Community PFAS Testing
Massachusetts Water Resources Authority
WAKEFIELD
You might have seen recent news reports about per-and polyfluoroalkyl substances (together abbreviated as PFAS). These are a class of human-made chemicals typically associated with certain fire-fighting foams. These chemicals are persistent and have been used in products we all use for decades.
The results are below the regulatory levels being considered by MassDEP for drinking water.
2022 PFAS Test Results for Wakefield
Q4 2022 Results:
| PFAS Analyte (results in ppt) | Average Level | Range | Highest Level Allowed |
