Let's Heat Things Up

Thermal treatment approaches offer effective remediation solutions for a wide range of contaminants. By harnessing the power of heat, these methods efficiently remove contaminants from the desired media, mitigating environmental risks and long-term liabilities. Different techniques utilize varying temperatures and implementation designs for a wide range of conditions, ensuring comprehensive remediation. Thermal approaches not only effectively remove contaminants but also promote environmental sustainability by quickly and aggressively eliminating the contamination sources or reservoirs, which eliminate long-term risks to ecosystems and public health.

ABC Cleaners

The Environmental Protection Agency contracted EA to design, construction and operate an in situ thermal remediation/thermal conductive heating system with multi-phase extraction wells and vacuum extraction wells to remediation CVOC DNAPL and soil primarily contaminated with tetrachloroethene at a former dry-cleaning business.

Ex-Situ Treatment Pilot Study

EA is completing research and development programs for SERDP and ESTCP to evaluate ex situ thermal oxidation and thermal desorption of PFAS contaminated materials. A proof-of-concept, pilot-scale study yielded optimized design parameters for full scare treatment. Learn more below.

Nike Missile Battery and Disaster Village Training Area

EA conducted a pre-remedial investigation to refine the understanding of DNAPL contamination extent at a fractured bedrock site in order to update the planned in situ thermal remediation. Delineation, using 3-D modeling and fracture orientation analyses, was performed to optimize the thermal treatment for source area for while also considering power limitations to the site and considering synergistic effects with the downgradient groundwater plume treatment.

Research and Development

For more than a decade, our team has been actively engaged in rigorous applied scientific research related to the environmental fate, toxicity, and treatment of contaminants and contaminants of emerging concern. EA’s in-house subject matter expert working group includes specialists in toxicology, remediation, chemistry, quality systems, engineering design, forensics, and regulatory policy. Recent work includes research programs and studies related to thermal treatment of PFAS.
