Though PFAS are now ubiquitous, no nationwide surface water quality survey has ever been taken.
As a result, the extent of PFAS contamination is unknown for most U.S. waters.
To address this troubling lack of information about the presence of, and dangers posed by, PFAS in U.S. surface waters, Waterkeeper Alliance worked with 113 Waterkeeper groups across the United States on an unprecedented initiative to test U.S. surface waters for PFAS contamination.
The results unequivocally show that dangerous PFAS pollution is widespread in surface waters across the country.
83% of the samples showed detection of at least one PFAS compound. In some cases, contamination reached into the thousands of parts per trillion.
