Jason Conder is a Principal Scientist based in California with more than 15 years of experience focused on risk assessment and contaminated sediments in contaminated site assessment and management, environmental toxicology, and ecological and human health risk assessment.


Jason has advised numerous large, multi-stakeholder client and client groups at contaminated sediment and uplands sites in North America, Europe, and Asia on matters relating to chemical fate, risk assessment, remediation, and chemical liability. His diverse responsibilities have included conceptualization and project management of remedial investigation and feasibility study programs, design and management of field investigations, advanced modeling, statistics, visualization of data, litigation support and expert witness testimony, remedial cost allocation and liability analysis, and preparation of strategic guidance for clients with large programmatic needs. Jason has extensive experience working on and supporting multi-million-dollar sediment sites and conducting preliminary risk and chemical fate assessments at several sediment and uplands sites in the US.

Of note, Jason focuses on evaluations of emerging chemicals of concern such as per- and polyfluoroalkyl substances (PFAS), including several product- and site-specific fate and risk assessments. He has published more than 20 peer-reviewed articles in environmental toxicology and chemistry, including two review articles on PFAS use, fate, and bioaccumulation. He has also presented technical work at numerous international scientific conferences and has served on and co-chaired several technical workshops.

Jason continues to advance the state-of-the-practice in contaminated sediments and risk assessment. He has published more than 20 peer-reviewed articles in sediment management and environmental toxicology and chemistry, presented technical work at numerous international scientific conferences, and has served on and co-chaired several technical workshops. He is currently developing and patenting an innovative passive sampling technique to improve the cost-effectiveness and quality of chemical availability evaluations for sediment porewater, soil, and surface water.
