  • 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 ...

  • 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 ...

  • 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 ...

  • EPA Designates Mahomet Aquifer as `Sole Source` of Drinking Water in East-Central Illinois

    The U.S. Environmental Protection Agency today announced a decision to designate a portion of the Mahomet Aquifer system as a sole source aquifer. More than half of the population in east-central Illinois relies on the Mahomet Aquifer system as a source of drinking water. The Safe Drinking Water Act gives EPA authority to designate all or part of an aquifer as a "sole source" if contamination of ...

  • 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 ...

  • U.S. EPA Seeks Public Comment on Mahomet Aquifer Designation

    The U.S. Environmental Protection Agency today proposed approval of a petition to designate a portion of the Mahomet Aquifer system in east-central Illinois as a sole source aquifer. EPA’s public comment period on the proposed designation begins March 13 and closes June 12, 2014. The Safe Drinking Water Act gives EPA authority to designate an aquifer as a sole or principal source of ...

  • 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 ...

  • Seismoelectric Groundwater Location Equipment

    Well water location. Aquifer depth, yield and thickness reported before drilling a water well. The GF6 seismoelectric technology is used for groundwater surveys {aquifer depth & yield} before drilling a water well. GF6 equipment sales and training are available world wide. Most people go straight to having a water well drilled before investigating where the aquifer is (or) if there is a good ...

  • 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: A third of global groundwater basins are overstressed

    Satellite data show people are overdrawing water from some of the world's largest groundwater basins. Researchers from the University of California, Irvine say it's unclear how much water is left in the most overburdened aquifers. The problem is expected to worsen with climate change and population growth. Using measurements taken by NASA's twin Grace satellites, scientists found the most ...

    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 ...

  • 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 ...

  • Keynote speaker announced for the NGWA Conference on Hydrogeophysics and Deep Groundwater

    Andrea Croskrey, PG, from the Texas Water Development Board will give the keynote presentation, "Mapping Brackish Aquifers: Future Water Resources," at the  NGWA Conference on Hydrogeophysics and Deep Groundwater taking place March 20-21, 2017 in Denver, Colorado.  Croskrey has been mapping brackish aquifers in Texas as a member of the Brackish Resources Aquifer ...

  • Satellite measurement of permanent loss to California groundwater source

    Researchers used satellite data to measure water volume changes due to groundwater variation in the aquifer, to show California’s Central Valley aquifer, the major source of groundwater in the region, suffered permanent loss of capacity during the drought experienced in the area from 2012 to 2015. California’s Central Valley aquifer, the major source of groundwater in the region, ...

  • Wind power helps Texas town desalinate groundwater

    The first project in the United States to use wind power to desalinate drinking water for an inland municipality rather than a coastal town has just received a $500,000 grant from the Texas state Office of Rural Community Affairs, ORCA. The $1.075 million pilot project utilizing wind power to desalinate brackish groundwater in West Texas will be located in the small city of Seminole in Gaines ...
