Is 10 µg/dL (in the construction scenario) a level that should never be exceeded?
No. The 10 µg/dL is a multi-Agency goal that has been designated by the U.S. Centers for Disease Control (CDC) and the Agency for Toxic Substances and Disease Registry (ATSDR) as a level of concern to protect sensitive populations (neonates, infants, and children). The protection of sensitive populations is assumed to also provide protection for adults. EPA s stated goal for lead is that children (up to 84 months of age) exposed at a risk-based cleanup level would have no more than a five per cent probability of exceeding the level of concern (U.S. EPA, 1994; U.S. EPA, 1998). The adult lead methodology extends that same concept to develop cleanup goals preventive of fetal risk. As a statistical goal, a probability of exceedance of up to five per cent of the goal is acceptable.
