TRS Group, A Parsons Company is an environmental services contractor focused on rapid remediation of contaminated sites through in-situ thermal technologies. The firm backs its approach with a 100% money-back guarantee and aims to eliminate environmental liabilities. Its origins trace back to a remediation process developed by the U.S. Department of Energy and Battelle Pacific Northwest National Laboratories in 1997, which led to the formation of Thermal Remediation Services, Inc. in 2000 and later to the current TRS Group, Inc. The company has refined an in-situ electrical resistance heating method via a proprietary engineering model and also provides thermal conduction heating, steam enhanced extraction, and PFAS and AFFF remedial solutions. It now delivers its remediation technologies worldwide through joint ventures in Brazil, Europe, and Great Britain. 

Empirical data from more than 200 operating projects underpins its remediation approach, illustrating experience across sites of varying size. Based in Indianapolis, Indiana, the company serves clients seeking remediation of contaminated sites. In September 2024, Los Angeles World Airports announced a partnership with TRS Group to advance environmental remediation initiatives at LAWA projects.
