Chemical fate and transport consulting for regulatory compliance and dispute support.
Exponent provides rigorous assessment for challenging and novel environmental impacts, applying multidisciplinary expertise to evaluate the source, mechanism, and timing of environmental chemical releases. Our environmental scientists and engineers work closely with ecological and health scientists to understand exposure and effects and help navigate disputes and manage regulatory requirements.
Exponent's chemical fate and transport consulting services cover a broad spectrum of chemical contaminants across air, water, groundwater, soil, soil vapor, surface sediment, and house dust. We help clients understand all aspects of their challenge by leveraging our experts in hydrology, meteorology, microbiology, thermal and structural engineering, and investigative and failure analysis.
Exponent's scientists and engineers have published hundreds of peer-reviewed scientific articles on chemical fate and transport topics, such as the sources of chemicals, changes that occur when they are released to different environments, the transport of these chemicals, reconstruction of historical chemical releases, and exposure assessments. Our work combines empirical data, basic principles of chemistry and microbiology, and fate and transport models, and we've been recognized globally for our investigations, expert opinions, and publications on the fate and transport of chemicals in toxic tort, property damage, cost allocation, and Natural Resource Damage Assessment cases.
services
For 50+ years, we’ve thrived on solving unstructured problems that require bespoke solutions. Some of our services include:
• Site-specific conceptual site modeling to identify the key pathways from sources to receptors
• Evaluation of the reactions (abiotic or biological) that alter chemical forms and distributions in various media
• Determination of exposure to human and ecological receptors
• Geographical information systems and advanced data analysis to evaluate spatial and temporal trends in contaminant concentrations
• Numerical modeling to simulate chemical movement and transformation in surface waters, groundwater, unsaturated soil and sediments, and air
• State-of-the-art geochemical and hydrological numerical models developed for specific sites to understand chemical mobility in complicated environmental systems
