  • 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 ...

  • Contaminants in US groundwater

    According to a new study by the USGS, more than 20% of untreated water samples from 932 public wells across the US contained at least one contaminant at levels of potential health concern. About one-third of the US population receive their drinking water from such a system. The USGS study (Contaminants in Groundwater used for ...

An electrical resistance heating system partially funded by the ...

  • US: Groundwater atlas

    The US Geological Survey series of publications “The Groundwater Atlas of the United States” describes the, location, extent and geological and hydrological characteristics of the nation’s important aquifers and is available online and in various print formats and scales. These have been produced over recent years as described in a useful summary fact sheet. Find out ...


  • 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. ...

  • 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 ...

  • 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. ...

  • Kenya homes in on emergency groundwater supplies

    A project that will map groundwater resources in part of the drought-prone Horn of Africa region was launched in Nairobi, Kenya, last week (22 May). It will use remote sensing technology to explore underground ...

  • 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 ...

  • National Groundwater Awareness Week time for groundwater professionals to shine

    Groundwater industry professionals, the world’s experts on this natural resource, have a unique opportunity to educate the public about groundwater and water well stewardship during National Groundwater Awareness Week, March 10-16, 2013. This year represents the 15th edition of this event sponsored by the National Ground Water Association, said NGWA Public Awareness Director Cliff ...

  • Arsenic Illegally Released into California’s Groundwater

    The Environmental Protection Agency (EPA) has fined a natural-gas fired power plant $13,500 for improper management of hazardous waste. According to the EPA, the plant, located in Yuba City, California, generated arsenic from the treatment of wastewater and failed to minimize releases of hazardous waste to the environment. Arsenic occurs naturally in the local groundwater, which the plant uses in ...

  • 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 ...

  • Strategy to assess the US`s groundwater availability

    Scientists proposed a strategy to study the Nation's ground-water supply as part of the Federal government's effort to help address the Nation's increasing competition for water. Declines in ground-water levels have led to concerns about the future availability of ground water, which provides half the country's drinking water and is essential to the vitality of agriculture and industry, as well ...

  • Groundwater monitoring: what’s winter field work like?

    Although the stimulation phase of the Newberry EGS Demonstration has come to a close, field work continues throughout the winter months on the volcano (brrr!). We’re currently collecting and analyzing groundwater samples in order to monitor any changes in the local groundwater system.
