If you’ve been paying attention to the news about PFAS in drinking water, you may have heard that the Environmental Protection Agency (EPA) recently changed some of its regulations around these chemicals. At Dupure, we know this topic can feel overwhelming—and that most families just want one thing: safe, clean water they can trust.

In this post, we’ll walk you through what PFAS are, why the EPA’s updated guidelines matter, and what steps you can take to protect your home and your health.

What Are PFAS?

Let’s start with the basics. PFAS (per- and polyfluoroalkyl substances) are a group of man-made chemicals used since the 1940s in a wide range of industrial and consumer products. They’re found in everything from nonstick cookware and food packaging to water-resistant clothing and firefighting foams.

What makes PFAS so concerning is that they don’t break down easily in the environment or the human body. That’s why they’re often called “forever chemicals.” Once PFAS enter your drinking water—or your bloodstream—they can linger for years.

Why Should You Be Concerned About PFAS in Your Water?

Multiple studies have linked PFAS exposure to serious health problems, even at very low levels. These include:

• Increased risk of certain cancers
• Liver and kidney damage
• Hormonal disruptions
• High cholesterol
• Weakened immune system
• Developmental issues in infants and children

PFAS can enter your water supply through contaminated industrial sites, military bases using firefighting foams, and even landfill runoff. Because they’re so stable, traditional water treatment methods often can’t remove them.

The EPA’s Updated PFAS Regulations in 2025

In 2024, the EPA finalized its first-ever national standards for PFAS in drinking water, aiming to hold water systems across the U.S. accountable for monitoring and reducing six specific PFAS compounds:

• PFOA
• PFOS
• PFHxS
• PFNA
• GenX (HFPO-DA)
• PFBS

These rules were a big step forward for public health. But in 2025, the EPA announced changes to the initial guidelines, including:

1. Maintaining Strict Limits for PFOA and PFOS

The EPA reaffirmed the Maximum Contaminant Levels (MCLs) for PFOA and PFOS at 4 parts per trillion (ppt), which is the lowest level current technology can reliably measure. These two compounds have been studied the most and are considered the most harmful.

2. Removing National Limits for Four Other PFAS

The EPA rescinded enforceable limits for four additional PFAS (PFHxS, PFNA, GenX, and PFBS). Instead, water systems are encouraged—but not required—to monitor or treat for these compounds.

3. Extending Compliance Deadlines

Water utilities now have until 2031 to fully comply with the federal standards for PFOA and PFOS. That’s two years later than originally planned, which gives municipalities more time to install treatment systems—but also delays action for customers.

What Does This Mean for You?

The big takeaway is this: just because your water provider is compliant with federal standards doesn’t necessarily mean your water is PFAS-free.

Many utilities now have more time—and less obligation—to act. If you live near a potential PFAS contamination site (like an industrial zone or military base), or if your city’s water system hasn’t invested in advanced filtration, you may be unknowingly drinking water with PFAS.

At Dupure, we believe families shouldn’t have to wait on policy or bureaucracy to protect their health. You deserve clean water now—not six years from now.

How to Protect Your Family from PFAS

The good news is that you’re not powerless. While PFAS are hard to remove with standard filtration, certain technologies can significantly reduce PFAS levels at the point of use or point of entry in your home.

1. Test Your Water for PFAS

Start by finding out what’s in your water. You can check your municipality’s water quality report or request a PFAS test from a certified lab. If you use a private well, it’s especially important to test regularly.

2. Use Certified Water Filtration Systems

Look for NSF-certified filtration systems that are proven to reduce PFOA and PFOS. Technologies such as:

• Reverse Osmosis (RO): Removes a broad range of PFAS compounds.
  
• Whole-Home Systems: For those seeking full-house protection, these systems treat all water entering the home.

Dupure’s RO systems and advanced under-sink filters are engineered to reduce PFAS along with many other contaminants—giving you clear, clean drinking water straight from the tap.

3. Stay Informed

Regulations around PFAS are still evolving. Stay connected with trusted sources like Dupure, the EPA, and your local water authority so you’re never caught off guard by changes.

Frequently Asked Questions About PFAS

Q: Are PFAS in bottled water too?
A: Sometimes. PFAS have been found in some bottled waters, especially those not using advanced filtration. Always check the brand’s testing data.

Q: Will boiling water remove PFAS?
A: No. Boiling actually concentrates PFAS. Only advanced filtration technologies like RO or activated carbon will help.

Q: How often should I test my water?
A: If you’re concerned about PFAS or other contaminants, test at least once a year—or immediately if new construction, flooding, or contamination is suspected in your area.

The Bottom Line: PFAS Require Proactive Protection

PFAS aren’t going away anytime soon. And while the EPA is making strides to regulate these chemicals, the changes in 2025 make it clear that you can’t rely on regulations alone.

At Dupure, we believe knowledge is power—and water is life. By understanding what PFAS are and how to remove them, you can make smart, confident decisions about your family’s water.

Your water should be as clean as your home—and we’re here to make sure it is.
