Groundwater Test Results Continue to Provide Further Guidance on Location of Permanent PFAS Source-Control Solution

The results of new groundwater tests reported to property owners and the WDNR today are consistent with previous results and the groundwater model we are using to design and install a permanent source-control system.

The groundwater samples were taken in November in the same locations as the surface water samples upstream and downstream from the existing Ditch B treatment system but from beneath the bottom of the ditch. As expected, the groundwater samples show elevated levels of PFAS.

Combined with the surface water results, this additional data provides further guidance to precisely identify where the PFAS contamination from the Tyco Fire Technology Center is entering Ditch B so we know exactly where to locate the permanent source-control solution to stop PFAS infiltration into Ditch B.
