Our litigation support staff have outstanding academic, professional, and scientific credentials to provide attorneys with sound technical and scientific foundations for case preparation.  We go beyond simply repeating the facts—we deliver context and insight to the questions at hand and present our findings in a clear and understandable way.


Our team has experience in multifaceted, high-stakes toxic tort litigation for a wide range of legacy and emerging contaminants.  From source and transport to exposure and effects, we utilize our skills and experience to build scientifically based expert opinions.  We combine our technical acumen with an exceptional ability to convey highly technical, scientific opinions in a narrative that is understandable by judge and jury.

Identifying contaminant sources and the timing of their release is an important factor in understanding chemical fate and transport, assessing remedial actions, and resolving complex questions concerning contribution, source attribution, and cost allocation.  Our forensic specialists excel at deconstructing the evidence and building fact-based cases to address these important issues.  With our subject matter expertise and innate multidisciplinary perspective, we provide fresh insights that are robust, credible, and compelling.

Issues of divisibility, contribution, cost recovery, and allocation frequently arise when addressing response costs at multiparty environmental sites.  We employ scientifically defensible technical analyses to support divisibility, and develop equitable allocation or apportionment plans.  By analyzing the facts related to source, release, and fate along with information on operational history and/or use, we build robust allocation approaches.

Our clients turn to us for support with natural resource damage claims.  We have substantial experience preparing defensible strategies for all phases of the natural resource damage assessment (NRDA) process—from developing a technically sound basis for evaluating injury, causation, and baseline, to quantifying losses and assisting with cooperative assessments.  Our NRDA services are fully integrated with our forensic practice so we can assist in allocation matters as they arise.
