Virginia L McGuire
Virginia (Ginny) McGuire is an emeritus Hydrologist with the U.S. Geological Survey Central Plains Water Science Center, based in Lincoln, Nebraska.
Virginia (Ginny) McGuire has worked as a hydrologist for the U.S. Geological Survey (USGS) Nebraska Water Science Center since April 1992. In 2013, she became the Center's Groundwater Specialist; in 2017, she became the Center's Report Specialist. Ginny has worked on a variety of projects dealing with aquifer characteristics, groundwater quality, and hydrogeologic framework. Ginny now was retired and is finishing up her work as an emeritus hydrologist.

High Plains Water-Level Monitoring Study
The High Plains aquifer underlies 111.8 million acres (about 175,000 square miles) in parts of eight States—Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. In response to a directive from Congress, the U.S. Geological Survey (USGS), in cooperation with local, state, and federal entities, has collected water-level data from wells screened in the High Plains...
Groundwater-Quality Monitoring near Ashland, Nebraska
Since 1991, the USGS Nebraska Water Science Center has collected water samples from six monitoring wells in the Platte River alluvial aquifer near Ashland. Analytes include major and trace metals, nutrients, dissolved organic carbon, pesticides and their degradates, and arsenic species. The samples are analyzed by the USGS National Water Quality Laboratory. The USGS also collects additional...
Integrating GRACE Satellite and Ground-based Estimates of Groundwater Storage Changes
Groundwater storage depletion is a critical issue for many of the major aquifers in the U.S., particularly during intense droughts. The GRACE (Gravity Recovery and Climate Experiment) satellites launched in 2002, with sensors designed to measure changes in the Earth’s gravitational field at large spatial scales (≥ ~200,000 km2). These changes are primarily driven by changes in water...
