Groundwater Cleanup to Begin This Summer Electro-Plating Services -1696 Site Madison Heights, Michigan July 2020 U.S. Environmental Protection Agency (EPA) and Michigan Department of Environment, Great Lakes, and Energy (EGLE) are implementing a plan to clean up groundwater contamination at the former Electro-Plating Services facility in Madison Heights. EGLE requested EPA assistance at the site in December 2019 when yellow-green liquid containing toxic chemicals from Electro-Plating Services seeped from tire former business onto the shoulder of 1-696. Contaminants at the site include hexavalent chromium, trichloroethylene, or TCE. cyanide, and per- and polyfluoroalkyl substances, known as PFAS. Since December 2019, EPA has collected over 270,000 gallons of contaminated groundwater and transported it off-site for treatment and disposal. While effective, this method is not sustainable long-term, as it is both costly and resource intensive. After evaluating several options, EPA and EGLE selected in-place treatment with a pemieable reactive barrier as the remedy for groundwater contamination. A penneable reactive barrier is created when chemicals are added to the ground in the path of groundwater flow to form a treatment zone. (See graphic below). Contaminated groundwater then flows through the zone where it is treated by the chemicals and comes out treated on the other side. A variety of treatment chemicals that break down and adsorb the different contaminants will be placed into the saturated soil between the EPS building and the service drive, as well as along the top of the 1-696 embankment. The treatment chemicals are non-toxic and not harmful. These treatment chemicals have been widely used on other sites, both at the state and federal level cleanup sites. To learn more about this treatment technology, see "A Citizens Guide to Pemieable Reactive Barriers" document, which can be found on the site's webpage listed in the box on the left. The cleanup transitions the site from the immediate response efforts that have been ongoing since December 2019 to a long-term management process that protects residents and natural resources. Cross-Section of Permeable Reactive Barrier Aboveground Contamination v m Water Table Groundwater Flow- Treated Water Permeable Reactive Barrier ------- Installation of the treatment chemicals will begin next month. EPA will conduct sampling to ensure the treatment is effective before stopping the current groundwater collection system. EPA expects to transfer the site to EGLE in December 2020 to maintain this new groundwater treatment remedy. It is estimated that the treatment materials may need to be reapplied every three to five years. The goal of the treatment is to clean the groundwater contamination as it moves off the Electro-Plating site and across the service drive. On-site soils still contain contaminants above clean-up criteria. Removing the source of the contamination (the building and site soil) will reduce the duration of groundwater treatment. Legal proceedings are currently underway to authorize demolition and removal of the Electro-Plating building. Additional investigation is required. It is anticipated that once the building has been removed source contamination can be addressed. Vacuum truck with high pressure pump cleaning out the storm sewer line along the service drive.
