Description:
An analytical solution, called REMFuel (for Remediation Evaluation Model for Fuel hydrocarbons) has been developed for simulating the transient effects of groundwater source and plume remediation for fuel hydrocarbons. In the analytical method, the contaminant source model is based on a power function relationship between source mass and source discharge for multiple fuel constituents, and it can consider partial source remediation at any time after the initial release. The source model serves as a time-dependent mass flux boundary condition to the analytical plume model, where flow is assumed to be one-dimensional. The plume model for each fuel component simulates first order sequential decay and production of one daughter species. REMFuel can also simulate zero order or Monod‟s kinetics for decay of fuel components in the plume. The decay rates and other reaction coefficients are variable functions of time and distance in the plume. This approach allows for flexible simulation of enhanced plume remediation that may be temporary in time, limited in space, and which may have different effects on different contaminant species in the plume. The Center for Subsurface Modeling Support (CSMoS) at EPA has developed a Graphical User Interface (GUI), for REMFuel that will allow the user to quickly and easily evaluate the balance of LNAPL source remediation, plume remediation, and natural attenuation. The GUI consists of a user friendly, visually intuitive model parameter data entry screen, and a variety of quick and powerful ways of displaying the resulting model output. The primary objective of the REMFuel GUI is to simplify model data input, and viewing/interpreting model data output. The GUI is written in Visual Basic. It will compile the model input file, run the input file through the FORTRAN model code, and provide a seamless way of working with the resulting output data files. This beta version of REMFuel provides a suite of powerful tools for building and interpreting models. The manual will be periodically updated to include new functions and related theoretical background.
