Julie Chambon is a Senior Engineer based in California focused on groundwater remediation, flow and transport modeling, and water management and supply.
Julie has practical experience developing groundwater flow and fate and transport models to support a wide range of practical applications, including development of effective remediation solutions, well siting, contamination delineation, evaluation of remedial performance, and identification of data gaps. Julie has successfully constructed, calibrated, and used a variety of models, from large complex models to very simplified models, each tailored to the specific needs of the projects and clients. She is the lead modeler on several sites with complex groundwater flow conditions, including multiple CERCLA-regulated sites under USEPA regulatory oversight. Julie also applies her modeling expertise to support evaluation of fate and transport of emerging contaminants, including per- and polyfluoroalkyl substances (PFAS). She recently led the development and calibration of a groundwater flow and PFAS fate and transport model for Eielson Air Force Base in Alaska. Her experience also includes regional and basin-wide hydrogeological characterization and groundwater model development for groundwater resources evaluations under the California Sustainability Management Act (SGMA).
In addition to groundwater modeling, Julie helps clients with program management and site strategy, including support for regulatory interactions, stakeholder involvement, permitting, contractor coordination and communication.
Applying her expertise in chlorinated solvents, fate and transport modeling, and remedial design, Julie is collaborating with Virginia Tech on an Environmental Security Technology Certification Program (ESTCP) project for development of a volume-averaged model to estimate dense non-aqueous phase liquid (DNAPL) dissolution and remediation.
