Is there PFAS in Edmond Pwa - Arcadia tap water?
Yes, and above the federal limit. The highest PFOA or PFOS reading was 6.4 parts per trillion, against a limit of 4.
Edmond Pwa - Arcadia is a public water system in Oklahoma, serving more than 10,000 people. The EPA required almost every system in the country to test for 29 PFAS compounds and published every result. These are that system’s own readings, not an estimate and not ours.
Every compound tested, 6 of 29 found

Every row is a compound the EPA required this system to test for, whether it was found or not. Readings are the highest single result the system reported. Compliance is judged on an annual average, so one high sample is not by itself a violation. “Not detected” means below the level the laboratory method can measure, which is not the same as zero. Last sample 1/7/2025.
What actually removes it
Boiling does not remove PFAS and concentrates it. Reverse osmosis and certified activated carbon do. These are the highest-graded filters in our database, scored 0 to 100 on the chemistry of the filter itself.
