Our geologists have expertise in all types of geologic hazards investigations, including probabilistic and deterministic seismic risk, fault rupture hazard, liquefaction, landsliding, shallow groundwater, rippability, disaster remediation, forensicgeology studies, mining reclamation, and expert witness testimony. We also provide complete groundwater resource exploration and development services such as horizontal and vertical well siting, well design/construction recommendations, and aquifer testing/evaluation.

CHJ Consultants’ geologists have planned, conducted, and reported tens of thousands of feet of trench excavations across major active faults such as the San Andreas, San Jacinto, Elsinore, and Cucamonga faults, as well as across minor faults such as the Murrieta Hot Springs and Lytle Creek faults. We have completed major subsurface investigations of slope stability for hillside developments in such geologically challenging areas as the Chino Hills and the foothills of the San Bernardino Mountains. We have developed a reputation as one of the pre-eminent engineering geology consultants in Southern California.
