What Are the Risks at the Site?

A number of human health and ecological risk assessments have been conducted since the site was listed on the NPL. The human health risk assessments generally concluded that impoundments, soils and groundwater presented unacceptable cancer and noncancer human health risks to both current and potential future receptors. The ecological risk assessments concluded that the exposure of ecological receptors to sediment and surface water in the Raritan River and Cuckel’s Brook is unlikely to adversely affect the health and diversity of aquatic biota. It was also concluded that the risks associated with the exposure of ecological receptors to soils in the South and West areas is likely to be below levels of concern. An ecological risk assessment is currently in the process of being conducted for impoundments 13, 17 and 24 as part of the site-wide remedy implementation to determine whether their contents require relocation to the North Area in accordance with the implementation of the site-wide remedy. The remedies selected for the sites will address unacceptable risks associated with site soils, groundwater and impoundment contents.

CRISIS, a community-based group located in Bridgewater, NJ, was awarded a technical assistance grant from EPA. Technical assistance grants are awarded by EPA to help communities participate in Superfund cleanup decision-making. It provides funding to community groups to contract their own technical advisor to interpret and explain technical reports, site condi¬tions, and the status of EPA’s cleanup activities. For more information, please visit CRISIS’s website at:

An EPA Community Involvement Coordinator is also assigned to the site and is available to address specific community concerns as they arise.  The EPA Community Involvement Coordinator for the American Cyanamid Superfund Site is Melissa Dimas, who can be reached at 212-637-3677 or should you have any questions or concerns or wish to sign up to receive routine updates from EPA regarding the status of site

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 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.
