About PFAS contamination in Stuart
## Summary Stuart's municipal water system earned a B grade for PFAS contamination, indicating detectable levels of these chemicals but no confirmed exceedances of federal limits based on available data. None of the compounds with established EPA limits — PFOA and PFOS, each capped at 4 parts per trillion — had concentrations reported in this testing cycle. One compound, PFHxA, was detected at 7.9 parts per trillion, though no federal limit currently exists for that specific chemical. The source of contamination has been identified as firefighter training activities involving AFFF, a foam historically used at fire stations and airports.
## What the data shows Of the 15 PFAS compounds tested at Stuart's Water Plant, only one — PFHxA — returned a measurable concentration of 7.9 parts per trillion. The remaining 14 compounds, including the two with established EPA limits (PFOA and PFOS), had no concentration reported, meaning they were either undetected or below reporting thresholds. Because PFHxA has no federal maximum contaminant level, its detection does not constitute a regulatory violation, though it does confirm the presence of PFAS in the system.
## What residents should know Stuart is currently a lead plaintiff in litigation against 3M over PFAS contamination, with Phase 2 legal deadlines set for June and July 2026 — meaning potential settlement funds could support future remediation efforts. Residents with specific concerns about their tap water can contact the City of Stuart's utility department for the most current testing results and any updates to treatment measures. Monitoring this situation as federal regulations on additional PFAS compounds continue to evolve is advisable.
About this summary: Narrative text on this page was drafted by an AI model (claude-sonnet-4-6) from EPA UCMR 5 data and reviewed before publication. The numeric data above is reported by water utilities directly to the EPA. If you spot an error, email data@checkyourwater.org.
What Stuart residents can do
PFAS were detected in Stuart's water but levels are well below federal limits. Steps to maintain awareness:
- Read your utility's annual Consumer Confidence Report (CCR) — request a copy if you don't receive one.
- Sign up for water quality alerts from your utility.
- If you're on a private well, get it independently tested for PFAS.
- Reduce PFAS exposure from non-water sources: avoid non-stick cookware, stain-resistant fabrics, and grease-resistant food packaging.
Primary contamination source: Firefighter training / AFFF
Settlement information: Lead 3M plaintiff city; Phase 2 deadlines June/July 2026
