Conversion of urban solid waste to energy often produces solid residues that require subsequent disposal. Generally they are placed in ash ponds, spread on land, or placed in sanitary landfills. These residues were studied, and the potential environmental problems associated with their disposal were assessed. Peak concentrations of various leachate constituents exceed permissible discharge standards. These materials leach rapidly from the residues so that the total leached mass per unit of residue is quite small. Therefore, some type of treatment of ash pond overflow may be required if controlled discharge will not keep constitutent concentrations below permissible discharge levels.
