quality of the Khan river. Physico-chemical factors like pH, temperature, conductivity, ammonia, nitrate, nitrite, sulphate, phosphate, total hardness, calcium hardness, chloride, BOD, COD, Ca, Na and K were found with maximum concentration during premonsoon. While, concentration of total solids, total suspended solids and DO was maximum during monsoon. The positive correlation was observed among all the physico-chemical factors except DO. The study reveals that the huge influx of domestic sewage and industrial effluent are the key factors enhancing pollution load in the Khan River.
