Started in September 2000 as a licensee of the electrical resistance heating (ERH) technology developed at Pacific Northwest Laboratories, TRS has grown to more than 70 employee-owners in the U.S. with joint ventures and partnerships in South America, Europe and Asia. TRS now provides in situ and ex situ heating solutions using ERH, thermal conduction heating, and steam enhanced extraction. We also provide AFFF clean out services using the PerfluorAd® system.

TRS is a 100% employee-owned company (ESOP), which has fostered a collaborative and cooperative culture and has led to more than 80% repeat business.


The safety of our people and all those who encounter our projects is our primary responsibility. We have developed a comprehensive Behavior Based Safety program that is compliant with OSHA 29 CFR 1910.120. The program reinforces our goal to “Work Safer Every Day” in all facets of our operations. TRS ensures that our subcontractors share the same focus, using extensive subcontractor safety screening, followed by continual training and monitoring of field activities.
