Geochemistry Expert Witnesses
Geochemical data underpins decisions worth billions of dollars, from the grade of an ore body and the allocation of commingled oil production to the extent of subsurface contamination and the storage capacity of a carbon sequestration site. When those numbers prove wrong, mining companies sue the consultants and assay laboratories behind an overstated resource estimate, joint venture partners contest the fluid fingerprinting used to divide production, and developers pursue environmental firms whose site characterizations missed a contaminant plume. Similar disputes follow failed groundwater monitoring reports, skewed geothermal reservoir models, and industrial water treatment programs that did not prevent predictable scaling. The recurring question is whether the sampling, analysis, and interpretation behind a geochemical conclusion met the standards a competent professional would apply.
A geochemistry expert tests that question at its source, examining sampling design, chain of custody, laboratory calibration, and the models used to translate analytical results into resource, contamination, or performance conclusions. Re-assaying archived samples, reprocessing raw fluid or isotope data, or re-running a reactive transport model with the original inputs can reveal whether an error lay in the field, the laboratory, or the interpretation. That distinction drives causation, since it separates losses caused by a defendant's flawed work from the natural heterogeneity of the subsurface that no reasonable method would have captured. The resulting opinions frame professional negligence and contract claims, supply damages experts with corrected grades, volumes, or remediation scopes, and give counsel a disciplined basis for challenging an opposing expert's data selection.
Because geochemistry spans mineral exploration, petroleum systems, aqueous chemistry, and environmental contamination, an effective expert must have worked with the specific materials and methods in dispute. The geochemists we present include the author of a widely used textbook on the chemistry of surface and groundwaters who has consulted for federal agencies, an isotope geochemist holding a U.S. patent on isotopic analysis of chlorinated solvents, and specialists in uranium and precious metal deposits, petroleum reservoirs, and fluid-rock reactions. Others bring marine and energy experience, including testimony on seafloor installations, oil and gas exploration, and offshore operations. Round Table Group draws on more than 75,000 expert searches for litigators to connect counsel with geochemists whose experience matches the evidence.
