Water Quality Assessment of the Mahananda River in Sub-Himalayan Foothills Regions of India

Abstract

The Physico-chemical characteristics were supported by a recent study determining the quality of water in the Mahananda River. While assessing water quality, pH, dissolved oxygen (DO), temperature, biological oxygen demand (BOD), nitrate, fecal coliform, total coliform, and conductivity were taken into account. Samples were taken from three distinct locations along the river, and temporal data was collected from 2009 to 2016 to be analyzed using various statistical approaches. The majority of the parameters in our analysis surpassed the highest allowed standard value set by the CPCB. Especially the people of Siliguri are mostly captivated by river Mahananda to meet their needs for drinking and numerous household uses regularly, but the river's state is currently very poor due to several water pollution problems. The Physico-chemical properties of the Mahananda River are Miserable due to unpurified sewage, garbage, and rapid urbanization of the Siliguri municipal area. This glance gives a general overview of the present problems with water in the river adjacent area. This study may be the simplest way to communicate with the people and the policymakers.
