What Are the Risks at the Site?
Exposure to metals in surface soils, subsurface soils, and sediments found at various exposure areas of the Burn Site were associated with cancer risk and noncancer hazard that exceed EPA’s threshold criteria. In general, arsenic and/or lead were the main contaminants of concern; however, exposure to other chemicals were also identified as exceeding cancer risk or noncancer hazard estimates at some of the exposure areas evaluated (e.g. hexavalent chromium at the Burn Site Fenced Area).
The results of the RI showed that lead and arsenic are the major contaminants of concern throughout the Burn Site. Other contaminants that were found in the soil above the standard include pentachlorophenol, hexavalent chromium and other metals, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs). These other contaminants were found less frequently and are co-located with lead and arsenic, therefore they will be addressed with the cleanup goals for lead and arsenic.
EPA uses performance measures to track environmental results at Superfund sites. If you have any questions or concerns about the measures at this site, please contact the site team members listed under Site Contacts.

|Status at this
|What does this mean?|
|Human Exposure Under Control||Insufficient Data||Yes means assessments indicate that across the entire site:
No means an unsafe level of contamination has been detected at the site and a reasonable expectation exists that people could be exposed.Insufficient data means that, due to uncertainty regarding exposures, one cannot draw conclusions as to whether human exposures are controlled, typically because:
|Groundwater Migration Under Control||Insufficient Data||
Yes means EPA reviewed all information on known and reasonably expected groundwater contamination. EPA concluded the migration of contaminated groundwater is stabilized and there is no unacceptable discharge to surface water. EPA will conduct monitoring to confirm that affected groundwater remains in the original area of contamination.
No means EPA has reviewed all information on known and reasonably expected groundwater contamination, and the migration of contaminated groundwater is not stabilized.
Insufficient data means that due to uncertainty regarding contaminated groundwater migration, EPA cannot draw conclusions as to whether the migration of contaminated groundwater is stabilized.
Yes means the physical construction of the cleanup is complete for the entire site.
No means either physical construction is not complete or actions are still needed to address contamination.
|Sitewide Ready for Anticipated Use||No||Yes means:
No means that one or more of these three criteria have not been met. However, a site listed as no may still have redevelopment occurring on portions of the site and may be eligible for additional redevelopment.
