Jason Conder

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 a variety of clients and multi-stakeholder client groups at contaminated sediment and uplands sites in North America, Europe, Australia, South America, 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 the strategic assessment and management of complex contaminated sediment sites. In addition, he continues to work on innovative passive sampling techniques to improve the cost-effectiveness and quality of chemical availability evaluations for sediment, soil, and surface water.

A significant portion of Jason's practice has focused on evaluating emerging chemicals of concern such as per- and polyfluoroalkyl substances (PFAS). As an internationally-recognized expert on PFAS, his work has included several product- and site-specific PFAS fate and risk assessments and he has published several articles on PFAS, including two peer-reviewed papers on PFAS use, fate, and bioaccumulation. He has also published two guidances for the US Department of Defense - a PFAS "Frequently Asked Questions" document and a guidance on PFAS ecological risk assessment.

Jason continues to advance the state-of-the-practice in contaminated sediments, risk assessment, and PFAS. 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.
