Christopher Alger, PG CHG, CEG, joins Terraphase as Principal Engineering Geologist and brings over 35 years of scientific investigation, design and consulting experience in a multidisciplinary problem-solving practice that spans contaminant hydrogeology and site remediation to geotechnical engineering for landslide and slope failure studies.

In his subsurface site characterization and remediation practice, Chris has developed creative solutions to accelerate remediation, regulatory closure and redevelopment of impaired properties in California and throughout the United States.

Chris has designed and implemented a wide range of remediation technologies, including: soil vapor extraction systems for volatile chemicals, in situ fixation injection for hexavalent chromium, in situ and ex situ bioremediation, air sparging, ozone injection, groundwater extraction and treatment, dewatering systems, and excavation programs.

Chris is routinely engaged to provide expert review and opinions in peer review and litigation projects for insurance and attorney clients involved with multi-party disputes nationwide. Chris continues to provide expert services for dry cleaner litigation and resolution, superfund defense, RCRA facility operations and closure, cost recovery, and CERCLA claims. His work in this capacity has included preparing declarations, expert reports, remedial cost estimates, depositions, and other expert witness services.

Chris’s geotechnical engineering work has involved mapping of Landslides and rockfalls in the San Francisco Bay Area, Yosemite National Park, and Utah’s Wasatch Range. He has served as the engineering geologist responsible for pre-construction geotechnical investigations, oversight of client and third-party residential and commercial grading projects, and geologic hazard investigations.
