Vapor Intrusion Today: Industry Experience, Decision Tools, and Regulatory Updates
Vapor Intrusion Today: Industry Experience, Decision Tools, and Regulatory Updates
Thursday, February 5, 1:00 pm – 2:30 pm ET
Contaminant vapor intrusion is an important consideration of environmental risk management, and the V.I. evaluation framework is an evolved and regulated practice. This webinar will provide an overview of the current state of this practice. Presentations will address regulatory updates, site characterization goals and challenges, data interpretation, and risk/mitigation decision-making strategies.
Emphasis will be placed on current practices, practical tools, and common challenges encountered during vapor intrusion investigations and mitigation. Case examples will be used to illustrate practical approaches, decision-making processes, and compliance considerations.This program is intended for environmental professionals, regulators, and stakeholders involved in site assessment, remediation, and risk management.

Paul Ecker, RG, LHG, EES Environmental Consulting Inc.
Paul is a relative newcomer to A&WMA, joining Portland, Oregon’s local chapter in 2017 and becoming a board member the following year. Paul began his environmental consulting career in Portland in 1990 and founded a small firm called EES in 2012 to focus on remedial investigation, cleanup, and environmental technical support services. Paul’s team at EES has a special interest in vapor intrusion assessment and mitigation, and Paul is thrilled to have moved beyond the early days of hand-driven vapor probes.
Robert Ettinger, Senior Principal Environmental Scientist, Geosyntec
Robert Ettinger is a senior principal environmental scientist with Geosyntec based in California with over 35 years of professional experience. He specialized in vapor intrusion investigations, risk-based corrective action assessments, and mitigation system implementation for former and current gasoline retail and distribution, dry cleaning, manufacturing, and petrochemical facilities. Mr. Ettinger’s contributions to advancing the state-of-the-practice began with his co-authorship of the Johnson and Ettinger (1991) algorithm for evaluating the vapor intrusion pathway. Over his career, he has made additional contributions through field investigations and modeling evaluations.
