Physiochemical Analysis of Sewage Fed Water in Gandak River in Vaishali District near Hajipur

Abstract

The Gandak River, also known as the Narayani and the Gandak is one of the Major River in Nepal and left bank tributary of Ganga in India. Hajipur city, west central Bihar state, northeastern India. It lies on the Gandak River just north of its confluence with the Ganges (Ganga River). The city is in the North Bihar Plains, which are part of the Middle Ganges Plain. The Gandak River has a total drainage basin area of 29750 sq kms. The River flows through the Indian states of Bihar and U.P, and joins the Ganges near Patna just downstream of Hajipur. During the investigation, the researcher tried to find out the Physio-chemical Analysis of water across two year. Four sampling sites were selected located at the bank of Gandak River at Hajipur, Vaishali, Bihar. In this study, various analytical techniques were used to study the water quality parameters like BOD, COD, DO, PH, TDS, Hardness, Chloride, Calcium and Magnesium. The findings of the present investigation reflect that most of the water quality parameters are within the acceptable limits in accordance with WHO standards.
