Water quality assessment of Ganga River at Varanasi city

Abstract

The Varanasi city’s sewage are discharged into river Ganga at about 32 major point Five sampling locations Tulsi Ghat, Rajendra Prasad Ghat, Varuna drain, Nagwa drain, Narayan Ghat was studied for physico-chemical and bacteriological properties such as Temperature, TDS, Turbidity, DO, BOD, FCC etc. An analysis of variance reveals significant variation in most of the parameter with respect to sites. The analysis shows that a higher concentration of sewage is discharged into river Ganga. Further more Nagwa drain and Varuna drain was having higher pollution load where as Tulsi Ghat has less concentration of different water quality parameter. The current study indicate that increase in water pollution levels in the river Ganga near urban environment is due to discharge of waste water/sewage and can help to select measures for improvement of water quality of the river Ganga.
