PFAS ('forever chemicals') have been detected in some DFW municipal water supplies at levels that prompted EPA scrutiny under the 2024 drinking water standards. Point-of-use filtration — specifically certified reverse osmosis systems — is the most effective household response.
PFAS (per- and polyfluoroalkyl substances) entered the public awareness sharply after the EPA finalized maximum contaminant levels (MCLs) in 2024. Here's what DFW homeowners actually need to know without the noise.
What PFAS Are
PFAS are a family of thousands of synthetic chemicals used in nonstick coatings, firefighting foam, food packaging, and many industrial applications. They're called "forever chemicals" because they don't break down naturally in the environment or in the human body. PFOA and PFOS are the most studied and most regulated variants.
DFW Water Supplies and PFAS
The major DFW water utilities — North Texas Municipal Water District, Dallas Water Utilities, Fort Worth Water — have conducted testing under EPA mandate. Some sources have shown PFAS at low but detectable levels. The 2024 EPA standards set MCLs for PFOA and PFOS at 4 parts per trillion — a very low threshold that required extensive testing. Check your utility's annual water quality report (Consumer Confidence Report) for current PFAS data specific to your address.
What Point-of-Use Filtration Does
Certified reverse osmosis (RO) systems with NSF/ANSI 58 or NSF/ANSI 53 certification remove PFAS effectively at the point of use — typically under the kitchen sink for drinking and cooking water. Pitcher filters (Brita, etc.) are not effective against PFAS. Whole-house carbon filters reduce but don't eliminate PFAS.
