Geotechnical Services

Soil is Our Business

In 2015, RJ Lee Group established our Columbia Basin Analytical Laboratory (CBAL) in Pasco, WA to provide geotechnical testing services 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.  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). 

RJ Lee Group also holds a Radiological Materials License from Washington State, a United States Nuclear Regulatory Commission (NRC) agreement state. This license allows our CBAL facility to receive, analyze, and dispose of samples containing low-level radiological contamination.
