What’s the tea? The EPA is weakening drinking water rules for PFAS

[00:00:00]Mhm.

[00:00:01]So, the EPA's proposing a rollback protections against toxic chemicals in your drinking water. Here's what you can do about it. This is What's the Tea with EWG, bringing you the latest in public health news. PFAS, aka forever chemicals, are used in things like nonstick pans, waterproof clothing, and pesticides. They're called forever chemicals because they don't really break down in the environment, and some can build up in our bodies over time.

[00:00:20]Studies have linked PFAS exposure to serious health harms like cancer, immune system harm, fertility issues, and developmental concerns in kids. In 2024, the EPA finalized the first ever national drinking water limits for several PFAS chemicals. It was a pretty big step forward. But now, the agency is weakening those protections by delaying the compliance deadline for PFOA and PFOS, which are the most common PFAS contaminants, and they're straight-up eliminating the limits for four other PFAS chemicals altogether. And one of the most frustrating parts is that PFAS contamination is really widespread. More than half of the US population has PFAS in their water, and 176 million Americans drink tap water contaminated with PFAS.

[00:00:58]So, let's go ahead and answer the question we've all been asking ourselves. What can I actually do to remove PFAS from my tap water? Well, one of the best ways to reduce exposure to PFAS in your tap water is by filtering it. Reverse osmosis filters are the most effective for filtering out PFAS, although they can be a bit pricey. Most carbon-based filters also absorb contaminants like PFAS, and they're usually the more accessible and affordable option. You can also check EWG's tap water database and enter your zip code to see if PFAS or any other contaminants have been detected in your local water supply. We need nationwide standards to ensure that all water is safe and clean. But for now, practical steps at home can make all the difference.
