What Are the Risks at the Site?
The groundwater is contaminated with trichloroethylene (TCE) and its degradation products. The investigations have not found levels of the contaminants in domestic supply wells or local surface water bodies that would pose a risk to human health and the environment. A groundwater management zone instituted by Delaware Department of Natural Resources and Environmental Control (DNREC) helps to ensure that there is no direct contact with contaminated groundwater.
An evaluation for the potential of site-related contaminant vapors migrating from the groundwater plume and into the M&T Bank building was conducted in March 2015. The concentrations found below the building do not pose a risk to human health.
Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the Centers for Disease Control.
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||Yes||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||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.
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||Yes||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.
