  • 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 ...

  • 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 ...

  • Existing and newly developed tools to assess groundwater shared at NGWA Hydrogeophysics and Deep Groundwater Conference

    The NGWA Hydrogeophysics and Deep Groundwater Conference was co-located with the Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP) March 20-21 in Denver, Colorado, where presentations shared the enhancements to existing tools and methods used to locate and assess groundwater resources as well as newly developed techniques. Several presentations focused ...

  • 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'. ...

  • EPA issues permit associated with aquifer pump test at weld county (Colo.) uranium site

    The U.S. Environmental Protection Agency has issued an injection well permit to Powertech, (USA) Inc. that will enable the company to re-inject groundwater from an aquifer pump test at the proposed Centennial uranium site in Weld County, Colorado. This Underground Injection Control (UIC) Class V permit does not allow any uranium recovery activity at the site. The permitted activity is limited ...

  • UNESCO publishes first world map of underground transboundary aquifers

    UNESCO is publishing the first-ever world map of shared aquifers to coincide with the submission to the General Assembly of the United Nations on 27 October of a draft Convention on Transboundary Aquifers. Almost 96% of the planet’s freshwater resources are to be found in underground aquifers, most of which straddle national boundaries. Despite its strategic importance, no global inventory of ...

  • Studies reveal why drinking water wells are vulnerable to contamination

    New USGS groundwater studies explain what, when, and how contaminants may reach public-supply wells. All wells are not equally vulnerable to contamination because of differences in three factors: the general chemistry of the aquifer, groundwater age, and direct paths within aquifer systems that allow water and contaminants to reach a well. More than 100 million people in the United States receive ...

  • 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 ...

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

    The University of California, Irvine (UCI) recently released two studies (here and here) using data from NASA’s Gravity Recovery and Climate Experiment (GRACE) satellites showing that the earth’s biggest groundwater basins are being ...

  • 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 ...

  • Too soon to tap Namibia`s groundwater find, experts say

    The extraction of the much needed water from a large underground aquifer in northern Namibia may need to wait for further studies, officials have warned at a water investment conference. The aquifer, discovered in July, may contain enough water to sustain about one million people living in the area for 400 years at ...

  • 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. ...

  • 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 ...

  • Nitrate concentrations of groundwater increasing in many areas of US

    Nitrate is the most common chemical contaminant in the world’s ground water, including in aquifers used for drinking-water supply. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency (USEPA) because of concerns related to infant health and possible cancer risks. Use of man-made synthetic fertilizers has steadily increased since World War II, ...

  • AUS$876,000 to help protect New South Wales groundwater quality

    Minister for Climate Change and Water, Senator Penny Wong, today announced $876,000 in funding to improve management of groundwater quality in highly-developed aquifers in New South Wales. Senator Wong made the announcement during a visit to Dubbo on the second day of a three-day tour of the northern Murray-Darling Basin. “As a result of drought and climate change, surface water in some parts of ...

  • 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 ...

  • USGS Releases Results of Gem County Groundwater Quality Study

    The entire population of southwestern Idaho’s Gem County depends on aquifers for its drinking water. The water in those aquifers is of generally good quality according to a U.S. Geological Survey report released today. The study was prompted by concerns that rapidly growing population and changes in land use, including potential ...

  • NGWA grants Groundwater Supply Award for Baton Rouge project

    Layne Christensen Co. and Owen and White Consulting Engineers Inc. have received an Outstanding Groundwater Project Award from the National Ground Water Association for outstanding engineering and innovation in supplying groundwater. This award will be presented during the 2015 Groundwater Expo taking place in Las Vegas, Nevada, December 15-17. Layne Christensen of Bloomington, Indiana, and Owen ...

  • California pledges changes in protecting underground water

    California has proposed closing by October up to 140 oil-field wells that state regulators had allowed to inject into federally protected drinking water aquifers, state officials said. The deadline is part of a broad plan the state sent the U.S. Environmental Protection Agency last week for bringing state regulation of oil and gas operations back into compliance with federal safe-drinking water ...

  • 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 ...
