Groundwater Testing in Marinette and Peshtigo

Marinette, Wisconsin Fire Technology Center:
Latest Updates on the Investigation

July 17, 2018 Update

As part of the work plan that we submitted to the Wisconsin Department of Natural Resources (DNR) in March 2018, we have been conducting additional investigations of groundwater, soil, ditches and surface water in and around the Fire Technology Center (FTC) in Marinette and the Town of Peshtigo. In following that plan, we collected surface water samples in two ditches that run through and near the FTC and lead to Green Bay.

The laboratory results for those samples from the ditches have been received, and PFAS has been detected in the samples.

Due to the locations of the ditches and the proximity to Green Bay, we’re focusing our efforts to determine the pathways of these compounds entering the ditches and to identify potential interim measures to address PFAS in the ditches. We are working closely with DNR to obtain approval for work plans and the necessary permits to remove the compounds from the water that are flowing through the ditches. We view this as a current priority.

We have no information that indicates water in the ditches is used for drinking water purposes.

Notwithstanding, we take these results seriously. We are moving immediately to consult with DNR on the interim action steps that we can take. We are also moving quickly to collect samples from some other ditches in the City of Marinette and Town of Peshtigo that have not been sampled to date. We will continue to be transparent and keep the community, as well all interested parties, informed of our progress in finalizing these interim action steps.

Tyco has been looking into some concerns we’ve heard from a few of the residents in the area: specifically, some have spoken to us about inconveniences of using bottled water for extended periods of time. We are therefore reaching out to residents or business owners whose drinking water wells had detections of PFAS, but the levels were below the Health Advisory Level (HAL) established by the US Environmental Protection Agency (EPA) for PFOA and/or PFOS. We have decided to offer each of these homes or businesses the option to switch off of bottled water and install a “Point of Entry Treatment” (POET) water system. POET systems can effectively treat PFOA and/or PFOS in drinking water. Tyco is committed to pay for the installation, maintenance and regular monitoring of these systems.

We do want to reiterate that the sampling results indicated a detection of PFOA and/or PFOS that is below the HAL that has been set by the EPA. Nevertheless, as an accommodation to our neighbors and to provide a level of convenience, Tyco is offering these properties the choice to replace their bottled water service with the installation of a POET.
