Abstract: Disposal of municipal sludges in dedicated sanitary landfills can be environmentally acceptable. Contaminants within the sludge present the potential for public health risks but these risks can be minimized through proper design, construction and operation of the landfill. The design of such a landfill must address each possible pathway that a pollutant would follow in exiting the landfill and contacting human receptors. These pathways include underground leaching, surface runoff and airborne pollution. This paper will focus upon underground leaching of heavy metals since it is considered the most significant pathway of metal contaminant migration. (Author abstract. )
