PFAS TESTING
How Much Does PFAS Testing Cost? (2026 Price Guide)
A PFAS test can cost $20 or $400 depending on what you buy. Here is what each price range actually gets you, and when it is worth paying more.

PFAS testing cost breakdown
| Test type | Cost range | What you get |
|---|---|---|
| DIY PFAS strip test | $20 to $40 | Rough screen only. Not certified. Cannot reliably detect PFAS at EPA-relevant levels. |
| Mail-in basic PFAS | $75 to $150 | 6 to 14 PFAS compounds. Certified lab. Good for first-time testing. |
| Mail-in comprehensive PFAS | $150 to $300 | 32+ compounds including PFBS, PFNA, PFHxS, GenX. EPA Method 533 or 537.1. |
| State-certified lab (local) | $50 to $200 | Varies by state. Required for legal purposes. May offer faster turnaround. |
| Full well water panel (PFAS plus other) | $200 to $400 | Most complete picture. PFAS plus bacteria, nitrates, metals, and more. |
| Annual retesting | $150 to $250 | Track changes over time. Use same lab for consistent comparisons. |
When to spend more on testing
Pay for a comprehensive 32-compound panel if you are within 10 miles of a military base, an airport with fire training areas, a chemical plant, or a former industrial site. These locations used PFAS-containing firefighting foam or industrial chemicals. Basic panels only catch PFOA and PFOS. Newer PFAS compounds show up only in comprehensive panels.
If cost is tight and you are not near a known source, a basic 6 to 14 compound panel catches the most common contaminants. You can always upgrade later.
What the EPA 2027 rule means for testing costs
In April 2024, the EPA finalized its first-ever PFAS drinking water rule. It sets limits of 4 parts per trillion for PFOA and PFOS in public water systems. The compliance deadline for utilities is 2027.
Private wells are not covered. But the rule has already changed the testing market. More labs are now certified for EPA Method 533 and 537.1. Supply is up, and prices for PFAS testing have come down compared to 2021 and 2022 when certified labs were harder to find.
The 4 ppt limit also gives well owners a clear benchmark. Before the 2024 rule, there was no federal number to compare your results to.
State vs national lab: does it matter?
Both options use certified labs. The main differences are turnaround time and cost. Local state labs can sometimes offer faster results for residents who need them for a legal or real estate deadline. National mail-in labs like SimpleLab are often more convenient and deliver better-formatted reports.
For most private well owners, a national mail-in service is the easiest option. For anything legal, check that the lab holds certification in your specific state.
Free state testing programs
Several states fund free or subsidized PFAS testing for private well owners. Programs change based on budget cycles, so call your state health department to confirm availability.
Michigan
EGLE runs a private well testing program for residents near confirmed PFAS contamination sites. Free testing is available for qualifying wells.
Vermont
Vermont DEC offers free PFAS testing for private wells within a certain distance of known discharge locations. Vermont has some of the strictest state PFAS limits in the country.
New Jersey
NJDEP offers free testing for private wells near Superfund sites and other priority contamination areas. Check the NJDEP private well testing program page.
Minnesota
MDH offers subsidized testing for low-income well owners and free testing in designated contamination areas.
North Carolina
NC DHHS ran a GenX-related testing program in the Cape Fear region. Check with NCDHHS for current availability.
Frequently asked questions
What is the cheapest way to test for PFAS in water?
DIY strip tests cost $20 to $40 but do not actually detect PFAS accurately. The cheapest reliable option is a basic mail-in PFAS panel at $75 to $150. Check your state health department first because some states offer free testing for private well owners.
Does insurance cover PFAS water testing?
Generally no. Standard homeowner policies do not cover water quality testing. However, if you live near a known contamination site, there may be a legal settlement fund or state remediation program that covers testing costs. Check with your county health department.
What is the difference between a basic PFAS test and a comprehensive one?
A basic panel tests for PFOA and PFOS, the two most regulated PFAS compounds. A comprehensive panel tests 32 or more PFAS compounds, including newer ones like PFBS, PFNA, PFHxS, and GenX. If you are near an industrial site or military base, get the comprehensive panel.
Do I need to retest every year?
Every three years is the standard recommendation for PFAS in private wells. Test sooner if you are near a new contamination site, if your local utility issues a notice, or if your state adopts new PFAS monitoring rules.
