What Are the Risks at the Site?

There is insufficient information to determine the Human Exposure Control status for OU1 and OU3. The site is located on an approximately 80-acre property containing an active scrap metal recycling facility, a junkyard, and an inactive landfill. Woodbury Creek borders it to the west, Hessian Run to the north, and a residential community to the south. Sources of contamination on the site include an approximately five-acre pile of lead-containing crushed battery casings, an approximately six-acre inactive landfill in the north-central portion of the site, and lead- and PCB-contaminated soil located throughout the property. The company deposited crushed battery casings directly into Hessian Run and the wetlands adjacent to it, altering the shoreline. Matteo (under NJDEP oversight), NJDEP and EPA all have conducted investigations at OU1. EPA sampling in 2005 and 2006 revealed crushed battery casings and lead contamination adjacent to and in the residential community. Under a May 2006 Administrative Consent Order issued by EPA, Matteo installed a chain-link fence to restrict access to contaminated areas. To facilitate the fence installation, approximately 425 tons of contaminated soil were excavated for off-site disposal.

Contamination associated with the disposal of crushed battery casing waste has been identified at various locations throughout OU2. The current land use at OU2 is residential, which is not expected to change. A baseline human health risk assessment (HHRA) was completed in March 2017 that characterized residential exposure to soils within OU2. Results of the HHRA indicated there is unacceptable risk from exposure to soils for the current and future residential child and adult, primarily due to incidental ingestion. Lead is considered the principal site-related contaminant, although antimony and PCBs (Aroclor 1254) contributed to elevated estimates of risk as well.

EPA has already initiated cleanup activities at OU2 including the removal of contaminated soil at three residential properties and placement of temporary barriers to prevent exposure to surface soils by residents on certain properties with elevated concentrations of lead.

Additionally, EPA ensures community participation throughout the remedial process by meeting with residents and affected stakeholders, issuing public notices and updating fact sheets. A site profile has been established on the EPA website to keep the community informed of recent progress at the site. Additionally, an EPA Community Involvement Coordinator is assigned to the site and can address specific community concerns as they arise.

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 No 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.
