Lead contamination at Superfund sites presents a threat to human health and the environment. This Web site describes EPA’s approach to addressing those risks, and the challenges of remediating lead contamination at Superfund sites.
This site also provides information to risk assessors at Superfund sites about how to use the Integrated Exposure Uptake Biokinetic (IEUBK) model and the Adult Lead Methodology (ALM) to estimate the concentration of lead in the blood of children, pregnant women, and their developing fetuses who might be exposed to lead-contaminated soils. The level to which EPA remediates lead contamination at Superfund sites is in large part determined by risk assessors' application of the IEUBK model and the ALM to estimate blood lead concentrations, which can then be correlated to estimate possible adverse health effects in persons who have been exposed.
