  • 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 ...

  • Groundwater contaminant assessment and remediation subjects of NGWA courses in Maryland

    Groundwater industry professionals can increase their remediation technology knowledge in two different National Ground Water Association short courses taking place September 2008 in Baltimore, Maryland. “Understanding Migration, Assessment, and Remediation of Non-Aqueous Phase Liquids,” September 23-25, provides hydrogeologists, regulators, and anyone dealing with ground water contamination ...

  • New USGS assessment provides fresh insights into nation’s brackish groundwater inventory

    A new nationwide assessment by the U.S. Geological Survey suggests that the nation’s brackish groundwater could help stretch limited freshwater suplies. This study, the first of its kind in more than 50 years, found that the amount of brackish groundwater underlying the country is more than 800 times the amount ...

  • 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 ...

  • Scientists Assess 100 years of Los Angeles Groundwater Replenishment

    A new study offers the most sophisticated analyses to date on how Los Angeles-area groundwater supplies are replenished. The analyses provide water managers with a clearer understanding of the sources and amount of available groundwater in the region – information that is important for planning and management of the vital resource. A new study offers the most sophisticated analyses to ...

  • Simple solutions for assessing unconventional gas sites focus of paper in Groundwater

    A recently published scientific paper offers simple analytic solutions for providing preliminary assessments and insights of unconventional gas sites that are not site-specific. The article was published in National Ground Water Association’s flagship technical journal, Groundwater®. While there are sophisticated numerical modeling studies offering possible predictions 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 ...


  • Groundwater pollution in Europe: an overview

    An overview of groundwater contaminants in Europe is provided by a recent study, which calls for more integrated monitoring using a range of indicators. Groundwater contamination presents serious health and environmental concerns. A number of Directives, including the Water Framework, Groundwater, Nitrates, Industrial Emissions and Landfill Directives, together aim to protect groundwater from ...

  • How vulnerable is our groundwater?

    When water travels through soil and bedrock to the water table, it carries minerals, nutrients or chemicals from the surface with it. Environmental research is increasingly concerned with preferential flow, or the movement of water through pores and cracks at a faster rate and bypassing most of the surrounding material, either soil or fractured rock. A special section on preferential flow ...

  • New guidance for groundwater site characterization

    Synopsis: Environmental practitioners are often constrained by rigorous time and monetary constraints, which can lead to the collection of limited data sets and decisions made based on an inadequate understanding of site conditions. To facilitate effective site assessments in British Columbia, the BC Ministry of Environment recently released a new guidance document, "Technical Guidance #8", for ...

  • Special issue of Groundwater Monitoring & Remediation focuses on agricultural impacts to groundwater quality

    The National Ground Water Association’s technical journal,Groundwater Monitoring & Remediation®, has published a special issue focusing on the monitoring and remediation of agricultural impacts to groundwater quality. Agricultural land use represents the largest nonpoint source threat to groundwater quality on a global scale. As a result of decades of fertilizer application and ...

  • Encouraging results in evaluating groundwater contaminants

    The widespread use of pesticides across the United States has been in practice for decades, with little knowledge of the long-term effects on the nation’s groundwater. The results of a new study show that samples taken from over 300 wells across the US have not retained a high concentration of pesticide contamination. The news is a result of a decadal long study to assess the extent of the ...

  • Determining the good status of groundwater in the EU

    Groundwater standards in Member States are to be established by the end of 2008, according to the European Union's new Groundwater Directive. Recent research has developed a new method to determine the chemical status of groundwater which is applicable across the EU. This procedure has been assessed by testing the quality of the groundwater of the Upper Rhine Valley in Germany, Switzerland and ...

  • 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  ...
