69 Environment “This tool can be very helpful for legislators to understand if PFAS contamination has been detected in their districts and how it impacts their constituents,” Johnson said. “As more communities witness the impact of PFAS, it will become more of a unifying issue.” Continued sampling will improve understanding the need to reduce PFAS contamination levels and break the cycle of forever contamination. In the US, the Great Lakes states have been quick to act on PFAS, given their role as stewards of 95 percent of the fresh surface water in North America. More states are taking on this problem, starting with testing and putting test results on a map. As PFAS contamination becomes more understood and strategies emerge, maps will be central to the worldwide cleanup effort. Airports often land on the PFAS contamination list, as do fire training sites. The Wisconsin PFAS Interactive Data Viewer maps cleanup sites, water samples, and fish consumption advice.
