What Are the Risks at the Site?

Moton School
No health or environmental problems detected; the school was built on top of 3 to 5 feet of clean fill.

Shallow Ground Water
Contaminated with elevated levels of metals.  However, this aquifer is not used by humans and does not impact surface water.

Residential Areas - Soils
Surface Contamination (prior to the implementation of the 1997 Action Memorandum) - Marginal human health risk:

  • 1.3 X 10-4 lifetime cancer risk (all contaminants of concern);
  • 6.1% children with projected risk (Lead (Pb) concentrations 500 to 1,000 parts per million (pm)). 

Future Surface Contamination - If landfill materials below the top foot of soils were exposed due to human activity, health risks would increase to:

  • 5.0 X 10-4 lifetime cancer risk (all contaminants of concern);
  • 63.8% children with projected risk (Pb concentrations 1,000 to 4,000 ppm).

Undeveloped Property Soils
Surface Contamination - Prior to the cleanup, contamination levels on the undeveloped property (OU1) ranged from 37.2 to 28,300 ppm lead.  The site was covered with dense vegetation and surrounded with an 8-foot fence. 
Future Surface Contamination - City zoned tracts "commercial."

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.

Performance
Measure
Status at this
Superfund Site
What does this mean?
Human Exposure Under Control Yes 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 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.

Construction Complete Yes

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:
  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.
