LFR has extensive experience in developing groundwater flow and chemical transport models for a wide range of hydrogeologic conditions. From analytical models used to estimate simple capture zones of pumping wells, to basin-wide multilayer numerical flow and transport models, our staff can select and effectively apply the necessary tools, from the application of basic hydrologic principles, to the analysis of the most complex flow regimes and chemical fate-and-transport mechanisms.

LFR has diverse experience in modeling a wide range of environmental flow and transport processes. These involve various environmental media, including vadose-zone gas and water, groundwater, sediment, surface water, and air. We have experience simulating the fate and transport of all major classes of chemicals, and we have particular expertise in multiphase flow modeling and multicomponent transport modeling, including the simulation of chemical transformations and biodegradation.
