What is the potential danger posed by historical lead smelting sites?
The potential danger posed by historical lead smelting sites varies by site and depends upon whether a completed exposure pathway to the contaminant exists. For example, if site surfaces are redeveloped and, as a result, covered, there is no direct contact. Therefore, without such exposure, there is no current human health risk. If direct contact is occurring, the potential depends upon a number of factors such as the frequency of exposure and who is exposed, e.g., child, pregnant woman, etc. For more information on lead at super fund sites visit https://www.epa.gov/superfund/lead-superfund-sites.
