  • Study to Uncover Yellowstone’s Subsurface Mysteries

    A new study providing an unprecedented regional view of the earth’s crust beneath Yellowstone National Park will begin with a helicopter electromagnetic and magnetic (HEM) survey on November 7, 2016. Scientists from the U.S. Geological Survey, University of Wyoming and Aarhus University in Denmark hope to distinguish zones of cold fresh water, hot saline water, steam, clay and unaltered ...

  • Grand Challenges: Request for Information on the Subsurface

    Subsurface reservoirs account for more than 80% of U.S. primary energy, and they offer vast potential for the storage of energy, CO2, and nuclear waste. Despite decades of development, current technologies do not allow full utilization of subsurface energy resources. Major advances in our understanding of the subsurface environment coupled with the identification and development of potential ...

  • Further clues about subsurface oil movements

    The National Oceanic and Atmospheric Administration (NOAA), the US Environmental Protection Agency (EPA) and the White House Office of Science and Technology Policy (OSTP) have released its second peer-reviewed, analytical summary report about subsurface oil monitoring in the Gulf of Mexico. The report contains preliminary data collected at 227 sampling stations extending from one to 52 ...

  • Groundwater movement and contaminant transport in the Earth’s subsurface are the focus of two 2017 Darcy lectures

    Quantifying water movement and contaminant transport in the Earth’s subsurface are the critical issues addressed during presentations offered through the 2017 Henry Darcy Distinguished Lecture Series in Groundwater Science. Earth’s subsurface is part of the “critical zone” — the layer of the planet from the tops of the trees to the bottom of groundwater. This zone is ...

  • ASTM D5777 - 00(2011)e1 standard guide for using the seismic refraction method for subsurface investigation

    This guide summarizes the equipment, field procedures, and interpretation methods used for the determination of the depth, thickness and the seismic velocity of subsurface soil and rock or engineered materials, using the seismic refraction method. Measurement of subsurface conditions by the seismic refraction method requires a seismic energy source, trigger cable (or radio link), geophones, ...

  • Supersaturated Water Injection

    Passive Gas infusion is a patented technology that efficiently dissolves high concentrations of CO2 into water at elevated pressures. Supersaturated Water Injection (SWI) is an effective technology for NAPL recovery. CO2 supersaturated water injected into the subsurface results in the nucleation of CO2 bubbles at and away from the injection point. As the supersaturated liquid flows through the ...

  • New Storm Water Chamber Introduced

    The new StormTech® chamber developed to contain and control storm water runoff in an underground system is now available from Advanced Drainage Systems, Inc. (ADS). The StormTech MC-4500™ chamber is designed in accordance with AASHTO and ASTM design standards, making it a qualified choice for use in commercial and municipal projects. Manufactured using ...

  • MOE presents: provincial water monitoring networks

    Dave Rudolph – "Emerging Needs for Temporal and Spatial Data Precision" Dave Rudolph, with the University of Waterloo, started the symposium off with a very thought provoking presentation on the value of data. Dave used case studies to illustrate how different factors impact the quantity and quality of water resources, and how a small change can affect these conditions quickly and ...

  • Schlumberger Water Services launches new CTD-Diver

    Schlumberger Water Services (SWS) announced today the release of the new CTD-Diver* groundwater datalogger, which is engineered to further improve groundwater monitoring of municipal groundwater supplies, saltwater intrusion, injected wastewater, and water levels and tailings migration at mine sites. “CTD-Diver has an improved compact ceramic housing that will provide increased reliability when ...


  • Rising carbon dioxide and ‘acidified` waters in puget sound

    Scientists have discovered that the water chemistry in the Hood Canal and the Puget Sound, US, main basin is becoming more "acidified," or corrosive, as the ocean absorbs more carbon dioxide from the atmosphere. These changes could have considerable impacts on the region"s shellfish industry over the next several decades. The study, co-sponsored by NOAA, the University of Washington Applied ...

  • Artificial water systems create unintended consequences

    Amidst the semi-arid stretches of Phoenix, a visitor might blink twice at the sight of a sailboat cutting across the horizon. Tempe Town Lake, on the northern edge of Arizona State University, is just one of a multitude of lakes, small ponds, canals and dams combining flood control, water delivery, recreational opportunities and aesthetics, and altering perception of water availability and ...

  • US river flows altered by water management

    The amount of water flowing in streams and rivers has been significantly altered in nearly 90% of waters that were assessed in a new nationwide USGS study. Flow alterations are a primary contributor to degraded river ecosystems and loss of native species. Flows are altered by a variety of land- and water-management activities, including reservoirs, diversions, subsurface tile drains, groundwater ...

  • Schlumberger Water Services launches AquaChem 2010

    Schlumberger Water Services (SWS) announced today the release of AquaChem* 2010 water data analysis software. This latest release will improve the way geochemists, environmental consultants, and government agencies interpret water quality data that influence decisions in the management of municipal water resources, mine water quality, contaminated sites, and oilfield water supply and disposal. ...


  • Xylem launches new ‘FerryBox’ water quality monitor

    Xylem Analytics UK and Aanderaa Data Instruments have launched a new marine water quality monitor which has been designed to enable wider deployment of water quality sensors on ferries and other marine vessels. The ‘SOOGuard’ will be launched at Ocean Business 2013 in April and Xylem’s David Goldsmith says: “In order to encourage the operators of ferries to allow the ...

  • Ocean salinities show an intensified water cycle

    The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the ...

  • New model simulates US groundwater and surface water interactions

    A new model to simulate groundwater and surface water interactions has been released by the U.S. Geological Survey (USGS). The groundwater and surface water FLOW (GSFLOW) model simultaneously accounts for climatic conditions, runoff across the land surface, subsurface flow and storage, and the connections among terrestrial systems, streams, lakes, wetlands, and ground water. 'GSFLOW can be used ...

  • Alta Mesa Services, L.P., Fined for Violating the Clean Water Act

    The Environmental Protection Agency has fined Alta Mesa Services, L.P., of Houston, Texas, $29,400 for violating federal Spill Prevention Control and Countermeasure (SPCC) regulations at two of its oil production facilities in Terrebonne Parish, Louisiana. A May 1, 2012, federal inspection at the facilities found numerous violations including: failure to adequately conduct and document facility ...

  • New Studies Aid in Optimizing Water Use in Geothermal Applications

    Three key reports from the Energy Department address water impacts in geothermal energy production.
