Environmental Expert Witness Services

VERTEX’s environmental experts have evaluated complex technical issues including the source and timing of chemical or other releases, groundwater contaminant fate and transport, best practices of site cleanup and costs, Potential Responsible Party (PRP) investigations, data validity, and compliance of response actions with applicable regulations.

Our environmental experts have testified in hundreds of cases in state courts, federal courts, and arbitration. With a deep bench of Certified Industrial Hygienists (CIHs), Environmental Engineers (PEs), Professional Geologists (PGs), hydrologists, and other licensed experts, VERTEX’s team are qualified in hazardous building material claims, air quality claims, environmental spills, cost estimating, allocation, environmental remediation means and methods, subrogation, and claims management. We have evaluated complex environmental issues in dispute during litigation and formulated expert opinions for presentation in reports, depositions, and trial.

Many in the industry take a different approach, but at VERTEX, we recognize that expert witnesses are stronger if they are also actively working on projects. Choose VERTEX for your next case and gain environmental expert witnesses with current, real-world experience.
