Landfill leachate quality evaluation through the landfill pollution index

Recent regulations in the field of solid waste management require treatments before the disposal of municipal waste on landfills. Chemical and physical parameters of the landfill leachate can be used for evaluation of the landfill age as the main parameter for the stage of degradation inside the landfill body. In order to estimate the impact of leachate pollution into the environment, different pollution indexes can be calculated. One of common indexes is the Leachate Pollution Index (LPI) suggested by Kumar and Alappat, who have developed a system of comparing leachate pollution potentials of various landfill sites, in relation with the content of a particular pollutant. This calculation includes the concentration and significance of each pollutant and can be used as the main criterion for ranking of the environmental impact and for the design of leachate treatment processes. LPI has been calculated for the “Bikarac” landfill based on the following parameters: suspended matter, COD, BOD, ammonia nitrogen, zinc, copper, nickel, mercury, arsenic phenolic compounds, chlorides and pH value. The calculated results are discussed and compared with the literature data.
