Treatment technologies are needed to address per- and polyfluoroalkyl substances (PFAS) in soil and groundwater. Significant investments have been made and are planned to develop and improve technologies for PFAS remediation, drinking water treatment, and waste management. In this environment of research and development, lines of evidence and best practices to assess the effectiveness of PFAS treatment technologies were developed.
In collaboration with PFAS researchers and practitioners, the project team developed lines of evidence, best practices, and other considerations for assessing PFAS treatment technology performance. The project was organized into three tasks:
The results of the three tasks are summarized in the guidance document that describes each line of evidence, best practices, and other considerations, provides a myriad of examples from relevant peer-reviewed literature, and provides checklists to guide assessments of PFAS treatment technologies.
This project developed clearer guidance, metrics, and checklists for researchers and practitioners to evaluate the fundamental success of PFAS treatment technologies at various stages of technology development. Project results may be relevant to other chemicals of concern beyond PFAS. (Project Completion - 2021)
