Clinical Laboratory of San Bernardino, Inc. located at 21881 Barton Road in Grand Terrace, California, has been providing quality analytical services to State and Federal agencies, cities and water districts throughout Southern California since 1968.

 
The laboratory began as a medical lab and soon expanded into the area of water testing.  The medical end of the business was dropped many years ago and the laboratory continued with a specialty of drinking and wastewater analyses.  With our affiliate laboratory in Lompoc, CA and Hesperia, CA, we have successfully extended our service area into the Central, Coastal, High and Low Desert regions of California.

Clinical Laboratory of San Bernardino's Project Management Team provides our valued clients with personalized, efficient, and courteous service that sets us apart from other laboratories.

The State Water Resources Control Board has certified the Hesperia and Lompoc locations for complete bacteriological testing. In addition, the Grand Terrace laboratory is certified for Microbiology, Organic, Inorganic, and Radiological constituents
