ITRC PFAS Beyond the Basics: Topics on PFAS Biosolids: Sources, Transport, and Management of PFAS Surface Releases Training

This training class builds on the earlier information for introductory PFAS topics presented in the PFAS 101 CLU-IN training. The ITRC PFAS Beyond the Basics class provides more information related to potential sources of PFAS in biosolids, implications of PFAS associated with land-applied biosolids, vadose zone fate and transport processes that likely govern biosolids releases, treatment/disposal options for PFAS-impacted biosolids, and regulatory considerations.

Resources and further details for the topics included in this training are in the published PFAS-1 guidance document in Sections 2, 4, 5, 8, 10, 12, and 17.3, and the Regulatory Programs Table.
Learning Objectives:

• Biosolids and PFAS Fate and Transport in the Vadose Zone
• Source Zone Characteristics
• Vadose Zone Controls on Mobility
• Field Scale Fate, Transport and Uptake
• Characterization and Treatment
• Additional Biosolids Considerations and Summary

Sarah LaRoe, Ph.D., Anchor QEA (slaroe@anchorqea.com)
Sarah LaRoe, Ph.D., is a Managing Environmental Scientist at Anchor QEA, LLC in Saratoga Springs, NY. She specializes in chemical fate and transport in contaminated systems, remedial dredge design, and the evaluation of remedial outcomes. She has worked on multiple Superfund cleanup projects, including the Hudson River Dredging Project, the Grasse River Superfund site, and developed CSMs for many PFAS sites. She has been a contributing member of the ITRC PFAS Team since its inception in 2017, focusing on the development of material on the physical and chemical properties of PFAS. Dr. LaRoe received her doctorate from Rensselaer Polytechnic Institute in Environmental Engineering, focusing on microbial bioremediation of recalcitrant contaminants.

Mitch Olson, Ph.D., PE, Trihydro (MOlson@trihydro.com)
Dr. Olson serves as Trihydro's Emerging Contaminants Director and has 23 years of professional experience in consulting and academia. His role involves providing technical guidance on PFAS projects, coordinating PFAS training events within and outside of Trihydro, delivering technical presentations and webinars, and participating in professional organizations (including ITRC's PFAS team). He also provides technical input on projects involving groundwater and soils impacted with hydrocarbons and chlorinated solvents, including monitored natural attenuation (MNA), natural source zone depletion (NSZD), and active remediation systems. Mitch has a B.S. degree in chemical engineering from the University of Minnesota Duluth and received his M.S. and Ph.D. degrees in environmental engineering from Colorado State University (CSU). Dr. Olson maintains Affiliate Faculty status at CSU and is registered as a Professional Engineer in multiple states.

Harrison Roakes, PE, Sanborn Head & Assoc. (hroakes@sanbornhead.com)
Harrison is an environmental engineer and senior project manager with Sanborn Head. He has broad experience in soil and groundwater investigations, and he presents and publishes regularly on statistical analysis of environmental data and subsurface contaminant transport and fate. He is experienced with PFAS investigations and has been involved with PFAS characterization and data analysis at over 25 PFAS-impacted sites, including state-wide background soil studies in Vermont and Maine and multiple projects evaluating PFAS leaching from soil. He holds a B.S. and M.S. in Environmental Engineering from the University of New Hampshire, and he is a registered Professional Engineer in several states.

Angus McGrath, Stantec (Angus.McGrath@stantec.com)
Angus McGrath serves as Stantec's US Environmental Services Technical Lead for PFAS and has more than 25 years of experience working in environmental geochemistry focusing on fate and transport and in situ remediation. Angus has a bachelor's degree in chemistry from Hamilton College, a PhD in Soil Science (Chemistry) from UC Berkeley and served as a postdoctoral fellow at Lawrence Berkeley National Laboratory. Angus currently serves on the ITRC PFAS Team in the fate and transport subgroup and work with clients in various industries (oil and gas, airports, landfill leachate, metal recycling, metal finishing, electronics manufacturing, etc.) on PFAS, metals and solvent related projects.
