PFAS Testing Services
Per–and Polyfluoroalkyl substances, known by many acronyms (PFOA, PFOS, C-8, now collectively being referred to as PFAS and "Forever Chemicals") are present in many common commercial and household items, including nonstick kitchenware, fabrics, cosmetics, firefighting foam, and more.
DoD facilities, chemical plants and fire stations are where most PFAS investigations have been focused, but with the CDC indicating that measurable levels of PFAS are likely found in the bloodstream of every American, and concerning health effects still being studied, many PFAS experts say we’ve only scratched the surface of this issue.
ARA's scientists and partners are committed to staying on top of the latest scientific information, methods, limits and changes, so that you can focus on your projects knowing you have the best PFAS resource in your corner. If you have any questions about PFAS testing, how to test for PFAS, or where PFAS is found, give us a call or send an email today.
ARA provides drinking water analysis for PFAS via EPA methods 537.1, and 533. We also offer a "modified 533" option for PFAS analysis via LC-MS/MS, using quantitation by isotope dilution. This method employs a solid phase extraction (SPE) followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the determination of select per- and polyfluoroalkyl substances (PFAS) in non-potable water matrices.
*Coming Soon: EPA Method 1633
IMPORTANT:
Never use "Blue Ice" / gel refrigerants / cold packs to chill PFAS samples. Always chill PFAS samples with real ice.

Sample integrity is of the utmost importance when collecting your PFAS samples. Please help avoid trace or cross contamination of PFAS by adhering to the guidelines set forth by your state environmental services department. The NHDES PFAS sampling guidelines can be found here:
https://www4.des.state.nh.us/nh-pfas-investigation/wp-content/uploads/2019/05/201905_Sample-Collection-Guidance-2.pdf
Residential customers please note: ARA is a New Hampshire-based lab, and we are not certified to accept drinking water samples outside of New England.
If you want to know how to test for PFAS in water or would like a PFAS Testing Kit, contact ARA with questions.
Not everyone needs to test for PFAS. Follow your state’or town's water testing guidelines, If you are near a contaminated site, or have a specific concern, you can and should request additional testing.
As always, ARA encourages everyone with a private well to test their water every few years, regardless of what’s going on in the news. If you have concerns about PFAS or would like to know how to test your water for PFAS (PFOA, PFOS, C8, etc.), contact ARA with questions.
PFAS are a class of man-made chemicals which have been widely used to make products more stain-resistant, waterproof and/or nonstick, such as:
- non-stick cookware
- stain-resistant furniture, carpets, clothing
- waterproof shoes, clothing, mattresses
- non-stick food packaging
- firefighting foam
