ModerateWhat this means for you
PFAS were detected at this water system, but below the EPA's Maximum Contaminant Level. "Below the limit" doesn't mean no risk — it means EPA considers the concentration acceptable across a lifetime of consumption at that level. Some people, particularly pregnant women, infants, and those with compromised immune systems, may wish to take additional precaution. Using a filter certified NSF/ANSI 58 for PFOA/PFOS reduction is a reasonable step that costs little and eliminates this variable entirely.

Values shown are the highest single-sample concentration measured at entry points to the distribution system. Results reflect water quality at the treatment plant — aging pipes, building plumbing, and on-site storage can affect what actually reaches your tap.
