PFAS in Tap Water and Your Home: Everything You Need to Know About Exposure
From your tap to your nonstick pan, forever chemicals are closer than you think.
PFAS — the “forever chemicals” linked to serious health concerns — are getting harder to ignore. Federal rollbacks have shifted the burden onto consumers, and the EWG estimates more than 200 million Americans could be drinking tap water with PFAS above 1 part per trillion.
Knowing whether they’re in your water — and where else they’re hiding in your home — is something most households now need to figure out for themselves.
How to check your tap water for PFAS
Start free. The EWG Tap Water Database lets you enter your ZIP code and see which contaminants your utility has detected, compared against both federal limits and stricter health-based guidelines. Keep one caveat in mind: it reflects testing at the treatment plant, not necessarily what comes out of your specific tap. You can also request your utility’s annual Consumer Confidence Report, required by law and available online. If results show PFAS as “not detected,” that may mean the system hasn’t been tested yet — not that the chemicals aren’t there.

When a home PFAS test kit is worth it
Private well owners should test at least annually since wells aren’t regulated by the EPA. Households near military bases, airports, industrial sites or agricultural areas have strong reasons to test too. No test strip or TDS meter can detect PFAS — you need a mail-in lab kit. Tap Score is recommended by Wirecutter and tests 14 PFAS compounds for $335. SimpleLab offers similar options. When collecting, run the tap two to three minutes first and use only the sterile bottle provided.

Where PFAS hides beyond your tap
PFAS show up across the modern household — not just in water. PTFE, the nonstick coating known as Teflon, is itself a PFAS, and scratched pans increase leaching risk. Minnesota banned PFAS cookware as of January 2025; Colorado, Connecticut, Maine and Vermont followed in January 2026.
Fast-food wrappers, microwave popcorn bags and pizza boxes were historically treated with PFAS. The FDA confirmed those agents are no longer sold in the U.S. as of February 2024, though existing packaging may still contain them. Most rain jackets and shells sold in the U.S. now use PFAS-free coatings as of 2026, but gear bought before 2025 may still contain them. PFAS also turn up in stain-resistant carpet treatments, some cosmetics and certain dental floss brands, and accumulate in household dust.
Simple swaps to cut your PFAS exposure
Replace scratched nonstick pans with stainless steel, cast iron or certified PTFE-free alternatives. Transfer food out of fast-food containers before reheating and use glass or ceramic instead. When replacing outdoor gear, look for PFAS-free DWR labels or bluesign certification — Patagonia went fully PFAS-free in spring 2025.
Skip stain-resistant carpet treatments and vacuum with a HEPA filter regularly. For cooking water, a countertop RO system or NSF P473-certified filter at the kitchen tap covers pasta, rice and soups too — not just drinking water. EPA Safer Choice-certified products are a reliable screen for PFAS-free cleaning sprays.
