What Are the Risks at the Site?
Risks addressed by the cleanup include health risks from people ingesting or touching contaminated groundwater, sediment and soil. EPA conducted cleanup activities in 2010, to remove contaminated soils from Hunt Intermediate School, Maranatha Faith Center and a nearby residential property on Moss Street. EPA also placed a fence around a potentially contaminated part of a drainage ditch to prevent access. EPA is currently conducting a remedial investigation/feasibility study to assess threats to people living near the site and to the environment, and evaluate cleanup options.
Most residents and businesses in the area use the public water system. Although the site-related groundwater investigation is ongiong, As part of its investigation, EPA has determined that the public water supply wells are not impacted by the site because drinking water wells are located at depths ranging from 885 to 915 feet below ground surface (bgs) and are isolated from the potentially contaminated shallow aquifer. As part of the RI, EPA plans to coordinate with local authorities to make sure no one is using a private well affected by shallow groundwater contamination.
The majority of chemicals of potential concern (COPCs) in the PineYard is associated with wood treating-related chemicals, primarily Polycyclic Aromatic Hydrocarbons (PAHs),Exit Pentachlorophenol (PCP), chromium,Exit and dioxinsExit (TEQdf)) are carcinogens and could pose unaccepatable risks to human health and the environment.
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
|What does this mean?|
|Human Exposure Under Control||Insufficient Data||Yes means assessments indicate that across the entire site:
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:
|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.
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:
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.
