Geologic and hydrologic data for the municipal solid waste landfill facility, U.S. Army Air Defense Artillery Center and Fort Bliss, El Paso County, Texas

April 1, 2000

Geologic and hydrologic data for the Municipal Solid Waste
Landfill Facility on the U.S. Army Air Defense Artillery Center and
Fort Bliss in El Paso County, Texas, were collected by the U.S.
Geological Survey in cooperation with the U.S. Department of the
Army. The 106.03-acre landfill has been in operation since January
1974. The landfill contains household refuse, Post solid
wastes, bulky items, grass and tree trimmings from family
housing, refuse from litter cans, construction debris, classified
waste (dry), dead animals, asbestos, and empty oil cans. The
depth of the filled areas is about 30 feet and the cover, consisting
of locally derived material, is 2 to 3 feet thick.

Geologic and hydrologic data were collected at or adjacent to
the landfill during (1) drilling of 10 30- to 31-foot boreholes
that were completed with gas-monitoring probes, (2) drilling of
a 59-foot borehole, (3) drilling of a 355-foot borehole that was
completed as a ground-water monitoring well, and (4) in situ
measurements made on the landfill cover. After completion, the gas-
monitoring probes were monitored on a quarterly basis (1 year
total) for gases generated by the landfill. Water samples were
collected from the ground-water monitoring well for chemical
analysis.

Data collection is divided into two elements: geologic data
and hydrologic data. Geologic data include lithologic
descriptions of cores and cuttings, geophysical logs, soil-
gas and ambient-air analyses, and chemical analyses of soil.
Hydrologic data include physical properties, total organic carbon,
and pH of soil and sediment samples; soil-water chloride and
soil-moisture analyses; physical properties of the landfill cover;
measurements of depth to ground water; and ground-water chemical
analyses. Interpretation of data is not included in this report.
