The Michigan Department of Environment, Great Lakes, and Energy (EGLE), in partnership with the American Institute of Professional Geologists (AIPG), and the Michigan Association of Environmental Professionals, is excited to launch the new Remediation and Risk Management Series. This webinar series is dedicated to helping environmental professionals stay informed about issues and trends that affect remediation and risk management efforts. Each month, EGLE will host a one-hour webinar that will tackle a topic of interest to environmental professionals and others interested in environmental remediation and risk management. Each webinar will include a presentation by a diverse selection of environmental professionals and allow time for questions from attendees.
More webinars will be added throughout the year.
Each webinar qualifies for 1 CEH/PDH.
Upcoming webinars in this series:
April 29, 2021, 12:00 - 1:00PM EST
In September 2020, the EGLE replaced the rescinded Appendix D.1 of the 2013 Guidance Document for the Vapor Intrusion Pathway - Volatilization to Indoor Air Pathway (VIAP) Screening Levels with Residential and Nonresidential VIAP Screening Level Tables. The VIAP screening levels are provided as a voluntary tool that may be used to determine that site conditions do not present a risk and allow a quick regulatory closure or that site conditions warrant a more site-specific evaluation, at common residential and nonresidential sites. This webinar will cover the purpose behind the VIAP screening levels, the basic exposure assumptions used in their development, what documentation is needed for their voluntary use, and their use.
Presenters: Shane Morrison, PhD; Erica Bays; and Melissa Yuvan, EGLE Remediation and Redevelopment Division
May 27, 2021, 12:00 - 1:00PM EST
Join us to find out the latest news on the many PFAS investigations and research being done in Michigan for this emerging contaminant. Since the creation of the Michigan PFAS Action Response Team (MPART) in 2017, Michigan has collected and analyzed samples from 160+ PFAS sites, all of the municipal drinking water supplies in the state, biosolids, municipal waste water, landfills, crops, surface water, and fish and wildlife.
Attendees should expect to hear about MPART's collaborative efforts to address PFAS using a multi-agency team to investigate and work towards solutions. This collaborative effort has not only focused the work of 7 different departments but has also created opportunities for collaboration with citizen groups, industry, and other governmental agencies outside of Michigan. The new MPART Executive Director will discuss the teams efforts on a variety of topics.
Presenter: Abigail Hendershott, Executive Director, Michigan PFAS Action Response Team - Abigail (Abby) Hendershott is a nearly 30-year veteran of the Michigan Department of Environment, Great Lakes, and Energy (EGLE). She currently heads up the state's multi-agency taskforce investigating PFAS contamination and implementing clean-up and other response activities aimed at protecting Michigander's drinking water. Hendershott has focused on PFAS response activities since 2017 and led the team responsible for Michigan's largest PFAS contamination response to-date, the investigation into the former Wolverine Worldwide tannery in Rockford. In that role, her team was responsible for the legal settlement establishing clean-up plans and municipal water connections for thousands of residents in northern Kent County with a total cost of $113 million.
Hendershott also advises on statewide PFAS investigations as the leader of the MPART groundwater workgroup and as a key member of the MPART technical advisory committee. Hendershott was formerly district supervisor for EGLE's Grand Rapids district office where she spent five years heading up the office's remediation and redevelopment division. Hendershott has more than 29 years of project management experience for complex Part 213 and Part 201 state funded remediation projects and has overseen multiple private party cleanup efforts.
Hendershott also has extensive experience in vapor intrusion, serving as team leader for the proposed Part 201 cleanup criteria rules, team leader for the vapor intrusion technical and program support team, and as the primary contact for vapor intrusion investigations handled by the Grand Rapids district office.

Contracting for Remediation Projects: The Michigan Experience (recorded 3/25/2021, 61 min)
Please join us for a webinar exploring state of Michigan contracts utilized for environmental remediation projects. This one-hour webinar will explore the history of state contracts for professional services; the indefinite-scope, indefinite-delivery (ISID) contracts; the ISID solicitation and selection processes; and case studies. Participants can expect to learn a brief history of contracting for professionals services at the state of Michigan; an overview of contracts currently used for environmental investigation, study, design, construction oversight, underground storage tank removal, and laboratory professional services; and case studies focused on contracting. Additional information will include a brief overview of the SIGMA Vendor Self Service (VSS) website.

PFAS Hot Topics (recorded 2/25/2021, 61 min)
Part 1: PFAS Sampling: Results of a Cross-Contamination Study
Can per- and polyfluoroalkyl substances (PFAS) be transferred from common products used during sampling? There is the potential for PFAS to be present in many products that are routinely used in the environmental field. This presentation will show the results of a study performed investigating the potential for cross-contamination from a number of commonly used products. Knowing the types of PFAS that may leach off of a particular sampling material may also be helpful in the forensic evaluation of sample data. Analytical results will be presented along with experimental observations and recommendations.
Part 2: Effects of Variable Analytical Parameter Suites on the Identification of PFAS Sources
Evaluation of the relative composition of individual PFAS compounds in surface water and groundwater samples can be an effective method to identify the source(s) of PFAS in these media. The list of PFAS compounds that laboratories are able to detect and the list of analytes required by various regulatory agencies continues to expand. As a result, the number of compounds that can be used to "fingerprint" samples is variable with time and with location. Attendees will learn about the efficacy and limitations of using PFAS analytes as fingerprints for source identification and delineation.
Presenter: Elizabeth Denly serves as TRC's PFAS Group Program Director and is also the Quality Assurance & Chemistry Director responsible for development of quality assurance project plans, evaluation of PFAS analytical data, and creation of PFAS-specific SOPs for field sampling.
Conceptual Site Models 101 (recorded 1/27/2021, 60 min)
Conceptual site models (CSMs) are a written or pictorial representation of an environmental system and the biological, physical, and chemical processes that determine the transport of contaminants from sources through the environmental media to environmental receptors within the system. Learn what this means from a regulator's perspective and how CSMs play a role in the review of compliance submittals. The webinar will review CSM basics, as well as information and tools that may be available for CSM construction. Every contaminated site has a story to tell, so know your audience and write a great script.
