PFAS Testing at Energy Laboratories, Inc.

Energy Laboratories is accredited to test for PFOA, PFOS, and several PFAS replacement compounds in drinking water by EPA Method 537.1. Energy Laboratories is also accredited through the Department of Defense (DoD) to perform PFAS testing on other environmental matrices such as groundwater and soil using an isotope dilution method, which is widely considered the gold standard for PFAS analysis.

What are PFAS?
Per- and polyfluoroalkyl substances (PFAS) which are a group of man-made chemicals used in a wide variety of consumer products and industrial applications. There are thousands of different PFAS compounds in existence which may be found in clothing, non-stick cookware, fire-fighting foams, adhesives, and food packaging. PFAS have the potential to build-up in the environment over time because they are resistant to degredation. Exposure occurs primarily from eating food or drinking water contaminated with PFAS.

In 2016, the US EPA established a lifetime health advisory of 70 parts per trillion for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) in drinking water. Even though PFOA and PFOS are no longer manufactured in the US, various imported consumer products may still contain these chemicals. Newer PFAS compounds such as GenX have replaced PFOA and PFOS in some manufacturing and consumer products.

Energy Laboratories utilizes state-of-the-art instrumentation and equipment dedicated to PFAS analysis. This enables reporting limits as low as 2 parts per trillion in water samples and 1 ng/g in soil samples without compromising accuracy and precision.
