  • 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 ...

  • Runoff research promotes healthier aquifers

    Where rain falls can influence the quality of surface water before it enters underground reservoirs, some of which provide water that eventually comes out of our taps. That's one conclusion from a collaborative study by the Agricultural Research Service (ARS) and the University of Arizona (UA). The ARS and UA scientists are investigating how urban landscapes influence storm runoff and water ...

  • 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 ...

  • Jaffna aquifer depleting from overuse

    The single limestone aquifer, which is the main source of freshwater in Sri Lanka's northern Jaffna peninsula, is gradually depleting through overuse, researchers say. "The area suffers from severe groundwater imbalance which might reach crisis proportions in the future," Shanti de Silva, one of two scientists who ...

  • 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 ...

  • 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. ...

  • 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 ...

  • ISMAR7, the premier event for aquifer management, is now accepting abstracts.

    Recognized as the world's pre-eminent conference devoted entirely to aquifer recharge, this event offers you access to the latest scientific advances, project case histories, and technological innovations in Managed Aquifer Recharge (MAR). ISMAR7 (the seventh in the conference series) will be held in Abu Dhabi, October 9 - 13, 2010 at the Armed Forces Officers Club (AFOC). ...


  • NGWA publishes best practices for groundwater professionals on aquifer storage and recovery

    A new set of best suggested practices (BSPs) for groundwater professionals involved in aquifer storage and recovery (ASR) projects has been approved by the National Ground Water Association (NGWA). First conceptualized in 2010, NGWA’s Best Suggested Practices for Aquifer Storage and Recovery has been developed through consensus of industry professionals with day-to-day experience in ASR ...

  • 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, ...

  • Drinking recycled water?

    The Australian Government National Water Commission funded a study to establish an approach to assess the quality of water treated using managed aquifer recharge. Researchers at Australia’s CSIRO Land and Water set out to determine if the en product would meet standard drinking water guidelines. At the Parafield Aquifer Storage, Transfer and Recovery research project in South Australia, the ...

  • 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 ...

  • 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 ...

  • City of Phoenix wins Groundwater Supply Award from National Ground Water Association

    The City of Phoenix, Arizona, has received an Outstanding Groundwater Project Award from the National Ground Water Association for innovation and excellence in bolstering the city’s groundwater supply. This award will be presented during the 2013 NGWA Groundwater Expo and Annual Meeting taking place in Nashville, Tennessee. Based on the City of Phoenix’s 2010 groundwater management ...

  • Turning stormwater into drinking water

    CSIRO scientists have bottled ‘Recharge’ , pure drinking water that was once stormwater. “This is an exciting demonstration of the value of stormwater and the drinking water that can be produced from it by using a combination of natural treatment processes and engineered methods,” CSIRO’s Water for a Healthy Country Flagship Urban Water Stream Leader Dr Peter Dillon said. The water was captured ...

  • 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 ...

  • 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 ...

  • World’s Largest Indirect Potable Reuse Facility Set to Expand

    The Groundwater Replenishment System (GWRS), located in Orange County, California, USA, provides purified recycled water for aquifer recharge and for injection into area aquifers to prevent seawater intrusion. The GWRS is a joint project between the Orange County Water District (OCWD) and the Orange County Sanitation District (OCSD). It is the largest indirect potable reuse project of its kind in ...

  • Water monitoring and treatment technologies gain traction as potable water resources Diminish, finds Frost & Sullivan

    Groundwater is contained in rocks that are known as aquifers. Aided by gravity, the water fills the aquifer from the bottom upwards. The lower part of the aquifer has spaces that are completely filled by water. These are termed as the 'saturated zone' of the aquifer. In the top part of the aquifer, the rock spaces contain air as well as water. This part of the aquifer is called 'unsaturated'. ...
