What Are the Risks at the Site?

 

Groundwater beneath the Site contains various Volatile Organic Compounds (VOCs), primarily trichloroethene (TCE). However, the soil contaminated with VOCs at the Site has been removed, and institutional controls are in place to ensure that no one can ingest or come in direct contact with contaminated groundwater. A vapor intrusion investigation completed in the building previously located at the site in 2013 showed no evidence of unacceptable vapor intrusion. This building was later demolished and the Site is being redeveloped. The State is working with the developer to ensure preemptive mitigation systems are installed beneath the new buildings to prevent potential trichloroethene (TCE) vapor intrusion. Similar investigations in nearby residences and school buildings have shown evidence of VI in over 55 residences and ten school buildings, and mitigation systems are being installed in the affected buildings to prevent TCE vapors from accumulating indoors at unacceptable levels.

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.
