What PFAS are
Per- and polyfluoroalkyl substances (PFAS) are a large family of synthetic chemicals that resist heat, water and grease. They have been used in coatings, fabrics, packaging and firefighting foams. Because they break down very slowly, they can be found in the environment, including groundwater. NMB Water's 2025 report notes that EPA finalized limits of 4 parts per trillion for PFOA and PFOS in 2024, with compliance due by 2031.
Where to see your utility's results
- NMB Water customers: the 2025 Water Quality Report has a separate "Additional Contaminants Monitoring" table listing PFOS, PFOA, PFNA, PFHxS and a PFAS hazard index, part of initial compliance monitoring now underway. It also says NMB voluntarily monitored 29 PFAS, and that its 2025 Unregulated Contaminant Monitoring Rule (UCMR) samples for lithium and PFAS analytes were all below minimum reporting levels.
- Miami-Dade WASD customers: WASD's Water Quality Report includes a PFAS table as part of monitoring for the new regulations.
Read the table for your utility rather than relying on summaries. The numbers, units and footnotes matter, and the reports explain what each column means.
What NMB Water says about its treatment
NMB Water's report states that the Norwood plant's reverse osmosis and nanofiltration processes reduce PFAS, and that it plans to retire its lime softening process by the EPA deadline as part of its improvement plans. WASD's report says it took proactive measures and will continue monitoring to stay in compliance. For questions about specific numbers, the utilities' water quality lines are the right place to ask: NMB's Water Quality Manager is at 305-948-2960.
Choosing a home filter for PFAS
- Certification first. Look for a model certified under NSF/ANSI 53 (filters) or NSF/ANSI 58 (reverse osmosis) with a PFOA/PFOS reduction claim.
- Check the exact model in the certifier's online listing, not just the brand.
- Follow the replacement schedule. A filter past its rated capacity no longer meets its claim.
Living Water does not claim that its systems remove PFAS. If PFAS reduction is your goal, Jorge will tell you to look for that specific certified claim.
Where Jorge fits in
An in-home screening does not measure PFAS; that takes a specialized laboratory. Jorge's free visit is about taste, odor, hardness, iron and dissolved solids, and about helping you read your utility's report. If PFAS is your main concern, a certified lab test and a certified filter are the right tools.
