PFAS and “Total PFAS Solution”

Clean Harbors has publicly emphasized its work on per- and poly-fluorinated alkyl substances (PFAS), sometimes referred to as “forever chemicals.” The company reports that it has developed a Total PFAS Solution, which it describes as addressing all phases of PFAS management from analysis to water filtration to remediation to disposal.

The company has disclosed that it operates commercial high-temperature, RCRA-permitted hazardous waste incineration facilities that can destroy multiple forms of PFAS.

Clean Harbors also notes that U.S. EPA and Department of Defense personnel were involved in aspects of this testing.

Beyond incineration, Clean Harbors has highlighted its role in PFAS-related water treatment projects. For example, the company has described contracts for PFAS water filtration work at Joint Base Pearl Harbor-Hickam in Hawaii, where it uses regenerative carbon filtration and resin units to treat groundwater and provide potable water that is safe from PFAS.
