Subtitle D Landfill Application Manual for the Multimedia Exposure AssessmentModel (MULTIMED)

摘要

The MULTIMED computer model simulates the transport and transformation ofcontaminants released from a hazardous waste disposal facility into the multimedia environment. The report is an application manual for the use of MULTIMED in modeling Subtitle D land disposal facilities (as described in the Resource Conservation and Recovery Act). For Subtitle D facilities, only the flow and transport components of MULTIMED are used in simulating leachate movement through the unsaturated zone and transport in the saturated zone. A 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. Instruction is provided for inexperienced as well as experienced model users who seek to study or design waste disposal facilities.
