Drinking water samples collected from the Menominee and Marinette Municipal water supplies last Monday and Tuesday showed higher levels of some types of PFAS in the water than seen in past sampling by the cities, indicating an impact of runoff from the Industrial fire at Resolute Forest Products and the adjacent warehouse.

Four PFAS compounds were found in the Menominee treated drinking water and three in  Marinette treated drinking water.  Four years of monitoring data of the Menominee Public Water Supply had never found detections of three of the compounds. In Marinette, water levels of one compound have shown an increase while two others have been detected for the first time.

Treated drinking water results received as of Sunday for the cities of Menominee and Marinette show PFAS levels still below Michigan or Wisconsin health-based or regulatory standards for measured PFAS compounds and authorities determined that public risks from these PFAS are considered low. If future sampling shows results above state health-based or regulatory standards, further action will be taken, and residents will be notified immediately.

Meanwhile,  Fire suppression operations continue to identify and extinguish remaining smoldering hot spots in burned out areas of the warehouse. These actions are being led by an MDNR wildland fire Incident Management Team. Demolition and debris removal are well underway.  Warehouse owner KKIL and Resolute Forest Products are coordinating these efforts. The EPA will continue to perform community air sampling and monitoring until the Unified Command determines that it can be scaled down over the coming days because of steadily improving fire suppression and debris management on-site.   Several million gallons of fire suppression water were collected to prevent runoff of fire related contaminants to the Menominee River. Construction of a water treatment system to treat this water has begun. Tyco Fire and its contractors Arcadis and Clean Harbors lead this effort, which is being coordinated and overseen by EGLE and the EPA.
