A Big Change Is Coming to Your Drinking Water
If you’ve never heard of “forever chemicals,” you’re not alone—but you’ve probably consumed them. These substances, formally known as PFAS (per- and polyfluoroalkyl substances), are found in everything from nonstick cookware to waterproof jackets—and yes, even in drinking water.
Now, for the first time ever, the Environmental Protection Agency (EPA) is setting nationwide limits on six of the most dangerous PFAS chemicals in public water systems. The move could reshape water safety across the U.S., protecting millions from long-term health risks.
What Are Forever Chemicals—and Why Are They a Problem?
PFAS chemicals are called “forever” because they don’t break down easily in the environment or in the human body. Over time, they build up—and that’s where the danger lies.
Research has linked long-term PFAS exposure to:
- Certain cancers (especially kidney and testicular)
- Liver and thyroid problems
- Immune system suppression
- High blood pressure in pregnancy
- Low birth weight in babies
These chemicals have been used since the 1940s, and while many have been phased out, they’re still widely present in water, soil, food, and even the blood of most Americans.
What the New EPA Rule Means for You
Under the new EPA rule, public water systems will be required to test for six types of PFAS and reduce them to very low levels—just 4 parts per trillion in some cases. Water systems have until 2029 to comply, although many areas may start sooner.
This is a major shift from past standards, where PFAS testing was optional, and acceptable levels were far higher. The EPA says this rule could prevent thousands of illnesses and deaths related to long-term PFAS exposure.
If your local water utility exceeds the limits, they’ll need to install treatment systems or find new water sources—potentially a costly but critical investment in public health.
How to Protect Your Family Right Now
Even before the rule takes full effect, there are steps you can take to reduce PFAS exposure at home:
- Check your local water report. Your utility is required to share what contaminants are present.
- Use a certified water filter. Look for ones that say they’re effective against PFAS—reverse osmosis and activated carbon filters are best.
- Avoid stain- and water-resistant products that may contain PFAS, especially cookware, carpets, and food packaging.
- Stay informed. Advocacy groups like EWG (Environmental Working Group) offer searchable databases to check PFAS levels by ZIP code.
This new EPA rule marks a turning point in how we think about everyday chemical exposure. While the cleanup will take time, the long-term payoff is a safer, healthier future—especially for families who rely on tap water every day.
