ABSTRACT Despite the charges by Stifelman et al., nowhere do we claim that blood lead levels (BLLs) were used as the sole criterion for cleanup actions at Bunker Hill. Rather, we argue that insofar as BLLs were one of the Remedial Action Objectives (RAOs) specified in the Record of Decision (ROD), this criterion was neither protective nor proactive in reducing risk. The threshold of concern (10 μg/dL) is far too high in light of a mounting body of evidence showing the adverse effect of lead at much lower levels.(1-6) In addition, the other RAOs for environmental criteria (e.g., soil, dust, and water contaminant levels) were set at levels much higher than the Environmental Protection Agency's (EPA's) own standards.(7) (Am J Public Health.
