Geotechnical Services by Columbia Basin Analytical Laboratory
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 Soils Analysis is part of our core business at our Columbia Basin Analytical Laboratory in Pasco, WA. We strive to deliver the most accurate testing results to clients in a timely manner.
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.

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?
Testing
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.
Training
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.

Jacob Throolin
MANAGER – GEOTECHNICAL SERVICES, WASTE COORDINATOR, RSO
Our Geotechnical Department Manager, Mr. Jacob Throolin, is a Washington State licensed geologist with over 14 years of experience in the engineering, environmental, mining, and petroleum industries. Throughout his career he has consistently provided quality and defensible data to clients.
His experience includes subsurface field explorations, including drilling, rock coring, soil sampling and environmental sampling, characterization and profiling of underlying soils; geologic reconnaissance and site exploration; tunnel air quality monitoring; and tunnel assessment. He has performed and overseen construction observation, including foundation subgrade preparation and soil bearing, subsurface drainage installation, mass soil excavation, fill placement and compaction, pier shaft drilling, soil nail and tieback installation and testing, rock bolt installation, auger cast pile installation, and pile and micropile installation and monitoring.
He has conducted inclinometer data collection and processing, geophone ground vibration data collection and processing, environmental soil and groundwater testing and sampling, well infiltration and replenishment testing, falling head infiltration testing, formation hydraulics packer testing, well and groundwater level instrumentation and data collection.

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.
