WORKSHOP - PLATFORM PRESENTATION
Considerations for Evaluating PFAS Disposal Options
The subject of PFAS waste disposal has become one of the most discussed topics in the industry with many different opinions about the best solution. The EPA Guidance Document for PFAS Disposal did not make recommendations for particular technologies but suggested areas of where there are gaps in data. In response, recipients of this material are having to make decisions without clear and comprehensive guidance. Until clear guidance from Federal, State and Local Authorities has been finalized PFAS material disposal will be a complicated and nuanced subject where decision makers will have to create a disposal policy narrative. Facilities that receive waste are also making decisions based on their own internal policies and some are choosing to direct this material to specific types of facilities or making the decision to not accept PFAS impacted materials at all. This presentation is not meant to direct the practitioner to one option or the other but rather to discuss the practical considerations such as technology acceptance, levels of regulation, discharge control, viability and scalability. It is also important to identify and define what criteria is ultimately chosen to compare options and make a decision about how to dispose of the PFAS impacted materials.
