metals such as mercury, phenols and derivatives and other chemicals used in hospital laboratories were found to have been discharged into the general sewerage systems. There is evidence that these chemicals interrupt the natural ecosystems and cause toxic effects in plants (Blenkharn, 2006). Hazardous waste was found to have been dumped in city corporation bins, and finally disposed of on general landfill sites, which may contaminate ground water, especially low-lying areas subject to frequent flooding. In the present study, it was observed that, during the rainy season, leachate from dumps used for medical waste infiltrated into water that was being used for washing and household purposes as well as for agriculture.
