PFC Contamination
  • Not Detected
  • Detected
  • Not Tested
Lower 48 Alaska Hawaii


The test results for perfluoroalkyl substances (PFAS), often referred to as PFCs, shown here are preliminary data collected by the EPA under the Unregulated Contaminant Monitoring Rule 3. The EPA has required testing for PFCs since 2013 and testing will continue until the end of 2015. Recent studies indicate that the safe level of PFOA or PFOS in water is significantly below the minimum reporting level required in the EPA testing.

PFOS = perfluorooctanesulfonic acid
PFOA = perfluorooctanoic acid
PFNA = perfluorononanoic acid
PFHxS = perfluorohexanesulfonic acid
PFHpA =perfluoroheptanoic acid
PFBS = perfluorobutanesulfonic acid
