PFAS Testing Services

Per–and Polyfluoroalkyl substances, known by many acronyms (PFOA, PFOS, C-8, now collectively being referred to as PFAS and "Forever Chemcials") 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 is your resource for NH PFAS testing. 

ARA provides drinking water analysis for PFAS via method 537.1 for the following compounds, and we partner with specialty labs for other methods and compounds, so just let us know if what you need is not on this list.

Please note: 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:

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 are not within a reasonable driving distance of our lab in Portsmouth, NH, please visit the Department of Environmental Services website for your state to find a certified lab in your geographical area.

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. You should follow your state’s water testing guidelines, and only if you are near a contaminated site, or have a specific concern, you should test for those additional items as well. As always, ARA encourages everyone with a private well to test their water every few years as a rule of thumb, regardless of what’s going on in the news. (Watch this short video to see how easy it is to get your water tested).  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
