<P> Leachate from a landfill varies widely in composition depending on the age of the landfill and the type of waste that it contains . It usually contains both dissolved and suspended material . The generation of leachate is caused principally by precipitation percolating through waste deposited in a landfill . Once in contact with decomposing solid waste , the percolating water becomes contaminated , and if it then flows out of the waste material it is termed leachate . Additional leachate volume is produced during this decomposition of carbonaceous material producing a wide range of other materials including methane , carbon dioxide and a complex mixture of organic acids , aldehydes , alcohols and simple sugars . </P>
