PFAS testing looks for a group of manmade chemicals called per-and polyfluoroalkyl substances (PFAS). The Michigan Department of Health and Human Services reports that it is not uncommon to find low levels of PFAS in drinking water supplies, as PFAS can be found in fire-fighting foams, stain repellants, nonstick cookware, waterproof clothing, food wrappers, and many other household products. PFAS compounds do not break down in the environment and they move easily into water.
The EPA has set a Lifetime Health Advisory (LHA) level for two PFAS in drinking water, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS). The LHA level is 70 parts per trillion (ppt, equal to 70 ng/L) for PFOA and PFOS combined, or individually if only one is present. The EPA has not set health advisory levels for other PFAS compounds. The State of Michigan is using 70 ppt for decision making purposes.
Over the past year, we have tested hundreds of drinking water, waste water, soil, leachate, groundwater, foam and surface water samples for PFAS. Our clients include municipalities, county and state agencies, manufacturers, landfills, homeowner associations and home owners across the lower peninsula of Michigan. We pre-screen analytical laboratories specializing in PFAS analysis to help our clients meet their specific certification, method, and quality objectives. For drinking water, several versions of EPA Method 537 are used by laboratories – we only use laboratories that are certified for EPA Method 537 Version 1.1. When combined with our environmental scientists who are trained in specialized sampling methods associated with the collection of representative PFAS samples, you are provided with information to confidently make decisions.
Our engineers and State of Michigan Certified Operators have decades of experience in addressing contamination. As your independent advisor, we provide recommendations from a stable of vendors and technologies that meet your PFAS removal objectives.
