Abstract

Aim: Rapid population growth, urban sprawl and industrial development has led to increased disposal of Municipal Solid Waste. Proper segregation and disposal is required for effective management of waste. The solid waste dump site causes a major impact to the environment and to the living beings if not properly managed. Hence, this study was carried out to assess municipal solid waste dump site at Vellalore, Coimbatore.    

Methodology: Soil and leachate samples were collected from the dump site and analyzed for various chemical and biological parameters. The groundwater samples were collected from nearby localities and analyzed. The Leachate Pollution Index (LPI) was calculated by Delphi technique and compared with standard LPI.    

Results: The results indicate that the soil and groundwater samples are highly polluted and the LPI index from the leachate collection tanks 1 and 2 of the sanitary landfill located in the integrated solid waste management plant, Vellalore, Coimbatore were much higher than the LPI standard value.    

Interpretation: Proper treatment of leachate is required before it is discharged into the environment. Soil and ground water pollution is to be minimized by scientific treatment of waste.

Key words: Environmental Assessment, Ground Water, Leachate Pollution Index, Solid waste
