Remote Sensing and GIS Techniques for Monitoring Water Quality of River Ganga at Its Origin to Rishikesh
Abstract
We used physiochemical and biological parameters to assess the water quality of holy river Ganga in
Uttarakhand. The monitoring was conducted three times in the year (2015-2016) during the different seasons.
Water samples were collected from Gangotri and Rishikesh followed by the course of river site of ongoing
Hydroelectric project, industrial and Urban areas. The monitoring techniques (remote sensing technology and
GIS) were used to store and retrieve the information about the management of river for long distances around
the sites. The assessment of different physiochemical parameters (pH, EC, DO, BOD, COD, cation anion and
heavy metal) indicates that the water quality of river Ganga is classified good to moderate. Contrarily the total
bacterial count and differential membrane filter methods have been used to assess the estimation of microbial
concentration in the industrial and transport areas
