Provisional Data Statement
The U.S. Geological Survey (USGS), Nevada Water Science Center, in support
of the U.S. Department of Energy, Nevada Environmental Management Operations Activity, Underground
Test Area Study, conducts a hydrologic data-collection program at the
Nevada National Security Site (NNSS), formerly Nevada Test Site (NTS), and vicinity. As part of this data-collection program,
the USGS maintains an onsite and offsite well network for which water
levels are measured periodically. Data collected from these monitoring
networks are made available quarterly.
Depth-to-water measurements made as part of this task are provided for
the areas listed below.
As an additional part of the data collection program, the USGS
compiles water production reports supplied by National Security
Technologies, LLC (NSTec). Available production data from wells on the NNSS are compiled and used to estimate daily withdrawal rates.
Monthly withdrawals, calculated from the daily rates, are tabulated
at the end of each quarter.
