IMPACT OF IMPROPER DISPOSAL OF MUNICIPAL SOLID WASTE ON GROUND WATER QUALITY IN AND AROUND THE SOLID WASTE DUMPING SITE OF VISAKHAPATNAM, ANDRAPRADESH, INDIA
The physiochemical analysis of groundwater in the environs of dumping yard, Visakhapatnam district, Andhra Pradesh have been carried out in order to access suitability of water for drinking and irrigation purposes. The improper disposal of municipal solid waste causes deterioration of water quality in and around waste disposal sites. The toxic contaminants of municipal solid waste reached in shallow and deep aquifers though leaching. The methodology consist of field survey, collection of ground water samples and analysis of physiochemical parameters of water quality. The physiochemical data were compared with Bureau of Indian Standard (IS: 10500, 2012) of drinking water quality. Totally 11 water samples were collected at dumping yard and areas around dumping yard within 5 km radius during March 2016. The result showed that the measured parameter conductivity, TDS, Cl, total hardness, SO4, NO3, F, Na, K have crossed maximum permissible limit prescribed by Bureau of Indian Standards BIS standard for drinking water quality and this indicated ground water quality has been severely contaminated due to improper disposal of municipal solid waste.
