The District has completed the first phase of its PFAS sampling and analysis plan, and the results are favorable.
The first phase of the plan tested for 33 PFAS compounds, as outlined by the Wisconsin Department of Natural Resources (WDNR). The District’s influent (incoming wastewater), effluent (outgoing, cleaned wastewater) and biosolids were tested. Struvite, a phosphorus-rich nutrient recovered from wastewater, and polymers, which are used in the treatment of biosolids, were also tested.
Samples were collected by a consultant, TRC, using lab-accepted collection methodologies. The samples were analyzed by Eurofins|TestAmerica, which is certified by WNDR to conduct PFAS testing.
Overall, the results of the District’s initial testing were as expected based on the characteristics of the 180-square-mile service area.
Sampling highlights are summarized below.
