A company known for mixing firefighting foam containing "forever chemicals" in northeastern Wisconsin is aiming to reduce the amount of contamination in the soil beneath its facility, but it won't be able to eliminate the hazardous compounds completely.
Tyco Fire Products, a subsidiary of Johnson Controls, will begin work on a groundwater extraction treatment system this year, according to conditional approval it received from the state Department of Natural Resources. The system is expected to be built and start cleaning water by the end of the year.
The system will remove water from the ground underneath the company's property via extraction wells, according to a DNR release, and will be fed into a treatment system building on the property. The treated water will then be released into what is known on the site as Ditch B, near Pierce Avenue in Marinette.
