What Are the Risks at the Site?

The initial response (the installation of temporary soil cover in 2013) at the impacted residential properties on Water Street reduced the potential for exposure to hazardous substances while further studies could be performed. The subsequent permanent relocation of the residents at these properties eliminated the potential for exposure by the residents to contaminated soil. Fencing installed subsequent to the demolition of the structures on the impacted Water Street properties and the building at the former Flintkote Plant property, pursuant to the remedial decision in 2013, further reduced the potential for exposure to hazardous substances while the remedial designs for the remainder of the response actions for contaminated soil at OU1 and OU2 are underway.

The soils at the former Flintkote Plant property, the White Transportation property, the United Paperboard property, and Upson Park were found to present an unacceptable risk. The remedial decision in 2017 will address the unacceptable risks associated with soil and sediment contamination in the Creek Corridor. The soils at Upson Park that were found to present an unacceptable risk are located within the heavily forested and extremely steep banks of the Creek. This area is not easily accessible and therefore does not present an unacceptable risk to visitors based on the limited access under current conditions. However, the concentrations in these subsurface soils pose an unacceptable risk based specifically on future land use, which is the basis for EPA’s planned action to excavate these contaminated soils at the Site. NYSDOH has issued an “eat none” advisory for any fish caught in the Creek.

As part of the RI/FS for OU3, a human health and ecological risk assessment will be conducted.

The results of the Human Health Risk Assessment at OU4 indicate that lead in soil could present adverse hazards to current and future residents. EPA selected a remedy in Sepember 2018 to remove contaminated soil above cleanup levels, which will prevent risks resulting from direct contact with the lead-contaminated soil.

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.
