The report discusses numerical criteria for the reuse and disposal of municipal sewage sludge and evaluates reductions in human health risks or benefits derived from controlling sludge disposal practices. Quantitative aggregate risk estimates are projected for 31 contaminants for each of the key sludge management practices: incineration; monofilling; land application (food chain and non-food chain); and distribution and marketing. The study utilizes state-of-the-art fate, transport and exposure methodologies in predicting environmental concentrations. The analysis evaluates a number of human exposure routes including dietary, drinking water and inhalation pathways. The analysis couples this information with national and local populations exposed along with the Agency's most recent health effects data in assessing risks. A methodology for quantitatively assessing non-carcinogenic effects from exposure to lead is introduced.
