Project milestones, patents, and where to hear ERG speak.
The California Department of Toxic Substances Control issued a No Further Action determination for unrestricted land use at Carson Plaza in Carson, California. A phased combined remedy beneath an operating dry cleaner, finished with an eight-well HETR™ wellfield, reduced PCE and TCE about 99% in soil, groundwater and soil vapor.
Read the case studyAt the Fourteenth International Conference on Remediation of Chlorinated and Recalcitrant Compounds, Rob D’Anjou presented ERG’s thermal work, and Rob and Cheyney Zhou presented the poster Low- to Mid-Temperature Thermal Platform for Integrated and Sequential In Situ Remediation: how ThermaCycle® delivers heat, hydraulic control and amendment chemistry through one closed-loop system, from stalled bioremediation sites to DNAPL source zones.
Download the poster (PDF)At the AEHS 35th Annual International Conference on Soil, Water, Energy, and Air, Rob D’Anjou gave the platform presentation In Situ Thermal Remediation Across the Temperature Spectrum: Technology and Implementation Strategies Matched to Site Conditions and Remedial Objectives, covering where each thermal mechanism fits, spatiotemporal integration of combined remedies, and field results from HETR™ and ThermaCycle® projects.
Download the presentation (PDF)The patent, titled Method and apparatus for thermal remediation of contaminant impacted media with hybrid energy systems, covers ERG’s hybrid energy approach to thermal conduction heating.
About HETR™At the Hydrocarbons & Halogens Enviro Workshops, Rob presented Creative Thermal Technologies and Thoughtful Remediation Strategies to Maximize Returns on Remedial Investments: an overview of in situ remediation technologies, combined remediation approaches and implementation strategies across the project life cycle, with case studies.
Project updates and technical notes are posted on ERG’s LinkedIn page and in the ERG blog.
Send us the basics: contaminants, depth, geology and the cleanup goal. A principal will review the site and tell you whether heat fits, which approach, and what a full evaluation involves.
