Our typical PFAS analysis turnaround time, TAT is 10 business days.

*Contact the lab for current TAT information

*Rush TAT may be available for an additional fee

 

We perform your PFAS analysis on site at our lab in Portsmouth, NH (no subcontracting fees).

ARA provides Laboratory Analytical Services to identify and quantify PFAS in environmental samples for municipalities, state agencies, industrial clients and homeowners throughout New England. 

 

ARA is certified for PFAS analysis in drinking water by EPA methods 537.1 and 533. We also offer PFAS via our proprietary LC-MS/MS (isotope dilution) method for groundwater or other water samples (not for drinking water compliance). Method 1633 coming soon.

 

Our proprietary method option for PFAS analysis via LC-MS/MS, uses quantitation by isotope dilution employing 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.

 

PFAS Regulation is currently being evaluated by the EPA.

State PFAS rules and limits will remain in effect until further notice. 

Visit individual state websites for current PFAS testing requirements. 

 

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 or how to test for PFAS, give us a call or send an email today.

Sampling Notes:

 

  • Sample integrity is of the utmost importance when collecting PFAS samples.

 

  • Please help avoid trace or cross contamination of PFAS by adhering to the guidelines set forth by your state environmental services department, and the instructions provided by your lab.

 

  • Never use "Blue Ice" / gel refrigerants / cold packs to chill PFAS samples. Always chill PFAS samples with real ice.

 


Please note: 
ARA is a New Hampshire-based lab, and we are not certified to accept drinking water samples outside of New England. ARA is certified in MA, ME, NH, RI, & VT

 

Not everyone needs to test for PFAS. Follow your state or town water testing guidelines. If you are near a contaminated site, or have a specific concern, you can and should request additional testing.

 

The EPA encourages everyone with a private well to test their drinking water regularly, 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 contact ARA with questions.
