Polyfluoroalkyl substances (PFAS), a group of chemicals used since the 1940s, have recently emerged as a contaminant of concern in surface water groundwater due to their persistence and potential to cause adverse human health effects. As a result of this new awareness, the EPA has released draft groundwater clean-up guidelines for public comment. As part of HydroSolutions’ mission to provide our clients with the highest level of technical expertise, our remediation experts will be following these developments in PFAS groundwater remediation standards closely.
