Countless Americans have been exposed to PFAS, which refers to manmade poly- and perfluoroalkyl substances, including perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). These global pollutants are dubbed “forever chemicals” as the compounds don’t naturally degrade, posing significant health risks. While PFAS is now emerging as an environmental crisis—spurring several states to regulate as the EPA positions to take action—Apex has been on the forefront of its investigation, assessment, and characterization. For nearly a decade, we’ve been helping our clients accurately measure and understand the extent and severity of their PFAS impacts. Now, we are ready to apply our expertise to help you do the same.
