This is one of a series of reports that present methodologies for assessing the potential risks to humans or other organisms from the disposal or reuse of municipal sludge. he sludge management practices addressed by this series include distribution and marketing programs, landfilling, surface disposal, incineration and ocean disposal. n particular, these reports provide methods for evaluating potential health and environmental risks from toxic chemicals that may be present in sludge. his document addresses risks from chemicals associated with surface disposal of municipal sludge. he proposed risk assessment procedures are designed as tools to assist in the development of regulations for sludge management practices. he procedures are structured to allow calculation of technical criteria for sludge disposal/reuse options based on the potential for adverse health or environmental impacts. he criteria may address management practices (such as site design or process control specifications), limits on sludge disposal rates or limits on toxic chemical concentrations in the sludge.
