XDD’s Vice President Dennis Keane authored an article titled “PFAS Remediation: Where Are We Now?” published in Energy Empowered by the Midwest Energy Association (MEA).
The article elaborates on the following topics:
- How the timeline for PFAS remedial technology development compares to petroleum compounds and chlorinated solvents.
- The source of PFAS that are common to many environmental sites in the energy sector.
- PFAS regulatory background in the United States.
- Difficulties associated with environmental sampling. As a note, while state regulations often disallow the use of certain materials/products when sampling for PFAS, many manufacturers have developed products that are now free of PFAS.
- A review of PFAS in environmental media thought to represent background conditions.
- Remedial technologies:
- Adsorption and Ion Exchange
- Filtration and Osmosis
- Bioremediation
- Chemical Oxidation
- Thermal
- The future of remedial approaches for PFAS
