TerraTherm SVP Jim Galligan Talks Thermal Technologies on the Environmental Transformation Podcast
May 16, 2025
GARDNER, MA – What do you get when you combine 34 years of experience, a global portfolio of complex cleanup projects, and a passion for sustainable remediation? A powerful conversation worth tuning into.
In a recent episode of the Environmental Transformation Podcast, host Sean Grady sits down with Jim Galligan, Senior Vice President at TerraTherm, for an in-depth discussion on the practical and strategic application of in situ thermal remediation (ISTR) technologies.
Jim walks listeners through key approaches like Thermal Conduction Heating (TCH), Electrical Resistance Heating (ERH), and Steam-Enhanced Extraction (SEE)—and explains how these systems are used to tackle recalcitrant contaminants such as PFAS, chlorinated solvents (PCE/TCE), PCBs, dioxins, and petroleum hydrocarbons. Throughout the episode, he demystifies the thermal process, shares insights into lifecycle cost comparisons with chemical oxidation, and highlights how modern thermal solutions overcome challenges related to depth, geology, and infrastructure.
Episode highlights include:
• Why “deeper is cheaper” when it comes to subsurface thermal treatment
• The role of site characterization and utility power planning in thermal system design
• Misconceptions about thermal remediation and how to address them with clients and regulators
• Case studies showcasing real-world success across diverse site types
• An overview of TerraTherm’s mission, future innovations, and PFAS treatment advancements
Whether you're an environmental consultant, remediation engineer, or program manager, this episode offers field-tested guidance for designing and executing effective thermal remedies—especially at complex or high-risk sites.
