Subsurface Flow and Transport
Additional Information
EMSL users can employ subsurface flow and transport capabilities to focus on the application of fundamental physical chemistry concepts to the study of chemical reactions in heterogeneous natural material, with an emphasis on soil and subsurface systems. EMSL's approach to subsurface flow and transport studies is holistic, integrating flow cells, analytical tools, and predictive modeling capabilities to study the fate and transport of environmental contaminants, including metals, radionuclides, and chemicals.
A variety of flow cells is available to EMSL users, including column, batch, radial, wedge, and rectangular flow cells as well as microfluidics instrumentation. Flow cells are used in coordination with high-precision, high-sensitivity analytical tools to generate data about sample characteristics by detecting the presence carbon, trace metals, ions, nonvolatile compounds, thermally labile chemicals, and more. EMSL users have the benefit of designing experiments using the predictive subsurface flow and transport simulator STOMP (Subsurface Transport Over Multiple Phases). Data derived from experiments using EMSL's subsurface flow and transport capabilities are used to further refine STOMP, ever increasing its precision.
