What PFAS are
PFAS (per- and polyfluoroalkyl substances) are chemicals used in products like non-stick coatings, stain-resistant fabrics and some firefighting foams. They break down very slowly, which is why EPA studies and regulates them in drinking water. EPA's PFAS pages explain the current federal rules.
Where to see Miramar's results
The City of Miramar's 2024 Water Quality Report describes UCMR 5, which required sampling for 29 PFAS and lithium between 2023 and 2025, and says the city must publish analytical results of detected unregulated contaminants in its annual report. Read the newest report at miramarfl.gov/waterquality, or call customer service at 954-602-HELP (4357) and ask for the UCMR 5 results for your plant.
EPA also publishes UCMR 5 data by water system on its UCMR 5 page.
How to judge a PFAS filter
- Look for certification to NSF/ANSI 53 (filters) or NSF/ANSI 58 (reverse osmosis) that specifically lists PFOA and PFOS reduction.
- Check the exact model number on the certifier's listing, not just the brand.
- Follow the replacement schedule; a spent filter does not perform as certified.
Living Water does not claim its systems remove PFAS. If PFAS reduction is your goal, Jorge will tell you to verify any model's certification before you buy, including anything he shows you.
Miramar's membrane treatment
Miramar's plants use nanofiltration, and the West plant adds reverse osmosis. Membrane processes are used in water treatment for many purposes, but the only reliable way to know what is in your tap water is the utility's reported data. Do not assume either way; read the results.
Private wells and PFAS
The City of Miramar's page on its Country Club Ranches water project notes that EPA has identified contaminants, including PFAS, that can be found in private wells, and that well owners are responsible for testing their own water. If you are on a well and PFAS is a concern, a certified lab test is the only way to know.
Testing PFAS at home
PFAS testing requires a certified laboratory using EPA methods. Jorge's free in-home screening covers everyday parameters like chlorine, hardness, TDS and iron; he can help you understand your report and your options. Call, text or WhatsApp (305) 793-5974. See also home screening vs. lab analysis.
