The FASTCHEM/trademark/ (Fly Ash and FGD Sludge Transport and Geochemistry) workstation for integrating pre- and postprocessing functions: Final report

The FASTCHEM/trademark/ (Fly Ash and FGD Sludge Transport and Geochemistry) package provides an interim computational capability that a utility manager can use to assess the effects of a waste-disposal site on the local groundwater system. The FASTCHEM/trademark/ package consists of six codes that combine current mechanistic and empirical understanding of factors influencing the migration of inorganic chemicals from utility waste-disposal facilities. The FASTCHEM/trademark/ workstation provides the main user interface to the package through a communications link to the mainframe computer. The workstation allows the user to create conceptual models of flow, transport, and geochemical processes. In addition, the workstation includes a postprocessor for preparing graphic output from the coupled geohydrochemical calculation. This document describes the organization of the workstation and its relation to the other codes in FASTCHEM/trademark/. Use of the workstation for developing conceptual models for hydrologic, geochemical, and transport processes is discussed. The workstation requires the use of an IBM/reg sign/ personal computer; installation of the workstation on the computer is performed by an IBM-DOS batch file, which is also described in this document. 23 refs., 91 figs., 14 tabs.
