Used at fire training and emergency response sites since the 1970s, Per- and Polyfluoroalkyl substance (PFAS) contamination from aqueous film-forming foam (AFFF) presents a multi-million dollar challenge for a myriad of industrial and Department of Defense (DoD) sites across the country. Legacy contamination has persisted in the environment for decades, ultimately migrating from source zones to drinking water supplies of nearby communities. While technology such as ion exchange has shown success in removing PFAS ex-situ, there is still a need for advanced in-situ remediation and characterization techniques.
In response, the DoD is collaborating with academic institutions, private industry, and SERDP-ESTCP to find remediation solutions. Many projects are currently in progress along Colorado’s Front Range with the aim of informing best practices for removing and destroying PFAS contamination from AFFF in soil and groundwater.
Although a drinking water MCL for PFAS has not been implemented in our state, Colorado has promulgated a site-specific groundwater standard and has listed PFOA and PFOS as hazardous constituents. Additionally, the EPA’s PFAS action plan demonstrates that more stringent federal regulation may be expected in the future.
This presentation will provide the most up-to-date overview of the novel remediation technologies currently piloted at both the field and at the bench-scale at Peterson and Schriever Space Force bases.
Rachel Blomberg is a registered professional engineer (P.E.) and serves as a hydrologist and project manager for the Colorado Department of Public Health and Environment (CDPHE) in the Hazardous Materials and Waste Management Division Remediation Program. She has been employed by CDPHE since 2017, and worked for the USGS in their Colorado Water Science Center before joining the State. Rachel’s primary duties range from asbestos mitigation to contaminated groundwater cleanup on active military bases and formerly used defense sites, but she primarily focuses on emerging contaminants through her PFAS response efforts at Colorado’s Air Force Bases and through her involvement in drafting new site-specific groundwater standards.
Rachel earned a BS from Cornell University and a MS from Colorado School of Mines. Originally from Northern California, she has lived in NY, AK, ME, Denmark and finally Colorado. She spends much of her free time renovating her century old home in Denver. When she is not doing that, she is most likely hiking or cross country skiing with her American Bulldog, fishing, cooking a new recipe, or enjoying a local show or game night.
