PFAS-Free Faux Grass (2026): What "PFAS-Free" Really Means and How to Check a Claim
A "PFAS-free" label on faux grass means little until you know which test was used and how sensitive it was.
PFAS, often called "forever chemicals", are a large family of fluorine-based compounds. They can be used as processing aids when plastic turf fibres are made, which is one way they can end up in turf. A "PFAS-free" claim is only as good as the test behind it. Some tests look for a short list of compounds and can miss others. Some have detection limits so high that they'd miss low levels.
This guide explains why PFAS shows up in turf, how the two main kinds of test differ and how to check a claim. We drew on news reporting from E&E News and The Philadelphia Inquirer, advocacy and research summaries from the Collaborative for Health & Environment, the Ecology Center and PEER, and a University of Massachusetts Lowell compilation of turf tests. Advocacy data is labelled as such. We don't make health claims beyond these sources. We didn't find an official US "PFAS-free turf" standard, and PFAS rules are changing, so check your state's current laws.
Why is PFAS found in faux grass?
Testing by cities and advocacy groups has repeatedly found fluorine in turf fibres.
PFAS-based processing aids help plastic flow smoothly when it's extruded into fibres. Traces can remain in the finished product. That's one reason testing has found fluorine in turf, even where PFAS isn't added on purpose.
| Case | What was found | Source |
|---|---|---|
| Advocacy testing, 2020 | Fluorine in all synthetic turf fibre samples tested, at 44 to 255 ppm (advocacy data) | Ecology Center letter in Hamilton, Mass., municipal records |
| Portsmouth, New Hampshire | Organic fluorine found in turf testing; PFOS reported at 135 ppt in one result | E&E News |
| Philadelphia fields | Testing at FDR Park and Murphy Rec raised questions about detection limits far above those used for drinking water | The Philadelphia Inquirer |
| South Philadelphia field | Advocacy group PEER publicised PFAS concerns | PEER |
The industry disputes some of these conclusions. A Tucson TV station, for example, aired an industry businessman's view. And some turf companies have sent letters to towns stating results below 100 parts per trillion for targeted PFAS tests.
Does artificial turf contain PFAS? Testing has found fluorine, a marker for PFAS, in many turf samples. Whether a specific product contains PFAS depends on how it was made, which is why the test method matters.
Targeted PFAS tests vs total organic fluorine
A targeted test only finds what it looks for; a total fluorine test looks for everything with fluorine.
| Targeted PFAS test | Total organic fluorine (TOF) | |
|---|---|---|
| What it measures | A set list of specific PFAS compounds | All fluorine bound to carbon, which includes PFAS |
| Strength | Identifies exact compounds | Catches PFAS that aren't on any list |
| Weakness | Misses any PFAS not on the list | Doesn't say which compounds are present |
| Common pitfall | "Non-detect" can mean the list didn't include what's there, or the detection limit was too high | Needs a sensitive lab method to be useful |
The Collaborative for Health & Environment stresses that a "non-detect" on a targeted test doesn't prove a product is PFAS-free. It recommends total organic fluorine as a broader screen. The Inquirer's Philadelphia reporting showed how high detection limits can let PFAS go undetected. Another broad method, the total oxidizable precursor (TOP) assay, converts hidden PFAS into measurable forms.
For context, UMass Lowell has published a compilation of PFAS test results from turf, which is a useful reference for comparing claims.
How do you test artificial turf for PFAS? With a sensitive total organic fluorine test, ideally alongside a targeted test, done by an independent lab on a sample of the actual product.
Why can a PFAS-free test be misleading? Because a targeted test may not look for the PFAS that's there, or its detection limit may be too high to see it.
How do you check a seller's PFAS-free claim?
Ask for the total organic fluorine result and its detection limit. Use this checklist:
- Ask for TOF results. A total organic fluorine result is the most useful single figure.
- Ask for the detection limit. A "non-detect" means little if the limit was high.
- Ask for the lab's name. It should be an independent lab, not the seller.
- Ask for the date. Products and suppliers change.
- Check the sample matches. The test should be on the exact turf you're buying, not a related product.
- Be cautious with targeted-only claims. A claim like "below 100 ppt" for a short list of compounds, without method details, leaves gaps.
- Compare with published data. UMass Lowell's compilation helps put results in context.

PFAS-conscious turf options
Choose brands that publish their full testing, or consider a living alternative.
We didn't find any Amazon turf listing that published total organic fluorine results when we checked. Several say "non-toxic" or "lead-free", but that's a different claim, and none showed PFAS testing. So we're not recommending any product as PFAS-free here.
Our take: our hands-on work with artificial grass tells us a lot about how turf looks, feels and wears, but nothing about its chemistry. You can't see, smell or feel PFAS, so on this question the independent lab report is the only evidence that counts. Until a seller can show a total organic fluorine result for the exact product, we'd treat a "PFAS-free" badge as a claim to verify, not a guarantee.
So if PFAS is a concern, you have three options:
- Ask dealers for full testing. Some turf brands sold through dealers say they test for PFAS. Ask for the TOF result, detection limit and lab, using the checklist above. See faux grass brands.
- Choose a living lawn. Real grass avoids the question entirely, though it needs water and mowing. See faux grass vs real grass.
- Consider a low-water alternative. Clover lawns and xeriscaping cut water use without plastic. See faux grass vs clover lawn and faux grass vs xeriscaping.
PFAS questions
Is there an official PFAS-free label for turf? We didn't find a US government standard for "PFAS-free" turf. Treat the label as a seller claim and ask for testing.
Are PFAS rules changing? Yes. Several US states have been passing laws on PFAS in consumer products, and rules are evolving. Check your state's current requirements, especially for schools and public spaces.
