Exponent provides state-of-the-art expertise in the field of chemical transport and fate. Our scientists and engineers have published hundreds of peer-reviewed scientific articles, and advised numerous government entities and industrial clients on chemical transport and fate issues. We have been recognized for our work in toxic tort, property damage, cost allocation, and Natural Resource Damage Assessment (NRDA) cases nationwide.
Exponent’s chemical fate-and-transport services cover a broad spectrum of chemical contaminants and involve evaluations in media such as air, water groundwater, soil, surface sediment, and house dust. We also evaluate remedial alternatives, apportion sources, and reconstruct exposure.
Exponent’s cost-effective, scientifically defensible, and realistic assessments begin with the development of a conceptual site model, which often identifies the key pathways that require evaluation.
We routinely provide expert evaluations based on conceptual site models and assessment of existing data. In cases where supplemental information is required, our scientists and engineers are accomplished at designing field and laboratory studies, and employing state-of-the-art experiments and methods to resolve scientific issues.
Exponent possesses strong capabilities in data evaluation and model prediction. This includes GIS and statistical capabilities to evaluate trends in contaminant concentrations in space and time. It also includes numerical modeling of chemical transport and fate in air, unsaturated soil, groundwater, sediments, and water bodies (rivers, lakes, estuaries, oceans). Depending on the specific project objectives, the numerical models developed by Exponent can range from simple to complex. Examples of the latter include state-of-the-art geochemical and hydrological models developed specifically by Exponent scientists and engineers to understand chemical mobility in multifaceted environmental systems.
Exponent provides unique synergy between environmental science and our failure analysis, drawing on engineering expertise in material failures , fires and explosions, and structural failures. We use this expertise when evaluating the source, mechanism, and timing of environmental releases. In addition, our environmental scientists and engineers work closely with ecological and health scientists, utilizing these capabilities to understand exposure and effects. This cooperation among the diverse Exponent practices provides our clients with unmatched value and resources in successfully managing their regulatory and litigation needs.
