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 2015.
Currently, there is no risk to human health, because presently the groundwater is not being used for drinking water. A recent receptor survey of nearby wells indicates that there are numerous private water wells within a one half-mile radius of the Site, however, there are currently no impacted private water wells. Groundwater at the site is a potential future source of drinking water as designated by the North Carolina Groundwater Classification. ICs are necessary for the soils and to prohibit the installation of potable water wells until the groundwater is restored to drinking water standards.
In 2013, EPA reviewed the Potentially Responsible Party’s (PRP) evaluation of vapor intrusion at the Oak Ridge Apartments. Specifically, the review noted the presence of increased concentrations of chlorinated volatile organic compounds in the vicinity of the downgradient Oak Ridge property (monitoring well CMMW23) and requested a second vapor intrusion study. The results of the April 2013 indoor air, outdoor air, and sub-slab vapot sampling in additiona to the June groundwater sampling results indicate that ther is not a complete groundwater to indoor air vapor intrusion pathway at Oak Ridge that could create a potential risk/hazard above EPA's target levels.
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.
