Earth Systems laboratories have been accredited, accepted, validated or approved as appropriate for various test methods by the California Department of Transportation (Caltrans),  the Division of the State Architect (DSA), the U.S. Army Corps of Engineers, and the City of Los Angeles Department of Building and Safety, and the Department of Health Care Access and Information (HCAI); please refer to each agency or organization’s website for information pertaining to Earth Systems’ individual laboratory qualifications. Several of our laboratories are assessed by the AASHTO Accreditation Program (AAP), and they participate in proficiency sample programs through AASHTO re:source and the Cement and Concrete Reference Laboratory (CCRL).  These laboratories are evaluated by the AASHTO Accreditation Program (AAP) for compliance with AAP procedures. Please refer to the AASHTO re:source website https://aashtoresource.org for the compliance status of our laboratories in your area. Laboratory equipment is calibrated annually, and the calibrations are traceable to the National Institute of Standards and Technology (NIST).  Our laboratories are under the supervision of licensed professional engineers and laboratory testing is performed by qualified and trained technicians in accordance with ASTM, Caltrans, AASHTO, and other appropriate laboratory methods.
