Perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA) and their related perfluoroalkyl andx000D
polyfluoroalkyl surfactants (PFASs) have been found in many federal and private facilities from the use of andx000D
release of aqueous film-forming foams (AFFFs). Driven by the new regulations on PFOS and PFOA, there is ax000D
great need for developing cost-effective and efficient treatment technologies for removing these persistent andx000D
toxic chemicals from wastewaters. As PFOS and PFOA are highly stable and resistant to microbial or chemicalx000D
attacks, conventional advanced oxidation or sorption-based processes are either not effective or are very costx000D
prohibitive. Golder Associates is planning to offer a novel non-thermal plasma technology to its clients inx000D
future projects for PFAS wastewater treatment. Although non-thermal plasma has been reported as the mostx000D
effective process to break down PFAS completely, few measurement and validation tests have been conductedx000D
to determine pollutant degradation efficiencies and degradation end-products. Therefore, a new collaborativex000D
partnership between Golder and the applicant (Prof. J. Liu) at McGill University, who is an expert onx000D
measurement, treatment and environmental fate evaluation of PFAS, to address the issues. The goal of the newx000D
partnership is to assess the technical and economic feasibility of the technology. This project will also generatex000D
new knowledge on PFAS degradation mechanisms in non-thermal plasma processes. The industrial partner canx000D
use the knowledge to support scale-up of the technology and to expand its client base. The project will benefitx000D
Canada's economy and the environment by reducing the cost of dealing with PFAS contamination.
