What TRS Group does
TRS Group, Inc. is a U.S.-based environmental remediation contractor specializing in thermal treatment of contaminated soil, bedrock, and groundwater. The company deploys three core in-situ and ex-situ technologies: FlexHeater Thermal Conduction Heating (TCH) using flexible heaters capable of reaching 600°C for VOCs, SVOCs, and PFAS; OptiFlux Electrical Resistance Heating (ERH) that uses electrodes to heat soil to the boiling point of water for VOC treatment in all soil types and sedimentary bedrock; and Steam Enhanced Extraction (SEE) for LNAPL removal in sand and gravel formations. TRS also operates an ex-situ PFAS Thermal Desorption service that has achieved soil pile temperatures up to 414°C across three completed DOD demonstrations, including the largest project at Joint Base Elmendorf-Richardson in Anchorage, Alaska.
The company has completed more than 200 projects primarily for source zone removal of chlorinated solvents, petroleum hydrocarbons, and PFAS, typically reporting contaminant concentration reductions exceeding 99.9%. TRS holds patents on its FlexHeater TCH and OptiFlux ERH systems and offers performance guarantees on more than 75% of its projects, supported by three consecutive years of Exceptional CPARS ratings. Revenue is generated through project-based contracts — fixed-price, cost-plus federal work, and time-and-materials subcontracts with environmental consulting primes — with no public pricing disclosed.
Primary customers are federal agencies, including the U.S. Air Force, U.S. Army, U.S. Army Corps of Engineers, and U.S. EPA, addressing more than 700 DOD PFAS-impacted sites and federal Superfund properties. TRS also serves as a thermal subcontractor to environmental consulting firms such as Ramboll, HydroGeoLogic, V3 Companies, Wilcox Environmental Engineering, Environmental Restoration, and de maximis. Headquartered in Chantilly, Virginia, TRS operates across North America, South America, and Europe and was acquired by Parsons Corporation (NYSE: PSN) on February 4, 2025, where it now operates as a wholly-owned subsidiary under the brand 'Thermal Remediation Services | TRS Group, A Parsons Company'.

TRS Group product offering
Product offeringCore offering
TRS Group is an environmental services firm specializing in thermal remediation of contaminated soil and groundwater. The company deploys proprietary thermal technologies — including electrical resistance heating (ERH), thermal conduction heating (TCH), and steam-enhanced extraction — to treat sites impacted by chlorinated solvents, petroleum hydrocarbons, and PFAS. Its work is delivered as turnkey remediation projects for federal agencies, environmental engineering firms, and industrial clients.
Product overview
TRS Group, a Parsons company, provides thermal remediation technologies for the volatilization and destruction of organic contaminants (chlorinated solvents, petroleum hydrocarbons, PFAS) from soil, bedrock, and groundwater. The product portfolio consists of three main thermal remediation technologies: FlexHeater® (Thermal Conduction Heating/TCH) for VOCs, SVOCs, and PFAS in all matrices; OptiFlux® (Electrical Resistance Heating/ERH) for VOCs in all matrices; and Steam Enhanced Extraction (SEE) for LNAPL removal in sand and gravel. TRS has completed more than 200 projects and offers performance guarantees on over 75% of projects, typically achieving contaminant concentration reductions exceeding 99%.

Products and services
- FlexHeater Thermal Conduction Heating (TCH) In-situ thermal conduction heating service that raises subsurface temperatures to volatilize and destroy chlorinated solvents, hydrocarbons, and other recalcitrant contaminants in soil and bedrock for federal, state, and industrial site cleanups.
- OptiFlux Electrical Resistance Heating (ERH) In-situ electrical resistance heating service that boils groundwater in place to strip volatile and semi-volatile organic contaminants from saturated soils, targeting chlorinated solvent and hydrocarbon source zones.
- SEE (Steam-Enhanced Extraction) Steam-enhanced extraction service that injects steam into the subsurface to mobilize and recover non-aqueous phase liquids (NAPLs) and dense non-aqueous phase liquids (DNAPLs) from contaminated aquifers.
- PFAS Thermal Desorption Thermal desorption service that destroys per- and polyfluoroalkyl substances (PFAS) in soils through high-temperature treatment, offered to federal, state, and industrial clients managing PFAS-impacted sites.

TRS Group competitors and assessment
Company assessmentDirect peers
- TerraTherm: TerraTherm is a direct competitor providing in-situ and ex-situ thermal remediation services (Thermal Conduction Heating, Electrical Resistance Heating, Steam-Enhanced Extraction) for chlorinated solvents and emerging contaminants — overlapping head-to-head with TRS's core technologies.
- Cascade Environmental: Parent of TerraTherm and a direct thermal remediation services competitor; offers similar in-situ thermal desorption and ERH technologies for federal, industrial, and Superfund projects, making it a closely comparable specialty contractor.
Broad incumbents
- Clean Harbors: Large publicly-traded environmental services firm offering hazardous waste treatment, disposal, and emergency response — a broader incumbent that overlaps with TRS in PFAS-impacted soil handling and federal environmental contracts at a much larger scale.
- Tetra Tech: Global consulting and engineering firm with a substantial environmental remediation practice serving federal agencies (DOD, EPA) and industrial clients — overlapping with TRS in federal PFAS and chlorinated solvent remediation programs, though as part of a much broader portfolio.
- AECOM: Global infrastructure consulting firm with a sizable environmental services practice covering site assessment, remediation, and federal environmental programs — competes with TRS on large DOD/EPA remediation pursuits as both prime and subcontractor.
- Jacobs Solutions: Major engineering and environmental services firm with a federal environmental remediation practice (DOD, EPA), often serving as prime contractor that subcontracts thermal remediation work — overlapping with TRS as both competitor and potential channel partner.
- Arcadis: Global design and consultancy with a dedicated environment and water remediation practice serving industrial and government clients; comparable to TRS in PFAS remediation strategy, though at much larger scale and broader service scope.
- ERM (Environmental Resources Management): Global environmental consulting firm providing site investigation, remediation, and compliance services to industrial and government clients; overlapping with TRS as a remediation project partner and competitor on federal/industrial PFAS programs.
Others
- Ramboll: Global engineering and environmental consulting firm already a documented TRS partner for thermal conductive heating projects; comparable because Ramboll both subcontracts thermal remediation to TRS and competes for adjacent federal remediation programs as a prime contractor.
Regional players
- Sevron Safety Solutions: UK-based environmental and safety consultancy with thermal remediation and in-situ chemical oxidation capabilities for European contaminated sites — comparable technology stack to TRS but primarily serves the UK and European market rather than North America.
