Caliber Insights brings contaminant geoscience, environmental forensics, statistics, and data analytics to complex environmental matters. Defensible work, trusted by regulators and the clients we serve.
Caliber Insights is an environmental contamination and forensics consulting firm founded in 2025 by two principals: Matt Vanderkooy, a professional geoscientist, and Dr. Cathy Crea, a Ph.D. environmental statistician. Together they bring fifteen-plus years each on complex contamination matters across North America.
Caliber brings excellence to contamination matters. Source attribution. Background studies. Remedial alternatives. Trend analysis. Permitting and regulatory negotiation. Litigation support and expert testimony. We deliver work that withstands scrutiny.
Law firms, industrial clients, insurers, and the consulting firms they retain. Caliber is active across the United States and Canada.
Client objectives and sound science are at the heart of every delivery. Senior practitioners on every matter. Attention to detail paired with strategic analysis and direction. Findings communicated clearly and concisely and supported by detailed analysis. We perform our work with rigor and commitment.
Matt and Cathy founded Caliber Insights in 2025 after fifteen-plus years each on complex contamination matters across North America. Both lead client work directly, across the United States and Canada.
Fifteen-plus years directing contaminant assessment, remedy strategy, and PFAS programs at legacy and active sites. Recognized for foundational technical insights, regulatory communication, and leading multi-discipline teams under enforcement pressure.
Ph.D. environmental statistician specializing in advanced data analytics, multivariate statistics, and forensics. Subject matter expert to more than fifty teams on contamination and litigation matters. Methodology accepted by USEPA, State regulators, and the US Army Corps of Engineers.
Time series monitoring well data were evaluated for statistical trends. Across the wells with sufficient time series data, 30 percent showed statistically significant decreases. Among wells with decreasing trends, the magnitude of decrease varied by compound, with one PFAS species showing reductions averaging up to 73 percent.
We developed a set of data analyses and statistical evaluations that demonstrated, on a plume-level, that contaminant concentrations were decreasing. We utilized a combination of estimations of groundwater travel time, individual well time trend analysis, and plume-level concentration distribution evaluations to demonstrate this outcome.
Caliber Insights developed an LNAPL forensic framework assessment to evaluate the potential connection between LNAPL at two adjacent facilities. We developed this approach combining our skills in developing site Conceptual Site Models, data analytics, and environmental forensics. We identified key lines of evidence to provide a forensic basis to either establish or eliminate the LNAPL connection between the two facilities.
