EPA UCMR 5 results for 30 public water systems. 9 had at least one PFAS detected; 4 had a highest single PFOA or PFOS result above 4.0 ppt.
UCMR 5 is a one-time EPA monitoring program, not a compliance determination. The values shown are the highest single sample result at any of the system's sampling points; one result above 4.0 ppt does not mean the system violates the PFAS rule, which is judged on running annual averages under separate compliance monitoring. Results describe the public water system, not an individual home.
