Developing solutions for expanded PFAS identification and testing.


Developing solutions for expanded PFAS identification and testing.

Per- and Polyfluorinated Alkyl Substances (PFAS) are a class of synthetic organic compounds with excellent resistance to thermal and chemical degradation. All PFAS share a similar chemical structure: a neutral per or polyfluorinated carbon chain and an anion organic functional group 'head' to which the surfactant properties of the molecule are attributed. The number of unique PFAS compounds is estimated to be between 5,000 and 10,000.


The landscape of PFAS regulation is growing and changing as new data on the effects of PFAS on human health is reported and as new compounds are introduced to the market by manufacturers. At Metiri, we embrace the challenge of a growing target analyte list and lower reporting limits. We're here to help you with all your PFAS needs. From certifying water PFAS free for equipment and field blanks to our state-of-the-art liquid chromatograph triple quadrupole mass spectrometer, we have all the tools necessary for your project.

The PFAS Challenge

There are multiple challenges with regard to PFAS. The lists, limits, and methods for PFAS keep changing. Since PFAS is difficult to clean up, there is an increasing amount of contamination on sites.


Metiri Group endeavors to be one of the first labs to incorporate a new list or a new limit to stay ahead of the curve. With an established rigorous training program, the Metiri group ensures that personnel are aware of the high expectations they have for quality.

Metiri Group has employed several test methods and offers the newest analytical techniques and methods including:

EPA drinking water method 537.1, 533 and UCMR5 approved

EPA Draft Method 1633

(DoD accredited)

ASTM D7979, ASTM D7968-17a,
ASTM D7968, 537.1M,
and DoD QSM 5.4 Table B15

UCMR5 Approval

The Metiri Group is approved for
UCMR5 by the US EPA.

EPA Draft Method 1633 Accreditation

The Metiri Group achieves DOD Accreditation
for PFAS testing.
DOD 1633 Accrediation

Metiri Group is ready to meet the PFAS challenge

water laboratory testing

Having multiple instruments across several states allows the Metiri Group to have a finger on the pulse with regard to state and federal regulations on PFAS. Metiri strives to be the leader in new PFAS technology.
