This report contains listings of model input and output files
for the simulation of the time of arrival of landfill leachate at
the water table from the Municipal Solid Waste Landfill Facility
(MSWLF), about 10 miles northeast of downtown El Paso, Texas. This
simulation was done by the U.S. Geological Survey in cooperation
with the U.S. Department of the Army, U.S. Army Air Defense
Artillery Center and Fort Bliss, El Paso, Texas. The U.S.
Environmental Protection Agency-developed Hydrologic Evaluation of
Landfill Performance (HELP) and Multimedia Exposure Assessment
(MULTIMED) computer models were used to simulate the production of
leachate by a landfill and transport of landfill leachate to
the water table. Model input data files used with and output files
generated by the HELP and MULTIMED models are provided in ASCII
format on a 3.5-inch 1.44-megabyte IBM-PC compatible floppy disk.
