Quarterly Update

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.
