Detected — below EPA limits
Plain English
01What 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. Continue reading your utility's annual Consumer Confidence Report for year-to-year trends.
What to do next
02Three concrete steps
- 01
Install a certified filter
A reverse osmosis or NSF/ANSI 58-certified carbon block at your kitchen tap is the most reliable solution. Standard pitcher filters (Brita, PUR) don't remove PFAS unless explicitly certified for it. See certified filter picks →
- 02
Read your utility's CCR
Your water utility publishes an annual Consumer Confidence Report covering the previous year's water quality, including their PFAS treatment plan if any. More detailed than this site's summary. How to read a CCR →
- 03
Reduce other exposure routes
Water isn't the only input. Replace badly-scratched non-stick pans, skip microwave popcorn bags and greaseproof fast-food wrappers, and choose stainless or cast iron cookware. Full action plan on the FAQ →

Source & Methodology
About this data
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. "Not detected" means below the MRL, not literally zero.
