Description:
A methodology and accompanying model, SLDGFILL (sludge monofill), have been developed to assess the risk to human health posed by parasites, bacteria and viruses in municipal sewage sludge disposed of in sludge-only landfills (monofills). he following information is required for risk assessment of pathogens in sludges: (1) nature and amount of sludge; (2) physical attributes of the monofill site; (3) properties of the pathogens in sludge, including their concentration and survival capabilities (i.e., inactivation rates); (4) minimum infective dose to the receptor; and (5) fate and transport of the pathogens in soil and groundwater. he SLDGFILL model assumes an exposure pathway of infiltration from the monofill to groundwater and subsequent ingestion from a well by a human receptor. LDGFILL determines the probability of infection of the human receptor by pathogens in wellwater.
