PFAS Testing Services

Per–and Polyfluoroalkyl substances, known by many acronyms (PFCs, PFOA, PFOS, and now collectively being referred to as PFASs) are present in many common commercial and household items, including nonstick kitchenware, fabrics, cosmetics, lotions and more. Studies have shown that exposure over certain levels may cause very serious health issues in humans.


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. 


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


ARA has partnered with a specialty laboratory to provide a PFAS water analysis "package" for the following 19 compounds, referred to as PFAS UL 19:


  • Perfluorobutanoic acid PFBA
  • Perfluoropentanoic acid PFPeA
  • Perfluorohexanoic acid PFHxA
  • Perfluoroheptanoic acid PFHpA
  • Perfluorooctanoic acid PFOA
  • Perfluorononanoic acid PFNA
  • Perfluorodecanoic acid PFDA
  • Perfluoroundecanoic acid PFUnA
  • Perfluorododecanoic acid PFDoA
  • Perfluorotridecanoic acid PFTrDA
  • Perfluorotetradecanoic acid PFTeDA
  • Perfluorobutanesulfonate PFBS
  • Perfluorohexanesulfonate PFHxS
  • Perfluoroheptanesulfonate PFHpS
  • Perfluorooctanesulfonate PFOS
  • Perfluorodecanesulfonate PFDS
  • Perfluorooctanesulfonamide PFOSA
  • 6:2 Fluorotelomersulfonate 6:2 FTS
  • 8:2 Fluorotelomersulfonate 8:2 FTS


PFAS Sample Collection

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.
  • 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.
  • Our lab is located at 124 Heritage Ave, #16, Portsmouth, NH. Phone: 877.320.7373


Water Quality in the News

Many states are struggling with their own water quality issues, and NH is no different. From PFAS, arsenic and THMs in the water, to Pease, Saint Gobain and an unexplained “cancer cluster” on the NH seacoast, lately it seems that the news releases coming from the New Hampshire Department of Environmental Services (NHDES) office in Concord cannot keep up with the public’s thirst for information and reassurance that their drinking water quality and our environment are safe. Here are just a handful of hundreds of NH news stories related to water quality:
