Spatial and temporal variations in water quality, major ions and trace metals

Abstract

Godavari river at Rajahmundry is monitored for a period of seven months at five stations along its course for the physicochemical parameters, major ions and trace metals. This study is made to obtain a baseline data of the existing pollutants in this 'hotspot', which is set to become the industrial hub of Andhra Pradesh. Results indicate that A P Paper Mills may not be polluting the river at this period, contrary to what was expected. Clear picture will emerge, once the data for the rainy season is available. Local pollution from detergents and soap in the river is seen in the downstream (station VIP) as lot of bathing and washing activity is done on the banks. There is no pollution of Cu, Ni, Pb, As and Co in the Godavari river at Rajahmundry. In general the pollutant levels in all the stations analysed is within the prescribed limits set by BIS and WHO standards. Copyright Enviromedia.
