    The importance of groundwater monitoring

    Groundwater monitoring is an essential element in any environmental information system. Based upon validated groundwater monitoring data, information is derived on which decisions can be made. Constant monitoring provides the necessary data input for your smart environment and is basically the basis of the decision making process concerning spatial planning and climate change adaptation. As in ...

  • Technical Announcement: Bacteria No Match for Deep Floridan Aquifer

    A first of its kind study has the potential to impact future regulatory decisions on disinfection practices for water prior to its recharge or following its storage in the Floridan Aquifer. The U.S Geological Survey report found that coliform bacteria die off faster in a regional aquifer system ...

  • Idaho aquifer decline could hinder radioactive monitoring

    A continued drop in underground water levels could make it more difficult to monitor the movement of radioactive contamination in an aquifer below an eastern Idaho nuclear facility, scientists say. Researchers with the U.S. Geological Survey in a 36-page report released Monday said the Eastern Snake River Plain Aquifer level has dropped below ...

  • High resolution multi-level monitoring for bedrock aquifers

    This presentation describes a comprehensive approach for determining the nature, extent, transport and fate of contaminants at industrial sites on fractured rock, with emphasis on sedimentary rock, referred to as the Discrete Fracture Network (DFN) approach. Development of this DFN approach began at a sandstone site in California in 1997, where the initial version of a method for measuring ...

  • USGS Releases First Tool Since 1980s Assessing Water Availability in Northern High Plains Aquifer

    A new U.S. Geological Survey publication and model can be applied by multiple entities to better understand flow, quantity, sources and sinks of groundwater in the Northern High Plains Aquifer, which covers approximately 100,000 square miles across Nebraska, South Dakota, Kansas, Colorado and Wyoming. “An ...

  • Arsenic: when will the clean water start flowing?

    Razia Begum has been asking the same question for two years now: 'Please will someone fix my arsenic filter?' She lives in Nagda, a village in one of the areas of Bangladesh most severely contaminated by arsenic in drinking water — although at first glance there is nothing about the village's lush paddy fields to suggest anything dangerous. Razia's family, like many thousands of others in such ...

  • Study Assesses Threats to Groundwater Availability and Sustainability in Northern Atlantic Coastal Plain

    Scientists Look at Issue from Long Island to North Carolina Threats to groundwater availability and sustainability in the Northern Atlantic Coastal Plain are dependent to a large degree by the type of aquifers used for water supply, according to a new regional assessment by the U.S. Geological Survey. The water challenges ...

  • Groundwater footprint reveals unsustainable water consumption

    Reservoirs of water stored under the earth’s surface, otherwise known as groundwater, are a valuable resource. However, using a footprinting method, a new global study has indicated that about 1.7 billion people live in areas where groundwater is being used more quickly than it can be replenished. Groundwater supplies water to billions of people and is important for agricultural ...

  • Silixa to attend the European Geosciences Union General Assembly 2014 in Vienna, Austria

    The EGU General Assembly 2014 will bring together geoscientists from all over the world to discuss their ideas with experts in all fields of geosciences. The event will take place between 27 April – 02 May, 2014. Silixa will present on “Monitoring borehole flow dynamics using heated fibre optic DTS in a fractured rock aquifer” on Tuesday, 29 April 2014, at 17:30, in board room ...

  • Groundwater threat to rivers worse than suspected

    In an address to the Groundwater 2010 Conference in Canberra, CSIRO Water for a Healthy Country Flagship scientist, Dr David Rassam, said land-use practices that reduce groundwater recharge into rivers and streams could significantly reduce low flows in nearby rivers and streams. “Many rivers are highly dependent on ‘base-flow’ from groundwater to keep running through dry times ...

  • Our World’s Water is Diminishing, But How Fast?

  • USGS Groundwater Model: New Tool for Communities in Northern and Central Arizona

    A new groundwater model of the interconnected aquifers in central and northern Arizona was released today by the U.S. Geological Survey, following a multi-year development effort that involved the Arizona Department of Water Resources and regional cooperators.  The computer model, known as the “Northern Arizona Regional Groundwater-Flow Model,” simulates how recharge from ...

  • Pesticide pollution slow to reach groundwater

    Underground water aquifers are a significant source of drinking water. In a recent study, French researchers found that pesticides applied to crops can take many years to sink down through the ground and reach groundwater. This means that they may still be entering aquifers, even after agricultural application has stopped. Groundwater is found underground in absorbent layers of rock. ...
