This digital data set defines the boundary of the steady-state ground-water flow model built by
IT Corporation (1996). The regional, 20-layer ground-water flow model was developed for the
Underground Test Area (UGTA) Phase I project to simulate the Nevada Test Site and surrounding
areas. The model was used for estimating the amount of water moving through the ground-water
system, predicting the movement of contaminants, evaluating uncertainty in these predictions,
and supplying boundary conditions for more detailed models of the underground testing areas.
The U.S. Geological Survey integrated the IT Corporation (1996) model with the ground-water
flow model by D'Agnese and others (1997) to develop a transient flow model of the Death
Valley regional ground-water flow system (DVRFS) for the Department of Energy in 2004
(see "Larger Work Citation", Chapter A, pages 7-9, for details).

The boundary of the ground-water flow model by IT Corporation (1996) was used to develop the
subsequent lateral boundary of the transient ground-water flow model of the Death Valley regional
ground-water flow system (see "Larger Work Citation", figure A-2, p. 10).
The boundary of the ground-water flow model by IT Corporation (1996) is one of many spatial
layers in a spatial database supporting the USGS DVRFS project. This 5-year (1998-2004)
project, completed in cooperation with DOE and other Federal, State, and local agencies,
developed this spatial database for a regional-scale, 3D hydrogeologic framework model
(HFM) and a ground-water flow model. The models are intended to address water-resource
issues and the potential movement of radioactive material from the Nevada Test Site or the
proposed high-level nuclear waste repository at Yucca Mountain, Nevada.
Data from two previous ground-water flow models of the greater Death Valley region
(see "Larger Work Citation", Chapter A, p. 7) were the foundation of the DVRFS geospatial
database. These and other data were reexamined through a series of regional-scale hydrologic
investigations to provide updated and spatially consistent interpretations for the DVRFS study.
In some cases, new data were collected to augment the existing information. Data compiled
from the studies include natural ground-water discharge occurring through evapotranspiration
and spring flow; ground-water pumping for the period 1913-98; ground-water recharge simulated
as net infiltration; ground-water inflow and outflow at lateral model boundaries; hydraulic
conductivity and its relation to depth and other rock properties; and the estimation of water levels
representative of prepumped and pumped conditions in the region. Digital elevation models,
geologic maps, borehole information, cross sections, and other 3D models were used to develop
the HFM which represents the geometry of 27 hydrogeologic units and structural features. The
resulting geospatial database supports characterization and conceptualization of the DVRFS,
construction of 3D hydrogeologic framework and ground-water flow models, and visualization
of analysis and model results.

Spatial data sets supporting the Death Valley regional ground-water flow system (DVRFS) project were developed in cooperation with the U.S. Department of Energy's (DOE) National Nuclear Security Administration/Nevada Site Office (NNSA/NSO) Underground Test Area (UGTA) project of the Office of Environmental Management, the NNSA/NSO Hydrologic Resource Management Program (HRMP), the Office of Civilian Radioactive Waste Management's (OCRWM) Office of Repository Development (ORD), the NNSA/NSO Maintenance of Test Capability (MTC) program, and the National Park Service (NPS).

Attributes added by the GIS and the data set author were checked by inspection using a GIS. In addition, attributes were checked and evaluated as part of the review process associated with the publication of the source report.
Lines forming the polygon join at endpoints to completely enclose the area. Lines do not intersect, and no duplicate line features exist. All endpoints are represented by a single coordinate pair which indicates the beginning or end of a line.
The polygon feature in this data set was developed by IT Corporation (1996) and acquired digitally by the U.S.Geological Survey. The data set is complete and is not anticipated to change.
Horizontal positional accuracy of line features in the data set was tested by visually comparing hard copy plots to the original digital source data.

Line features forming the lateral boundary of the ground-water flow model by IT Corporation (1996) were acquired by the USGS as Drawing Exchange Format (DXF) files (R. Waddell, IT Corporation, written communication, 1999). The DXF file containing the boundary geometry was converted to a shapefile using a GIS; the resulting polygon feature was attributed by the author (Point of Contact).
