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.
The Story of the USGS Research Vessel (R/V) Polaris
For the past 50 years, the USGS has been conducting research in the San Francisco Bay and Delta, California and beyond. This research would not have been possible without the Research Vessel (R/V) Polaris . Many scientists who have been fortunate to work on the Polaris have come and gone, but the Polaris sailed from the South San Francisco Bay continuously from 1968 until her retirement in 2015.
Pore-Water Profiler, US Patent 8,051,727
Patent for a pore-water profiler and method for sampling pore water. The pore-water profiler includes a sample intake probe that receives the fluid to be sampled. (Full details provided by the U.S. Patent and Trademark Office website.)
Sequential, Time-Integrated Collector of Precipitation, Ground Water, and Surface Water for Analysis of Isotopes; US Patent 7,687,028
Patent for a sequential, time-integrated collector having an electronic controller that actuates either of two electrically-actuated valves, each connected to a water reservoir. (Full details provided by the U.S. Patent and Trademark Office website.)
Small-Scale, Hydrogen-Oxidizing Denitrifying Bioreactor, US Patent 6,863,815
A method for treating nitrate-contaminated water comprising treating said water with hydrogen-oxidizing denitrifying bacteria in the presence of hydrogen. (Full details provided by the U.S. Patent and Trademark Office website.)
Sorbant Sequestration and Removal of Toxic Metal Ions, US Patent 6,896,813
A matrix for water decontamination has an amended sorbant cellulose substrate with an iron (ferric) oxyhydroxide component and a component to sorb dissolved organic compounds retained by the cellulose substrate. (Full details provided by the U.S. Patent and Trademark Office website.)
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.)
Deep Aquifer Remediation System, US Patent 6,458,271
A groundwater decontamination system includes a decontamination unit adapted to be lowered down through a non-pumping well into an aquifer containing contaminated water. (Full details provided by the U.S. Patent and Trademark Office website.)
Aquifer Remediation Barrier for Removal of Inorganic Contaminants, US Patent 6,428,695
A permeable barrier for decontaminating groundwater having two distinct components for increasing contaminant removal. Preferably, the barrier material is a mixture or distinct layers of bone-char phosphate material and iron oxide pellets. (Full details provided by the U.S. Patent and Trademark Office website.)
Selenate Removal from Waste Water, US Patents 5,271,831 and 5,009,786
A method and apparatus for removing selenate from waste water through the use of selenate respiring microorganisms under substantially anoxic conditions is described. The method includes a first zone for removing nitrate by assimilation into biomass. (Full details available at the U.S. Patent and Trademark Office website for patents 5,271,831 and 5,009,786.)
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.)
