What Are the Risks at the Site?
There is insufficient information to determine the site-wide Human Exposure Control status at the Shieldalloy Metallurgical Superfund site. A remedy has been selected for OU1 (non-perchlorate contamination in groundwater) and OU2 (non-perchlorate contamination in soils, sediments, and surface water). The selected remedy for OU1 calls for changing the existing pump-and-treat remedy to in-situ remediation, monitored natural attenuation, institutional controls, long-term monitoring and five-year reviews. The selected remedy for OU2 calls for capping facility soils, excavating sediments from the Hudson Branch, and institutional controls. Currently, the OU3 RI/FS is being conducted to determine the nature and extent of perchlorate contamination in soils, sediments, groundwater, and surface water at the site and what risks exposure to these media might pose. The potential exposure pathways for OU3 are not yet identified; therefore there is insufficient data to determine the status of the site. 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.
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||No||
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.
