  • Coordinated groundwater recharge needed

    The massive rains over California last month are not just a blessing but also a curse: a curse because the intensity of rain causes serious problems with flooding, erosion and landslides. Every watershed in California should therefore have a coordinated program to intentionally capture flood flows and recharge groundwater aquifers. Extreme weather is one reason so much reservoir storage has been ...

  • Celebrating Innovative Groundwater Management: Fifty Years of Groundwater Recharge with Recycled Water

    The following is being released by Water Replenishment District of Southern California: WHAT: Celebrating Innovative Groundwater Management: Fifty Years of Groundwater Recharge with Recycled Water. This event will mark the fiftieth anniversary of replenishing the region's groundwater basin (water ...

  • Climate change could affect groundwater recharge, scientists say

    (AXcess News) Washington - Elevated levels of carbon dioxide (CO2) in the Earth's atmosphere could seriously impact air, weather and vegetation. Now a scientist with the Agricultural Research Service (ARS) is taking a closer look at what could happen underground. If atmospheric CO2 levels double within this century, as many climate models predict, some areas could experience large increases in ...

  • Groundwater Recharge in Upper Colorado River Basin May Hold Steady Under Climate Change

    Future groundwater replenishment in the Upper Colorado River Basin may benefit from projected increases in future basin-wide precipitation under current climate projections, according to a recent study by the U.S. Geological Survey and Bureau of Reclamation. The Colorado River provides water for more than 35 million people in the United States and 3 million people in Mexico. A recent USGS ...

  • NGWA offers short course, `Artificial Recharge of Ground Water`

    The short course, “Artificial Recharge of Ground Water,” is being offered September 22-23 in Baltimore, Maryland, by the National Ground Water Association (NGWA). The course will cover well recharge types, objectives, sources of water, and wellhead and wellfield designs. It also will examine aquifer storage recovery (ASR) systems in aquifers with either freshwater or impaired groundwater. ...

  • Groundwater evaluation platform

    SuperGeo Technologies has developed a data platform for groundwater recharge areas in order to evaluate the recharge potential. The platform is able to assist researchers in delimiting groundwater recharge areas and also in determining parameters such as recharge rate, pumping rate, flow rate and recharge potential. Water resource protection is one of the most important policies in Taiwan. ...

  • Harnessing the benefits of groundwater

    This policy brief, published by the International Water Management Institute (IWMI), explores the role of groundwater storage in providing communities with wider access to water in the face of climate change. The use of groundwater for domestic water and irrigation has already lifted millions of small farmers out of poverty. But, for many regions, including the world's biggest groundwater user, ...

  • Treatment of abstracted groundwater

    Since abstracted groundwater can consist of a complex mixture of river bank filtrate and polder water, which have different origins and compositions, its treatment is challenging . An article in Drinking Water Engineering and Science discusses the effect of the properties of this mixture on the production of drinking water. In the Netherlands, over 60% of ...

  • AWWA Policy: Management of Groundwater

    The following revised AWWA Policy Statement on Management of Groundwater has been approved by the Technical and Educational Council for public comment. Comments on the policy statement will be reviewed by AWWA staff and forwarded to the Executive Committee if the comments are minor or referred back to the originating body if the comments are substantive. Policies forwarded to the ...

  • New map of global groundwater depths

    Despite groundwater’s importance to ecosystems, little is known about its global distribution. Researchers have now developed a model to map groundwater, revealing that ecosystems covering 22-32% of the Earth’s surface rely on this important resource. Groundwater is vital for many ecosystems, providing crucial support to plants and animals, especially during droughts. ...

  • Pesticides persist in groundwater, say SSSA

    Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations. The downward movement of pesticide degradation products, formed in situ, can also contribute to the contamination of ground water. Once in ground water, pesticides and ...

  • 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 ...

  • AUS$1.3m to improve groundwater management in regional Australia

    Minister for Climate Change and Water, Senator Penny Wong, has announced $1.3 million to better manage groundwater supplies from aquifers. Senator Wong made the announcement during a trip to Bourke on the last day of a three-day tour of the northern Murray-Darling Basin. 'Groundwater accounts for more than 30 per cent of our total water consumption - yet it is a finite resource which is only ...

  • Call for abstracts for NGWA Conference on Hydrogeophysics and Deep Groundwater

    The call for abstracts is now open for the NGWA Conference on Hydrogeophysics and Deep Groundwater that is taking place in March 2017. Abstracts are being sought for the NGWA Conference on Hydrogeophysics and Deep Groundwater in the following two tracks and are due October 31, 2016. Track 1 — Applications of Hydrogeophysics to Groundwater Characterization, ...

  • 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 ...

  • Impacts of groundwater on local rainfall under a changing climate

    Climate change is expected to bring hotter conditions to many important agricultural regions. This will affect rates of evaporation from the ground and may also have an impact on local rainfall patterns. A recent study suggests that the depth of groundwater may determine the susceptibility of a region to drought following changes in temperature and rainfall. Understanding the transfer of water ...

  • DuPont takes a lead in groundwater conservation for Florida

    Each person in the US state of Florida uses about 1,720-2,160 liters of water per day, and with thousands of people moving to the state each month, public water supply needs near DuPont's plant are expected to double by 2025. Drinking water comes from two sources: surface water and groundwater. Supplying drinking water to a growing state like Florida is a challenge because 90% of the state's ...

  • Groundwater availability detailed in California`s Central Valley

    A new, three-dimensional water-modeling tool provides a detailed picture of how water flows below ground and how it relates to surface-water in rivers and canals in California’s Central Valley. The Central Valley Hydrologic Model, developed by scientists at the U.S. Geological Survey, is available for use by water managers and other agencies. The model was designed to help resource agencies ...
