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)Site investigations found contamination in groundwater, surface water, soil, sediment and aquatic biota that could potentially harm people in the area or the environment. Contamination resulted from manufacturing operations and waste handling practices at the site.
- EPA and NCDENR found large areas on barren soil and stressed wetlands downgradient from the former manufacturing plants due to low pH of the soil. Surface water drains to Livingston Creek and the Cape Fear River about two miles from the site. Contamination affected sediment in Livingston Creek as well as clam and fish tissue and the wetlands area of the creek.
- Soil contamination, sediment and surface water contamination in Livingston Creek, and the potential discharge of contaminated groundwater to surface water pose a potential threat to anglers and trespassers on site.
- Sampling indicated contamination in groundwater on site. However, EPA does not believe the groundwater flows in the direction of private wells.
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.
