Environmental Clean-Up + Management

Established in 1943, the Hanford reactors contributed to America’s defense program by producing plutonium for over four decades. The significant volumes of hazardous waste, a by-product of plutonium production, remain the focus of environmental cleanup for the past 30 years.

From 2018-2023, our involvement with the U.S. Department of Energy (DOE) and Washington River Protection Solutions (WRPS) in a Mentor-Protégé partnership marked our commitment to hazardous waste cleanup around Hanford.

Now equipped with the expertise, our organization has evolved into a formidable general contractor in Environmental Management (EM), offering cost-effective solutions for nuclear, defense, energy, and hazardous waste industries. We provide comprehensive construction support and services for federal, state, and local government entities.

We are dedicated to elevating the client experience.
