Profiling Dillon’s leadership in the assessment and management of per- and polyfluoroalkyl substances (PFASs), Andrew Thalheimer spent the week of September 19 presenting in Vancouver and Montreal to provincial regulators and North American airport environmental managers.
Andrew was asked by the BC Ministry of Environment to present "Managing AFFF and Associated PFAS Contamination in the Subsurface" at the 2016 Site Remediation in BC Conference (September 20-21, 2016). The presentation discussed best practices for assessing and addressing legacy environmental impacts associated with per- and polyfluoroalkyl substances in an evolving regulatory climate including key factors that complicate PFAS fate and transport in the environment, such as co-contaminants associated with the application or release of AFFF to the environment.
At the Airport Council International - North America’s Environmental Affairs Committee Workshop held in Montreal (September 24-25, 2016), Andrew provided an update on the research Dillon has been doing for the National Academy of Sciences Airport Cooperative Research Program. The presentation, titled “Update, ACRP 02-60: Use and Potential Impacts of AFFF Containing PFASs at Airports”, summarized preliminary research outcomes including best management practices for managing AFFF (aqueous film forming foam), best practices for addressing legacy impacts in the environment, and AFFF alternatives. In addition, the presentation presented a broad overview of the screening tool that Dillon developed as part of the research program that allows airports to identify and prioritize areas of potential environmental concern at their airports with respect to AFFF and PFASs.
