Slow poisoning of Indian reservoirs due to idol immersion: A case study of Laharpur reservoir, Bhopal

Abstract

Today the developmental activities and the occupancy in the area is exerting pressure on the water body. Surface water contains some degree of contamination and in country like India this increases due to some religious activities. The present study was conducted on Laharpur reservoir, Bhopal to access the pollution load due to such religious activities. During the course of study various parameters like DO, BOD COD, pH, turbidity, alkalinity, Nickel, Manganese, Chromium and Lead were observed during pre-immersion and post immersion of idols. It was found that there is little variation in physico-chemical parameters but the increasing load of heavy metals due to idol immersion is a serious problem for the reservoir.
