Join us for our next webinar on June 11th at 12:30 EST, focusing on “Destruction Of PFAS Using Catalyzed Chemical Oxidation.”
Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that were widely used in the consumer product stream since the 1950s. Research has established a link between PFAS exposure and a range of adverse health outcomes. The chemicals pose a significant environmental and public health concern due to their persistence, widespread contamination, and potential health effects. PFAS are difficult to address in natural media and tend to be highly recalcitrant in the environment. Our objective is to develop a chemical oxidation process with low-energy activation methods to destroy PFAS in ex situ and in situ settings.
Through laboratory research, Parsons has optimized catalyzed chemical oxidation for destruction of PFAS by combining a small temperature rise, a metal-based catalyst, and off the- shelf oxidant products. This methodology, called Hot In Situ Chemical Oxidation (ISCO), has been demonstrated to destroy perfluorocarboxylic acids and fluorotelomers, while degradation of perfluoroalkyl sulfonates has been observed with research ongoing regarding fluoride mass balance.
Hot ISCO has potential as a PFAS destructive technology using a well-studied oxidant. The use of metals as a catalyst provides a low-energy activation of the oxidant. This combination has potential for ex situ and in situ application. Laboratory and field ex situ demonstrations across a wide variety of groundwater and soil conditions, PFAS mixes, and complex matrices have yielded a tremendous collection of lessons learned and a much deeper understanding of PFAS destruction mechanisms and ideal application conditions.
