Pace Offers PFAS Test Method for Contamination Detection

Pace Analytical Services, a provider of regulatory testing and analytical laboratory services, has made the PFAS Test Method ASTM D8421/EPA 8327 available to the public. The test method applies to aqueous and solid sample material.

ASTM D8421/EPA 8327 uses isotope dilution and liquid chromatography tandem mass spectrometry (LC/MS/MS) to analyze for as many as 44 PFAS compounds in both aqueous and solid sample material. The test method offers a number of advantages over other PFAS test methods, Pace says. The test requires only a 5 mL sample, helping to reduce waste, and the results can be delivered faster and at a lower price. The result of isotope dilution calibration and quantification is greater reliability of results. In addition, the method offers method detection limits (MDLs) that meet the EPA’s proposed drinking water standards and regional screening levels (RSLs).

“With the increasing focus on PFAS contamination of our environment, Pace is seeing greater demand than ever for reliable, fast testing services for complex matrices, including soil, ground and surface water, landfill leachate and more,” says Paul Jackson, Pace program manager, environmental compliance and emerging contaminants. “We are excited to be able to offer customers the ability to get results faster for important decision-making and/or to comply with increasing regulatory requirements.”

Pace is able to cite method ASTM D8421 or EPA 8327 because of the similarities of the methods. The company combined the two into the same service offering and, therefore, can cite either method depending on a customer’s regulatory jurisdiction and data quality objectives.
