Are PFAS in Your Tap Water? How to Test Your Home and Get Rid of Hidden Forever Chemicals
Most Americans now know PFAS exist, but few know how to actually check their own water — or where else in the house exposure might be coming from. With federal protections in flux and the EWG estimating more than 200 million Americans could have PFAS in their drinking water above 1 part per trillion, the responsibility has largely shifted to consumers to figure this out themselves. Here’s how to do it.
How Do You Check Your Tap Water for PFAS Right Now for Free?
Start with the EWG Tap Water Database — a free tool that lets you enter your ZIP code and see what contaminants your utility has reported, measured against both federal limits and stricter health-based guidelines.
One important caveat: the database reflects testing at treatment plants, not necessarily what’s coming out of your specific tap. You can also request your utility’s annual Consumer Confidence Report, which is required by law and typically available online.
If your report shows PFAS as “not detected,” that may mean your system hasn’t been tested yet, not that PFAS aren’t present. The federal UCMR 5 testing program ran through 2025 and not every system has reported results.
And a quick note on what doesn’t work: no test strip, color-change kit or TDS meter can detect PFAS. These chemicals show up at parts-per-trillion concentrations that require specialized lab equipment. If a product claims to screen for PFAS with a strip, it isn’t doing what it says.
When Is a Home Lab Test Worth It — and Which Kits Actually Work?
A paid lab test makes sense if you’re on a private well, live near a military base, airport, industrial site or agricultural area, or your utility hasn’t yet reported PFAS results. Private wells aren’t regulated by the EPA or covered by utility testing, and the EPA and CDC recommend testing them at least once a year.
Mail-in kits are your only reliable option. Two widely vetted choices:
- Tap Score — $335 for 14 PFAS compounds using EPA Method 537.1, recommended by Wirecutter, results in about 10 business days
- SimpleLab — similar scope and price range, uses EPA-certified labs, good option if you want bundled contaminant testing
Collection matters as much as the lab itself. Run your tap for two to three minutes before sampling, use only the sterile bottle the kit provides and keep the sample away from nonstick cookware or PFAS-treated surfaces. Cross-contamination can skew your results.
One detail worth flagging: most people filter drinking water but cook pasta, rice and soups in unfiltered tap. If you’re going to invest in filtration, make sure it covers the kitchen tap too, not just a separate drinking pitcher.
Where Else Could PFAS Be Hiding in Your Home?
PFAS show up far beyond the tap. Here’s where to look:
- Nonstick cookware. PTFE — sold under the Teflon name — is itself a PFAS. Scratched or damaged pans increase leaching risk. Minnesota banned PFAS cookware as of January 2025, and Colorado, Connecticut, Maine and Vermont bans took effect January 2026.
- Food packaging. Fast food wrappers, microwave popcorn bags and pizza boxes were historically treated with PFAS grease-proofing agents. The FDA confirmed those agents are no longer sold in the U.S. as of February 2024, though packaging already in circulation may still contain them.
- Clothing and outdoor gear. Water-resistant DWR coatings on rain jackets, ski gear and activewear have long relied on PFAS chemistry. As of 2026, most rain jackets and shells sold in the U.S. now use PFAS-free chemistry, driven by California’s AB 1817 and New York laws banning intentionally added PFAS in most textiles as of January 2025. Gear for severe wet conditions is exempt until 2028, and anything bought before 2025 may still contain PFAS.
- Carpet, upholstery and household dust. Stain-resistant treatments typically use PFAS, which accumulates in household dust. Vacuuming frequently with a HEPA filter is one of the simplest exposure-reduction steps available.
- Cosmetics and dental floss. Certain mascaras, foundations and lip products contain PFAS as a texture agent, and some dental floss brands have historically used PFAS coatings, per NRDC reporting from September 2025.
What Simple Swaps Can You Make to Reduce PFAS Exposure Starting Today?
You don’t need to overhaul your home overnight. These swaps cover the biggest exposure pathways and most can happen gradually as items wear out.
Replace scratched nonstick pans with stainless steel, cast iron or certified PTFE-free and PFOA-free alternatives. Surface degradation starts before you can see flaking, so a worn pan is worth retiring even if it looks fine.
Transfer food out of fast food containers and microwave bags before reheating — glass or ceramic are the straightforward swap. For cooking water, route a countertop reverse osmosis system or NSF P473-certified filter through the kitchen tap so it covers everything you cook with, not just what you drink.
When you replace outdoor gear or activewear, look for PFAS-free DWR labels or bluesign certification. Patagonia transitioned all waterproof products to PFAS-free chemistry as of spring 2025, and H&M, Levi’s and UNIQLO have committed to PFAS bans across their lines.
Around the house, skip stain-resistant carpet and upholstery treatments and vacuum more frequently with a HEPA filter to cut dust-bound PFAS. For cleaning sprays and fabric protectors, EPA Safer Choice certified products are a useful baseline screen.
None of this requires an overnight overhaul. Replace things as they wear out, filter the kitchen tap, vacuum more and check labels on the next jacket or pan you buy.
