What Are the Risks at the Site?

  • In 2009, EPA found trichloroethylene (TCE) contamination in groundwater beneath the site at levels up to 20,000 micrograms per liter (μg/L). The U.S. Army Corps of Engineers (USACE) found even higher levels in the 1990s. The federal drinking water standard for TCE is 5 μg/L. Further work will be done during the Remedial Investigation to define the current state of the TCE-impacted groundwater beneath the site. Groundwater beneath the site is not used for drinking water.
  • In 2009, EPA also found polychlorinated biphenyls (PCBs) in site soils at levels that do not pose a public health threat, considering current land use at the site is commercial.
  • Fish were sampled in Rocky Creek by the USACE in 1996 and 1998. These fish were found to have unacceptable levels of PCBs.  Based on those samples, EPA continues to advise the public that fish should not be eaten from Rocky Creek downstream, and east, of Houston Road.

Performance Measures

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
Superfund Site
What does this mean?
Human Exposure Under Control Insufficient Data Yes means assessments indicate that across the entire site:
  1. There are currently no unacceptable human exposure pathways; and
  2. EPA has determined the site is under control for human exposure.

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:
  1. Response to the contamination has not begun; or
  2. The response has begun, but it has not yet generated information sufficiently reliable to evaluate whether there are currently any unacceptable human exposure pathways at the site.
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.

Construction Complete No

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:
  1. All cleanup goals affecting current and reasonably anticipated future land uses of the entire site have been achieved, so there are no unacceptable risks;
  2. All required land-use restrictions or other controls have been put in place; and
  3. The site has achieved Construction Complete status.

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.
