What Are the Risks at the Site?
At each site, EPA determines the possibility for human and ecological contact (i.e., exposure) with contaminants at the site. EPA determines if the site poses a risk to humans, and if so, identifies actions that can be taken to control any possible exposure to humans until site cleanup has been completed. Once complete, cleanup provides long-term human health and environmental protection at the site. (Superfund risk assessment process)The most recent Five Year Review was published by EPA HQs in 2018.
Site investigations identified contamination in soil and groundwater that could potentially harm people in the area. Soil and groundwater contamination resulted from waste handling practices at the site.
The site is unoccupied and fenced to restrict access. A land use restriction on the site property prohibits placement of groundwater wells. Residents do not use groundwater in the upper-level aquifer as a source of drinking water. All properties located downhill from the site connect to the public water system. Based on a well survey in 2008, the nearest residence that relies upon well water is located about one mile northeast of the site. No private wells are currently located in the area of groundwater contamination.
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||Yes||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||Yes||
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.
