Short description: The Center for Subsurface Modeling Support (CSMoS) provides public domain ground-water and vadose zone modeling software and services to public agencies and private companies throughout the nation. CSMoS is located in Ada, Oklahoma at the National Risk Management Research Laboratory (NRMRL), the U.S. EPA's Center for Ground-Water Research. The primary aims of CSMoS are to provide direct technical support to EPA and State decision makers in subsurface model applications and to manage and support the ground-water models and databases resulting from the research at NRMRL. This research encompasses the transport and fate of contaminants in the subsurface, the development of methodologies for protection and restoration of ground-water quality, and the evaluation of subsurface remedial technologies. As a result, a major focus of CSMoS entails coordinating the use of models for risk assessment, site characterization, remedial activities, wellhead protection, and Geographic Information Systems (GIS) application. In these ways, CSMoS performs an active role in protecting, restoring, and preserving our nation's ground-water resources. CSMoS provides direct technical assistance for a broad spectrum of modeling applications. Models and/or databases are available to accomplish the following tasks: * Site Characterization - chemical and soil characterization databases which provide values for required model input data * Geostatistics - models which produce statistics and semi-variograms for kriging of site data * Saturated Zone Groundwater Flow and Fate/Transport - two and three-dimensional single phase and multiphase flow models with fate and transport for unconfined and confined aquifers * Unsaturated Zone Groundwater Flow and Fate/Transport - one-dimensional single and multiphase flow with fate and transport for the vadose zone * Combined Unsaturated/Saturated Flow and Transport - two and three-dimensional single phase and multiphase flow models with fate and transport for the vadose and saturated zone * Natural Attenuation - one-dimensional screening models to assess if natural attenuation of fuel hydrocarbons or chlorinated solvents is occurring at a site and a two-dimensional model for predicting the natural attenuation of fuel hydrocarbons at a site. * Well Head Protection Assessment - models which enable steady state and time related capture zones to be determined for numerous pumping well scenarios in various site settings. These models can be used to assist in performing site characterization, groundwater flow and transport simulations and selecting groundwater remediation options at RCRA sites, Superfund studies, and also for the determination of Well Head Protection areas.
