Key Takeaways:

• What They Are: PFAS are "forever chemicals" from industrial products that don't break down and have contaminated many DFW water sources.
• New EPA Rules: In 2024, the EPA set a new, very strict legal limit for PFAS in drinking water (4 parts per trillion) due to serious health risks.
• Most Filters Don't Work: Standard refrigerator, pitcher, and even whole-home carbon filters are not effective at removing PFAS to the new safe levels.
• The Best Solution: The EPA confirms that Reverse Osmosis (RO) is one of the most effective and proven home technologies to physically block and remove PFAS molecules, providing a final barrier of protection.

PFAS, or per- and polyfluoroalkyl substances, are a group of thousands of man-made chemicals that are now a significant water quality concern in North Texas and across the country.

They are often called "forever chemicals" because their strong chemical bonds prevent them from breaking down naturally in the environment or in the human body.

Where Do PFAS Come From?

For decades, PFAS have been used in a vast range of industrial and consumer products due to their resistance to heat, water, and oil. Common sources include:

• Non-stick cookware (like Teflon)
• Water-repellent and stain-resistant fabrics (like Gore-Tex and Scotchgard)
• Food packaging (e.g., microwave popcorn bags, fast-food wrappers)
• Firefighting foam used at airports and military bases.

Over time, these chemicals have contaminated our soil, air, and water supplies.

The New EPA Regulations and Health Concerns

In April 2024, the EPA finalized the first-ever national, legally enforceable drinking water standard for PFAS. The new Maximum Contaminant Levels (MCLs) are set at extremely low levels, near what is detectable:

• 4.0 parts per trillion (ppt) for PFOA and PFOS, the two most well-studied compounds.

This new regulation reflects the serious health concerns linked to long-term exposure, which include developmental effects in children, immune system disruption, hormonal interference, and an increased risk of certain cancers.

PFAS in DFW Water

Testing by environmental groups and municipalities has confirmed the presence of various PFAS compounds in many DFW-area water supplies. While cities are now mandated to upgrade their treatment facilities, this will take years and significant investment. This leaves many families seeking an immediate, reliable solution for their own homes.

The Most Effective Solution: Reverse Osmosis

It is critical to understand that most common filters are not effective at removing PFAS.

• Refrigerator & Pitcher Filters: These basic carbon filters cannot meaningfully reduce PFAS to the new safe levels.
• Water Softeners & Standard Whole-Home Filters: These systems are not designed to target PFAS.

The EPA and the Water Quality Association confirm that a high-quality Reverse Osmosis (RO) system (with USA-made options available) is one of the most effective and proven residential technologies for drastically reducing PFAS.

Why RO Works:

An RO system forces water through a semi-permeable membrane with pores so small that they can block the complex, long-chain PFAS molecules, along with other contaminants like lead and arsenic. It provides a final, physical barrier of protection for the water your family drinks and cooks with, ensuring it meets and exceeds the new safety standards.
