Report on waste dump sites around Bangalore

摘要

The present work aims at identifying, locating and quantifying the industrial and domestic waste dump sites located in and around Bangalore urban and rural districts of Karnataka state, India. Bangalore has a population of 6 million and has more than 2000 industries working at various industrial estates and other locations around the city. It was reported that about 1500 tons of municipal waste per day is being generated from Bangalore city. Studies reveal that there is no scientific treatment and disposal facility for scientific management of the waste generated. The waste from industries and community areas is disposed in an unscientific manner at several open dump sites across the city. There are more than 60 dump sites consisting of both municipal and industrial waste existing in and around Bangalore city; the locations are totally unhygienic. Based on the experience gained from field visits, physical observation of the waste disposed, quantity and nature of the waste disposed, each site was given with a grading based on polluting potential of the site. For selected sites, ground water samples were collected from nearby surface or bore wells and analysed for possible contamination. From the study, it was found that the site needed immediate attention and comes under severe impact category of 27 numbers and that of medium and low impact are 18 and 6 numbers, respectively. The disposal sites have got tremendous potential of spreading the epidemics/diseases to the people living in their immediate vicinity and at nearby places.
