Brownfield Braintrust Podcast

In this episode of the Brownfield Braintrust podcast, Matt Winefield sits down with Greg McIver of Citadel EHS, one of the few environmental consultants in California who has successfully secured No Further Action letters for VOC-impacted sites in 2024 and 2025. With California closures down more than 50 percent in recent years, this conversation offers rare, practical insight into what still works under the state’s evolving vapor intrusion guidance.Greg walks through two real dry cleaner case studies from San Mateo County and the Central Valley, highlighting the technical approach, remediation steps, stakeholder engagement, cost considerations, and multiple lines of evidence that led to successful closures. Together, Matt and Greg unpack the importance of early regulatory buy in, a complete conceptual site model, strategic use of the Low Threat Closure framework, and how to prioritize work when a property owner has limited resources.If you evaluate, investigate, remediate, or acquire VOC-impacted properties in California, this episode provides a clear, candid look at how closure is still achievable today.
