Geotechnical Services by Columbia Basin Analytical Laboratory
Soil is our business at RJ Lee Group’s Columbia Basin Analytical Laboratory (CBAL) Geotechnical department. The CBAL Geotechnical Department started in 2015 to provide quality testing in support of the US Department of Energy’s Hanford Site. We specialize in measuring the physical properties of soil for the geotechnical, environmental, construction and mining industries. We strive to deliver the most accurate testing results to clients in a timely manner. CBAL’s Quality Management System and Soil Testing is accredited by AASHTO (formerly AMRL), A2LA, USACE, and the U.S. Department of Energy/Defense (DOECAP).
CBAL also holds a Radiological Materials License from Washington State, a United States Nuclear Regulatory Commission (NRC) agreement state. This license allows us to receive, analyze, and dispose of samples containing low-level radiological contamination.
Geotechnical Testing Services and Capabilities
Soil Classification and Index Property Tests
- Water Content Determination (D2216)
- Density Determination (D2937)
- Atterberg Limits (D4318)
- Particle Size Distribution (D422)
- Specific Gravity of Soil Solids (D854)
- Proctor Compaction (D698/D1557)
Soil Corrosivity Testing

We recently acquired USACE Validation as well as certification for our technicians by the American Concrete Institute (ACI) for Aggregate/Soils Base Testing. This is in addition to our existing DOE and AASHTO accreditations. We are also approved by Washington state (an NRC/EPA agreement state) to handle environmentally and radiologically contaminated/hazardous soils at our laboratory facilities.

How does CBAL work with RJ Lee Group?
The goal of the joint venture was to create one of the first public-private partnerships in the state of Washington that would focus on science, technology, engineering, and mathematics (STEM) education, while providing students with commercial laboratory skills. Today, the laboratory is used as a resource for demonstrating day-to-day laboratory techniques and procedures, as well as to promote the conception and execution of unique research projects.
