What Is PFAS — And Is It In Your Water?
PFAS are synthetic chemicals used in hundreds of everyday products since the 1940s. Nonstick cookware. Food packaging. Waterproof clothing. Military firefighting foam.
The problem is simple: they don't break down. Not in the environment. Not in your body.
They build up over time. That's why they're called forever chemicals.
How they end up in your tap water
Industrial sites, military bases, and manufacturing facilities have been leaching PFAS into groundwater for decades. That groundwater feeds your water supply.
Your utility treats your water for bacteria and sediment. PFAS isn't on that list. It passes straight through standard municipal treatment and comes out the other side.
The scale of it
The USGS found PFAS in 45% of US tap water samples tested. The EPA puts the affected population at over 200 million Americans.
This isn't an isolated issue. It's the norm.
What the research says
Long-term exposure has been linked to kidney and testicular cancer, thyroid disease, immune suppression, high cholesterol, and developmental problems in children. The EPA now sets limits at 4 parts per trillion — a number that tells you everything about how seriously they're taking this.
PFAS has no taste. No smell. No color. You won't know it's there without testing.
Does a regular filter help?
No. Brita pitchers, fridge filters, and most under-sink carbon filters don't remove PFAS — especially the newer short-chain compounds that have replaced the original formulas.
Reverse osmosis is what the EPA actually recommends. A properly certified RO system removes up to 99% of PFAS. Nothing else comes close at that level.
