Public Notice: EPA Begins Sixth Review of Adam’s Plating Superfund Site
Summary
The U.S. Environmental Protection Agency is conducting its sixth five-year review of the Adam’s Plating Superfund Site. The Superfund law requires regular checkups of sites that have been cleaned up - with waste managed on-site - to make sure the cleanup continues to protect people and the environment. A summary of the cleanup activities and an evaluation of the protectiveness of the implemented cleanup remedies will be included in the five-year review report.
Cleanup actions at the site included:
- Removing contaminated soil and installing vertical barriers against clean filled soil to reduce recontamination.
- Monitoring groundwater to see any potential movement of contaminated groundwater off-site.
- Restricting site use.
During the five-year review EPA will be conducting a site inspection, reviewing the status of the cleanup, and conducting a review of the current data.
Other planned cleanup actions for remaining contaminated vapors at the site include:
- Installing a vapor intrusion mitigation system in the basement of an affected residential property to passively carry the contaminated vapors from underneath the building to the outside.
- Updating deed restrictions to require a vapor mitigation system be installed if a building were to be constructed on the Adams Plating site property.
Previous Site Review
In June 2022, EPA found that the remedy was not protective of health because of risk of exposure to contaminated vapors at an unoccupied residential property. EPA is addressing this by installing a vapor intrusion mitigation system and is investigating potential sources of contamination in groundwater at the site. Updates on this work will be given in the June 2025 five-year review.
In June 2022, EPA found that more information is needed about groundwater migration at the site. EPA anticipates having sufficient information to determine if the contaminated groundwater migration is under control as part of the June 2025 five-year review.
