Potential In-Situ Chemical Treatment Strategy for Remediation of PFAS Compounds: Destruction of Emerging Contaminants – PFOS/PFOA

The sources, fate, transport, and remediation of perfluorinated and polyfluorinated alkyl substances (PFAS) are of considerable interest today. This broad group of compounds is proving to be present in groundwater at a wide range of sites, often comingled with other contaminants such as chlorinated solvents and petroleum hydrocarbons. One characteristic uniting these compounds is carbon to fluorine (C-F) bonds, which are among the strongest bonds in organic chemistry. This makes PFAS compounds useful for a wide range of applications, but also makes them very difficult to remediate.

The susceptibility of PFAS  compounds to in-situPicture Edited PFAS Article Potential In Situ Chemical Treatment Strategy for Remediation of PFAS Compounds: Destruction of Emerging Contaminants   PFOS/PFOA chemical remediation, by either oxidative or reductive approaches, is an area of active research. Some groups of PFAS compounds are readily susceptible to chemical oxidation utilizing methods that generate hydroxyl and/or sulfate radicals. However, oxidative treatment is commonly incomplete and more recalcitrant PFAS compounds, such as perfluorooctanoic acid (PFOA), are reported as reaction products that are not further degraded (e.g., Houtz and Sedlak, 2012; McKenzie et al., 2015; Santos et al., 2016). However, other researchers report degradation of PFAS compounds including PFOA under oxidizing conditions (e.g., Liu et al., 2012; Park et al., 2016), via reactions that sequentially eliminate CF2  groups and produce shorter-chained intermediate and final products. This pattern suggests that nucleophilic attack by reactive species other than hydroxyl or sulfate radicals is responsible. Mitchell et al. (2014) report PFOA is mineralized in catalyzed hydrogen peroxide reactions that primarily produce superoxide radicals and hydroperoxide, rather than hydroxyl or sulfate radicals. Superoxide and hydroperoxide are reactive oxygen species that can be formed in some oxidative treatment systems; they are strong nucleophiles and can attack a wide range of compounds that are not susceptible to oxidative degradation by hydroxyl or sulfate radicals.

Geo-Cleanse has developed and patented (U.S. Patent 8,556,537) an in-situ chemical remediation approach that effectively generates superoxide radicals. This method was initially developed to target compounds such as chloromethanes (e.g., carbon tetrachloride) and certain fluorinated compounds (e.g., Freon 113) that are not reactive towards hydroxyl radicals but are readily destroyed by superoxide. We have now completed research to extend application of our method to PFAS compounds. Our method utilizes reaction of hydrogen peroxide with manganese dioxide under neutral to slightly basic conditions to effectively produce superoxide radicals. Laboratory tests confirm that this approach effectively destroys PFOA, without measurable formation of shorter-chained PFAS compounds (Figure 1); indeed, some shorter-chained PFAS compounds (such as PFHpA) that are present at trace concentrations in reagent blanks are also destroyed (Figure 1).Figure 1. PFOA Degradation with Hydrogen Peroxide 1024x637 Potential In Situ Chemical Treatment Strategy for Remediation of PFAS Compounds: Destruction of Emerging Contaminants   PFOS/PFOA

Additional research is needed to further optimize our approach and improve PFAS degradation. We have had considerable success with this approach at DNAPL sites impacted with a wide range of comingled compounds, and thus our approach may also be applicable at typical fire training or other sites in which PFAS compounds are comingled with a range of other contaminants, without concern that incomplete degradation will transform PFAS compounds into more mobile or toxic intermediates.

Geo-Cleanse Sponsored and Presented for Remediation Workshops Across the U.S.

Remediation Workshop 2015 Logo Geo Cleanse Sponsored and Presented for Remediation Workshops Across the U.S.

Geo-Cleanse Sponsored and Presented for 2015 Remediation Workshops!

Presentation: Overcoming Site-Specific Challenges with Innovative In-Situ Remediation

Will Moody, Dr. Dan Bryant, and Stephanie Turkot from Geo-Cleanse International, Inc. (Geo-Cleanse) presented at several locations across the United States this past year for the Remediation Workshops. The Remediation Workshops are a series of half-day technical presentations, which provide information regarding the latest soil and groundwater technologies. The presentations provide an overview of the recent advances in environmental remediation, investigation and laboratory analysis for contaminated sites. Not only do these workshops provide technical information, but they are free to attend, and provide networking opportunities and continuing educational credits.

Geo-Cleanse presented on the technology of in-situ chemical remediation, focusing on the following reagents: permanganate, persulfate, hydrogen peroxide and zero valent iron. The presentation provided an overview of each reagent diving into the chemistry, the strengths and weaknesses, and potential applications. Two case studies were provided to demonstrate the effectiveness of this technology and how combining remedies can be more effective for site cleanup.

The first case study discussed a former Brownfield property in Hartford, CT, which was impacted with volatile organic compounds, semi-volatile organic compounds, and extractable total petroleum hydrocarbons, including a light non-aqueous phase liquid (LNAPL). The treatment program for this site consisted of in-situ chemical oxidation (ISCO) utilizing catalyzed hydrogen peroxide and enhanced product recovery to address the vadose and saturated zone impacts. The second case study outlined a former manufacturing facility located in Greenville, SC, which was impacted with high trichloroethene (TCE) concentrations. The site posed significant remediation challenges, including site access (source area on top of a steep hill, plume extending into a wooded area), deep depths (up to 84 ft below grade), hydrology (low permeability saprolite overlying fractured and highly transmissive bedrock), contaminant concentrations (source area TCE concentration as high as 576 mg/L), and a large plume area (over 16 acres). The plan developed to address the site included slurry emplacement of potassium permanganate for ISCO remediation of the source area, coupled with ZVI for in-situ chemical reduction in the plume area.

Geo-Cleanse strives to provide our clients with well-designed, innovative remedial solutions, and we continue to expand our services to incorporate the advances occurring within the industry.
