PFAS Water Filter in Miami

What PFAS are

PFAS (per- and polyfluoroalkyl substances) are chemicals used in nonstick coatings, stain-resistant fabrics, some firefighting foams and many industrial processes. They break down very slowly, which is why they show up in water supplies across the country. WASD's report lists the likely sources as discharge from manufacturing and industrial facilities, certain consumer products, occupational exposures and certain firefighting activities.

Where to see Miami's PFAS results

WASD's 2024 Water Quality Report includes a section called 2024 Additional Contaminants Monitoring with results for PFOS, PFOA, PFNA, PFHxS and a PFAS Hazard Index. Look at the Main System column, which covers the system serving the City of Miami.

The report explains these results are part of monitoring for new regulations, that the initial three-year monitoring period ends in 2027, and that systems then have until 2029 to address any exceedances. WASD states it has already taken proactive measures. For questions, the report lists WASD's water quality lines, 786-552-4738 and 786-552-4181.

The federal rule is still moving

The U.S. EPA set national drinking water limits for six PFAS in April 2024. In 2025 the EPA announced plans to give utilities more time for PFOA and PFOS, potentially to 2031, and to rescind the limits for several other PFAS. Because those changes are still in process, check the EPA's PFAS drinking water page for current status rather than relying on any one article.

How to judge a PFAS filter

• Look for certification to NSF/ANSI 53 (filters) or NSF/ANSI 58 (reverse osmosis) for PFOA and PFOS reduction specifically.
• Check the exact model number on the certifier's listing. A brand being certified for one product does not cover all of them.
• Confirm the replacement schedule the certification was tested under. A filter used past its rated life will not perform as listed.
• Be skeptical of general claims like "removes chemicals" without a listing behind them.

The EPA's guide to identifying certified PFAS filters links directly to those listings.

How Jorge helps

Living Water does not claim its systems remove PFAS. What Jorge can do is show you where your utility's results are, explain the certifications to look for, and test the things his in-home test covers, such as disinfectant and hardness. If you want a PFAS result for your own tap, a state-certified laboratory is the right tool. Call, text or WhatsApp (305) 793-5974.
