Geotechnical Services by Columbia Basin Analytical Laboratory 

Soil is Our Business.

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 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.

Quality Control and Quality Assurance Credentials

CBAL and RJ Lee Group are partners for your quality control testing processes. We help to improve product process and QC, help ensure compliance, reduce costs, and reduce non-compliance risk. We provide solutions and corrective action plans and verification based on scientific data. How does this apply to our Geotechnical services we offer?


All testing is conducted in accordance with the latest specifications of the American Society for Testing Materials (ASTM), U.S. Army Corps of Engineers, and other pertinent entities.


We follow strict training protocols to ensure analysts understand each method prior to independently analyzing samples; Analysts routinely perform proficiency tests to confirm analytical precision.

Our network of technical experts provides you with customized solutions that are flexible, scalable, and best-suited to your application. For more than 30 years, we have worked toward one goal: to solve the technical challenges you face every day.
How does CBAL work with RJ Lee Group?

Columbia Basin Analytical Laboratories is a joint venture between Columbia Basin College (CBC) and RJ Lee Group, Inc. The partnership, begun in 2001, drove construction of Center for Laboratory Sciences (CLS), a 15,000-square foot facility completed in 2005. In 2014, CLS changed its name to Columbia Basin Analytical Laboratories (CBAL) to emphasize the connection between the college, the laboratory, and its location.

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.
