What Are the Risks at the Site?

A fence surrounds the property to deter trespassing. Odors of naphthalene vapors generated at the site from disturbance of contaminated soil have traveled off site to adjacent residential developments. While the odors can be offensive to some people, the presence of the odor does not necessarily mean that there is an effect on people’s health. 

Recreating in the water near the site and eating crabs caught near the site are not advised. Fish consumption advisories are in effect for fish and shellfish caught in this area.

Contaminant Information

The main contaminants being remediated are coal tar and arsenic. Groundwater underneath the site is contaminated with arsenic, chromium, lead, polycyclic aromatic hydrocarbons (PAHs), and volatile organic compounds (VOCs). Subsurface soils at the site are predominantly contaminated with arsenic, chromium, lead, and PAHs. Several plumes of non-aqueous phase liquid (NAPL) lie beneath the site. PCBs were detected at low levels in the soil in localized areas.  Surface water and river sediments are contaminated with PAHs and arsenic.

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 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.
