The model consists of a number of modules which predict concentrations at a receptor due to transport in the subsurface, surface water, or air. The distribution diskettes contain application and theory manuals for the use of MULTIMED in modeling Subtitle D land disposal facilities (refer to FILE NAME AND CONTENT section). When applying MULTIMED to Subtitle D facilities, the landfill, surface water, and air modules in the model are not accessible by the user; only flow and transport through the unsaturated zone and transport in saturated zone can be considered. A steady-state, one-dimensional, semi-analytical module simulates flow in the unsaturated zone. The output from this module, water saturation as a function of depth, is used as input to the unsaturated zone transport module. The latter simulates transient, one-dimensional (vertical) transport in the unsaturated zone and includes the effects of longitudinal dispersion, linear adsorption, and first-order decay. The unsaturated zone transport module calculates steady-state or transient contaminant concentrations. Output from both unsaturated zone modules is used to couple the unsaturated zone transport module with the steady-state or transient, semi-analytical saturated zone transport module. The latter includes one-dimensional uniform flow, three-dimensional dispersion, linear adsorption, first-order decay, and dilution due to direct infiltration into the groundwater plume. The fate of contaminants in the various media depends on the chemical properties of the contaminants as well as a number of media- and environment-specific parameters. The uncertainty in these parameters can be quantified in MULTIMED using the Monte Carlo simulation technique. To enhance the user-friendly nature of MULTIMED, a preprocessor, PREMED, and a postprocessor, POSTMED, have been developed. The preprocessor guides the user in the creation of a correct Subtitle D input file by restricting certain options and parameters and by setting appropriate defaults. NOTE: This program installs only the MULTIMED model documentation that includes application and theory manuals for the use of MULTIMED in modeling Subtitle D land disposal facilities. _________________________________________________________________ DOCUMENTATION Copies of the following documents are included on the distribution diskette set. Refer to FILE NAME AND CONTENT section for further information.

These documents should be retained by the requester for future reference. The files READ.ME and RESPONSE.TXT are ASCII (non-binary) text files that can be displayed on the monitor screen by using the DOS TYPE command (e.g., TYPE READ.ME) or printed using the DOS PRINT command (e.g., PRINT READ.ME). File names with a file name extension of ".EPS" are encapsulated, post-script files that can only be printed using the DOS PRINT or COPY command. File names with a file name extension of ".WP5" are WordPerfect document files that can only be printed by selecting the print option (i.e., ) within WordPerfect. NOTE: If WordPerfect for Windows is used to print the WordPerfect files, use the standard WordPerfect printer drivers, not the WordPerfect printer drivers for Windows. _________________________________________________________________ DISTRIBUTION DISKETTES NOTE: k=1,024; m=1,048,576; b=1 byte Included are 2, 3.5 inch (1.44mb, DS/HD) PC DOS (Disk Operating System) formatted diskettes containing version 1.01 (December 1992) of the documentation for the Multimedia Exposure Assessment Model (MULTIMED). To install the MULTIMED model documentation files on a local hard or remote local area network (LAN) disk (hence forth referred to as a hard disk), insert the first distribution diskette in a compatible diskette drive. Then type A:\INSTALL or B:\INSTALL at the DOS system prompt and press the key. Then follow instructions and respond to the prompts presented on the monitor screen by the interactive installation program. NOTE: If the MULTIMED model documentation files are being installed from the MULTIMED documentation installation file (INSTALMD.EXE) downloaded from the CEAM electronic bulletin board system (BBS), then the user should type INSTALMD at the DOS system prompt and press the key. This command assumes that the current default drive and sub-directory is the same drive and sub-directory that contain the file INSTALMD.EXE. For further information on the CEAM BBS, refer to the TECHNICAL HELP CONTACT section. NOTE: The contents of the distribution diskettes can be copied to other "backup" diskettes using the DOS DISKCOPY command. Refer to the DOS Reference Manual for command application and use. The "backup" diskettes must be the same size and storage density as the original source diskettes. The following FILE NAME AND CONTENT section provides a brief functional description of each file by name or file name extension type. _________________________________________________________________ FILE NAME AND CONTENT The self-extracting, interactive executable program file on the distribution diskettes exist in a compressed format to save diskette space and file transfer time. This section contains a description of each file that can be decompressed from the compressed distribution file. Follow the instructions on the diskette label to install, decompress (extract), and restore documentation file(s) to their original name and size in order to place the MULTIMED model documentation files in a usable format on the hard disk. For comparison purposes, the original date and time of creation are also restored with each file. NOTE: Execution of the INSTALL or INSTALMD command can extract one or more MULTIMED model documentation files. These files are automatically stored into DOS sub- directories on the hard disk. The sub-directory structure, under which the sub-directories shown below are stored, is selected by the user during execution of the INSTALL or INSTALMD program. The string "InstallationDirectory" will be used to denote the highest level default installation directory structure chosen by the user during execution of INSTALL or INSTALMD. The files are listed by DOS sub-directory name. ** Sub-directory InstallationDirectory: READ.ME - MULTIMED model documentation general information and user support guide.
