Groundwater-Level Response to Virginia Earthquake, August 23, 2011
A magnitude 5.8 (Mw) earthquake occurred at 1:51 pm EDT (17:51 UTC) on August 23, 2011, at a depth of about 3.7 miles (6 kilometers) beneath the town of Mineral, Virginia, located approximately 27 miles (45 kilometers) east of Charlottesville. The event is among the largest earthquakes recorded in the eastern United States.
Borehole Testing System, US Patent 6,761,062
A self-contained, transportable system for conducting any of hydrologic tests or water sampling techniques without the need for retooling or readjusting the system. (Full details provided by the U.S. Patent and Trademark Office website.)
Method and Apparatus for Steady-State Measurement of Liquid Conductivity in Porous Media, US Patent 4,679,422
In the operation of the present invention, a compacted porous medium is provided with a supply of the desired liquid and is subjected to centrifugal force until the measurement of the flow rate of liquid through the medium is substantially constant. (Full details provided by the U.S. Patent and Trademark Office website.)
Understanding Spectral Gamma: Fundamentals of Nuclear Geophysics
The principles essential to the interpretation of gamma, gamma-spectrometry, gamma-gamma, and various types of neutron logs include the nature of subatomic particles and the particles and photons emitted by unstable isotopes.
All about corrosivity
A U.S. Geological Survey assessment of more than 20,000 wells nationwide shows that untreated groundwater in 25 states has a high prevalence of being potentially corrosive. The states with the largest percentage of wells with potentially corrosive groundwater are located primarily in the Northeast, the Southeast, and the Northwest. These FAQs were written in conjunction with that study. In...
Aqueous Crystal Growth and Dissolution Kinetics of Earth Surface Materials
Although calcium carbonate reaction kinetics has important application in several areas of Earth Science, the mechanism of natural organic matter mediation of carbonate minerals growth and dissolution rates remains largely unknown. This project uses multiple approaches to study calcium carbonate formation and dissolution rates in surface water and groundwater systems.
Wyoming Groundwater-Quality Monitoring Network
A wide range of activities have the potential to contaminate groundwater. In addition, several naturally-occurring constituents can limit the suitability of groundwater for some uses. The State of Wyoming has established rules and programs to protect groundwater quality, as well as agencies to implement the rules and programs. The Wyoming Groundwater-Quality Monitoring Network (WGQMN) is one such...
