  • Africa may struggle to extract groundwater, experts say

    Vast groundwater resources have been revealed in Africa by the first continent-wide quantitative maps. But the resources may not be easily accessible because of political and technical challenges and costs, say experts. The new groundwater maps, published last month (19 April) in Environmental Research Letters, are based on an extensive review of available maps, publications and data. They show ...

  • High quality groundwater sampling

    Representative Samples A project manager’s goal for groundwater sampling is to collect samples that are representative of actual in-situ conditions, and to maintain sample integrity by minimizing the changes in sample quality and chemistry during collection. Sampling has evolved from earlier techniques of bailing and high rate pumping, to techniques of minimal drawdown and low flow ...

  • Solar power to clean groundwater

    The US Environmental Protection Agency's Jared Blumenfeld (image), US Congressman Mike Thompson and Linda Adams, Secretary of the California Environmental Protection Agency have provided details about recent exciting energy conservation and cleanup accomplishments at the Frontier Fertilizer Superfund site in Davis, California. An electrical resistance heating system partially funded by the ...


  • Shale gas extraction linked to water contamination

    A new study suggests shale gas extraction leads to methane contamination of underground water sources and calls for thorough surveys of methane levels at extraction sites. The study presents a timely insight into a relatively under-researched area of science that will help support decisions on the future of shale gas exploration. Shale gas, or natural gas extracted from sedimentary rocks ...

  • 1,4-Dioxane Bioremediation in Groundwater Update

    The US Environmental Protection Agency (EPA) announced in late 2016 that 1,4-dioxane was included on the list of the first 10 chemicals slated to receive safety reviews under Toxic Substances Control Act (TSCA) reform. Making the TSCA “Top 10” highlights concerns over 1,4-dioxane, a probable carcinogen commonly detected in groundwater due to its widespread use as a solvent and solvent ...

  • Calculating recharge of groundwater more precisely

    An international team of researchers has demonstrated that key processes in models used for the global assessment of water resources for climate change are currently missing. This could mean climate change impact models are wrong in some parts of the world and cannot yet be used to guide water management. The study, published today [Tuesday 28 February] in the  ...

  • Helping to secure Australia`s groundwater future

    The Parliamentary Secretary for Water, the Hon. Dr Mike Kelly AM MP, has announced $2.1 million in funding for three new projects to better manage Australia's groundwater whilst launching National Water Week 2009 at Parliament House in Canberra. Dr Kelly said, “The theme for this year's National Water Week is 'Securing Our Water Future' and this is particularly appropriate when it comes to ...

  • XTO Energy, Inc. to Restore Areas Damaged by Natural Gas Extraction Activities

    The U.S. Environmental Protection Agency and the Department of Justice announced today that XTO Energy, Inc., (XTO) a subsidiary of ExxonMobil, the nation’s largest holder of natural gas reserves, will spend an estimated $3 million to restore eight sites damaged by unauthorized discharges of fill material into streams and wetlands. XTO will also implement a comprehensive plan to comply with ...

  • 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 ...

  • Fracking: leaking wells cause gas-contaminated groundwater

    Contamination of drinking water in areas close to several fracking sites in the Marcellus and Barnett Shales, USA, is caused by structural problems leading to wells leaking natural gas into aquifers, a new study suggests. The researchers measured trace amounts of chemicals, called noble gases, which formed signatures of the sources of gas contamination in over 130 samples. These findings suggest ...

  • Journal article evaluates methane sources in groundwater in Pennsylvania

    The findings of a new study in the journal Groundwater suggest that methane concentrations in Susquehanna County water wells in Pennsylvania can be explained without the migration of Marcellus shale gas due to hydraulic fracturing. “Testing of 1,701 water wells in northeastern Pennsylvania shows that methane is ubiquitous in groundwater, with higher concentrations observed in valleys vs. ...

  • Groundwater experts meet to tackle future management challenges

    The Parliamentary Secretary for Water, the Hon. Dr Mike Kelly AM MP, has opened the National Water Commission's inaugural national Groundwater Forum, which has brought together 120 of Australia's leading groundwater experts to discuss the challenges in managing the nation's groundwater and the associated reform actions agreed under the National Water Initiative. Dr Kelly said, 'Groundwater is a ...

  • Victorian Groundwater Management System Direct Input to ESdat

    The Victorian groundwater management system (GMS) is a database of groundwater related data (for example groundwater, geology or chemistry data) across Victoria that is delivered quarterly by DVD from the Department of Sustainability and Environment to registered subscribers. The delivery of data from this system is often in a format that is time-consuming to extract, filter and output as useful ...

  • Scientists develop improved groundwater forecasting model

    Scientists in India have developed a more efficient computing model to predict monthly changes in groundwater, which is depleted in many areas of developing countries because of damaged soils and poor irrigation practices. A team of scientists based in India's four southern states used the concept of an 'artificial neural network' (ANN), a computing technique that mimics the way millions of ...

  • Spanish earthquake could have been triggered by groundwater pumping

    An earthquake that killed nine people in Lorca, Spain, last year could have been triggered by groundwater being drained from the area for use in irrigation, according to scientists. The study found that the ground moved in the same places as subsidence has been occurring since the 1960s, due to the extraction of groundwater. In Europe, earthquakes are most common in southern and ...

  • EPA to hold public meeting for the aberdeen contaminated groundwater site in Aberdeen, NC

    The U.S. Environmental Protection Agency (EPA) will host a public meeting regarding the Aberdeen Contaminated Groundwater Site on Wednesday, September 07, 2011, at 6:30 to 8:30 p.m. at the Aberdeen Town Hall located at 115 North Poplar Street in Aberdeen, Moore County, NC. The EPA and the North Carolina Department of Environment and Natural Resources (NCDENR) are hosting the meeting to present ...

  • Dual density convection well used to cleanup PCE-impacted groundwater

    In just 3.5 years, we were successful in reducing PCE concentrations in groundwater from an average of 10,000 ppb to under 25 ppb using one dual density convection (DDC) well and a soil vapor extraction system in the source area. This technology involves no pump-and-treat and is extremely cost effective. For more information, please contact ...
