Landfill typical leachate values

Leachates generated from municipal landfills are complex effluents that contain high concentrations of organic pollutants, ammonium, chloride, and many other soluble compounds. Table 1 lists the typical concentrations found in the leachate of a mature landfill site [1, 2], With regard to the value of BOD5/COD, this leachate may be classified as a poorly biodegradable wastewater.
