S.E.T.'s ENVIRONMENTAL DIVISION

S.E.T.'s Environmental Division provides specialized environmental science and engineering services (from site investigation to final closure) for private industry clients. Our solution-oriented approach to environmental issues is committed to provide a personal client-consultant partnership, ensuring client satisfaction and cost-effective project completion without sacrificing quality.

S.E.T. also holds a Radioactive Broker/Consultant License from the Colorado Department of Public Health and Environment (CDPHE), which enables S.E.T. to work in radioactive environments throughout the USA and abroad.
