Expert ID: 730818 California, USA

Request Expert

Expert has applied his geology background to oil spills and gas leaks and assessment and remediation of soil and groundwater resources impacted by petroleum hydrocarbons, solvents, heavy metals, fungus, etc. He is involved with a variety of litigation support projects over the past 22 years. He has developed cost recovery methods using knowledge databases and he has worked in oil and gas fields as a petroleum geologist as well as for spill response and cleanup, and lease valuation. He has developed exposure pathways, geological conduits for contaminants and sensitive receptors studies and risked-based environmental management methods to define site conceptual models for remedial actions and case closure. He uses bioremediation for groundwater cleanup, as well as chemical oxidization methods for in-situ cleanups.

He has performed dozens of peer reviews of environmental consultant and contractor invoices and cost recovery projects for insurance companies. He is a 4-time Senior Fulbright Scholar award winner, and he co-authored 4 books on oil spills and gas leaks, MTBE, Chromium VI, and acid mine drainage (AMD). He is an elected public official at a sewer plant and community services district associated with sewage, refuse and recycling. He is a certified hydrogeologist, and professional geologist in several states, including California and western states. He has worked for both plaintiffs as well as defendants. Many of the cases involve exposure of workers, children or others to chemical hazards through vapor, water or soil media. He works with interdisciplinary teams to answer complex exposure and groundwater and soil impact questions. He is an expert in industrial history investigation and forensic geologic sampling to obtain samples that are representative and reproducible that can accurately reflect subsurface conditions.

As a licensed engineering contractor (driller, builder, haz-mat removal, asbestos, etc.), he is also responsible for employee exposures and safety. Consequently he has worked with cases related to employee safety issues.

He values environmental impairment of commercial and industrial properties for estate and insurance purposes and appraises oil and gas interests for value and environmental impacts. He has performed hundreds of Phase I Environmental Assessment projects for due diligence and the subsequent Phase II Subsurface Investigation for soil, soil vapor and groundwater sampling.


Through an attorney, he reviewed a claim of $10+ million dollars at an oil field for a request for reimbursement to the insurance company. After a lengthy review of several dozen sites at the oil field, a total of about $3 million dollars were determined to be reasonable based on a variety of standardized criteria and factors. The settlement was favorable for the insurance company.For an attorney, he reviewed an expert's geophysical requests for a scope of work and determined that it was completely unreasonable and not possible technically. Using the information, the attorneys negotiated a favorable settlement.Working with a defendant regarding a lawsuit to compel the tenant to perform storm water monitoring and sampling, he was instrumental in developing the technical strategy to move the case toward settlement. He oversaw the stormwater sampling plan, and prepared the reports for the parties.He worked for the plaintiff who purchased the property from a company that did not disclose fully the activities that may have occurred on the property. After a detailed review of the history of the site, he was involved with protecting the current land owner and resolution of the litigation is ongoing, provided that the future financial liabilities of addressing the impacted soil should future use differ significantly from current use (excavation and disposal of impacted soil is expensive).He worked with a shopping center owner (and their attorney) on cost recovery for PCE impacted sewer leaks by the dry cleaning businesses which had been on site since 1968. Over a series of assessment tasks (passive soil vapor studies, well installation and remediation), case closure is pending. By using the passive vapor study early in the project, the leak of PCE from damaged sewer lateral lines was found early on, saving considerable money for the land owner.
