Groundwater Modeling System

Technology

The Department of Defense (DoD) Groundwater Modeling System (GMS) is a software package that helps expedite environmental cleanup activities. This comprehensive graphical subsurface modeling environment incorporates a suite of numerical modeling programs that allow engineers and others involved in hydrodynamic modeling to visualize project sites, evaluate cleanup alternatives, and predict their effectiveness. It provides tools for every phase of a groundwater simulation, including site characterization, model development, post-processing, calibration, and visualization. GMS provides an integrated graphical environment for performing subsurface flow, contaminant fate/transport, and efficacy and design of remediation system evaluation studies.

Problem

In the past, due to a lack of understanding of the dangers associated with the handling and disposal of certain chemical compounds, the DoD has contributed to subsurface environmental problems at military installations around the world. Cleanup of these sites could take decades with cost estimates ranging into tens of billions of dollars.

Expected Cost to Implement

GMS is available at no cost to employees of the DoD, the Environmental Protection Agency (EPA), the Department of Energy (DoE), the Nuclear Regulatory Commission (NRC), or onsite contractors to these agencies. Commercial use is available through Aquaveo at www.aquaveo.com.

Benefits/Savings

GMS integrates and simplifies the process of groundwater flow and transport modeling by bringing together all of the tools needed to complete a successful study. GMS provides a comprehensive graphical environment for numerical modeling and tools for site characterization, model conceptualization, mesh and grid generation, geostatistics, graphical visualization, and remedial alternative evaluation. Using GMS can save time and money, as much as 20 percent on overall project remediation costs.

Status

GMS is available for Microsoft Windows-based operating systems. It is compatible with any system that runs Windows NT, 2000, or XP. The current version of GMS provides a complete interface for the codes FEMWATER, WASH123D, ADH, MODFLOW 2000, MODPATH, MT3DMS, RT3D, ART3D, SEAM3D, UTCHEM, MODAEM, SEEP2D, and UTEXAS4 as well as the parameter estimation codes PEST and UCODE.
