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. 


Since you cannot see, taste, or smell PFAS, or many of the things that may contaminate your drinking water / affect your water quality, the only way to know if your well water is safe to drink is to have it tested by a certified laboratory. 


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. 


Absolute Resource Associates of Portsmouth offers water analysis packages for PFAS testing (PFOA/PFOS/C8) and many other harmful water contaminants such as lead, arsenic, nitrate/nitrite, bacteria and more.


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.

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 following guidelines:


  • All sources of Teflon™ should be avoided during sample collection and storage.
  • Avoid use of personal products before sampling (cosmetics, moisturizers, deodorant, sunscreen, bug spray, etc. may contaminate your samples).
  • Avoid synthetic, waterproof, or stain resistant clothing/materials while sampling.
  • Thoroughly wash and dry hands before collecting samples.
  • Anyone within 2 meters of collection area should follow the above guidelines, or move out of the sampling area until completion.
  • Use gloves provided in sampling kit only.
  • Use bottles provided in sampling kit only. Samples must be collected in polypropylene or polyethylene (HDPE) bottles fitted w/ unlined (no Teflon™) polypropylene screw cap.
  • Fill bottle to neck and cap it.
  • Immediately place bottle(s) in ziplock bag or cooler with ice. (Do not use 'blue' / chemical-based ice packs, but real ice cubes). 
  • Chill, but do not freeze samples.
  • Do not use chemical (“blue”) ice packs to chill samples.
  • Ensure minimum exposure to light after collection.
  • Fill out chain of custody (COC) form, and drop it off with samples at the lab within 24 hrs.

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
