Cradle to Grave

We provide total waste management services for commercial and government agencies throughout the entire waste life-cycle. We have been managing and treating waste for disposal since 1991, and with our network of three fully licensed and permitted radioactive and hazardous waste processing facilities, we are well versed in all phases of waste management. We plan treatment campaigns based on the designated disposal cell waste acceptance criteria and land disposal requirements, and based on our vast experience of managing wastes destined for all major federal and commercial radioactive disposal cells in the U.S. and Canada.

Complex Waste Problems

We have a long standing reputation for developing unique treatment capabilities for the most difficult and complex waste streams. Years of treatment experience coupled with sound engineering practices, intimate knowledge of RCRA & TSCA regulations, and on-site fabrication expertise has allowed us great success in treating a myriad of previously orphaned waste streams.



Innovative Rapid Survey Technologies

As one of the largest turnkey radiological support services contractors in the U.S., we offer advanced technologies supporting radiological and hazardous facilities for site characterization, innovative rapid survey technologies, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) compliance, and Final Status Surveys (FSS).


A Comprehensive and Turnkey Solution

Clients rely on our industry experts for their ability to manage complex projects dealing with hazardous and radiological contaminants while ensuring regulatory and safety compliance.


Broad Experience Across Markets

Our project experience covers the full spectrum of radiological hazard environments from nuclear reactor containment vessels to radiologically contaminated structures and surrounding environments. We have experience performing these services under a wide variety of conditions, such as in ecologically sensitive areas, unstable structures in close proximity to historically significant structures, highly congested areas, and within occupied buildings.
