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.
- Risks and pathways addressed by the cleanup include health risks from people ingesting or touching contaminants in debris, groundwater, soil, sediment and surface water. Contamination resulted from pesticide formulation and related waste disposal practices at the site.
- Contamination affected groundwater used for both the public water system and private water wells. EPA has contacted property owners with property overlying impacted groundwater. A public water supply well is located downhill from the R211 Area; it is the only known well affected by site contamination.
- The PRPs installed and maintain a groundwater treatment system (activated carbon absorption) at the well used by the local water utility to provide water to area residents. At all other areas, groundwater discharges to surface water. Sampling indicates there is no risk to people from coming into contact with contaminants in surface water.
- EPA assessed whether residents or workers might be at risk from harmful groundwater vapors in buildings. EPA found that vapor intrusion did not pose a threat to residents and workers. The use of fencing and warning signs addressed all other threats at the site.
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||Yes||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.
