  • USGS Groundwater Model: New Tool for Communities in Northern and Central Arizona

    A new groundwater model of the interconnected aquifers in central and northern Arizona was released today by the U.S. Geological Survey, following a multi-year development effort that involved the Arizona Department of Water Resources and regional cooperators.  The computer model, known as the “Northern Arizona Regional Groundwater-Flow Model,” simulates how recharge from ...

  • Corporate fight lets toxics flow into Connecticut groundwater

    Connecticut officials are seeking an order against two disputing companies whose inaction and ongoing argument they allege is allowing PCB contamination to jeopardize Bridgeport Harbor and Long Island Sound. Connecticut Attorney General Richard Blumenthal and Department of Environmental Protection Commissioner Gina McCarthy said that the state has requested a temporary injunction against The ...

  • WRD`s Groundwater Monitoring Keeps Safe Water Flowing in the City of Bell

    The Water Replenishment District of Southern California's (WRD) groundwater monitoring well in the City of Bell across from the Bell Community Center, continues to ensure groundwater safety for Bell residents. In 2009, WRD worked with Congresswoman Lucille Roybal-Allard to secure over $400,000 in federal funds for this ...

  • Coordinated groundwater recharge needed

    The massive rains over California last month are not just a blessing but also a curse: a curse because the intensity of rain causes serious problems with flooding, erosion and landslides. Every watershed in California should therefore have a coordinated program to intentionally capture flood flows and recharge groundwater aquifers. Extreme weather is one reason so much reservoir storage has been ...

  • Nanoparticles decontaminate groundwater

    Since their invention a decade ago at Lehigh University, iron nanoparticles 1,000 times thinner than a human hair have demonstrated an unprecedented ability to clean contaminated groundwater. The palladium-coated particles have remediated more than 50 toxic waste sites in the US and other countries in 10 times faster than traditional pump-and-treat methods. Researchers at Lehigh University have ...

  • Tungsten groundwater contamination

    Originally thought to be non-toxic, tungsten is replacing lead in fishing weights and in ammunition for hunting and recreational shooting. However, recent studies indicate that (under certain environmental conditions) some forms of tungsten can move readily through soil and leach into groundwater. A Kansas State University scientist investigates. Tungsten is a naturally occurring metallic element ...

  • Regional groundwater modeling

    Advanced Regional Groundwater Modeling Software SoilVision Systems Ltd. is pleased to announce the addition of regional groundwater modeling capabilities to SVFlux as well as our complementary 3D products.     The Finite Element Code Advantage Finite element code allows modeling of more complex geometries and boundaries than with ...

  • 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. ...

  • 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 ...

  • 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 ...

  • Regional scale groundwater understanding

    South-central Ontario, and specifically the Oak Ridges Moraine area, has been the focus of considerable investigation relating to groundwater over the past few decades.  The importance of the collection, management and utilization of various integrated datasets (e.g. climate, streamflow, groundwater) in the development, application and refinement of conceptual and numerical groundwater flow ...

  • News, release of a new groundwater software

    VisualRflow is a completely new reactive transport software, it is as fast as Bioscreen but as powerfull as RT3D. VisualRflow is dedicated ot 2D horizontal saturated flow and transport of dissolved reactive species. It is largely oriented towards natural attenuation, but can deal with other cases. The interface is a simplified pre- and post-processor for Modflow, when flow has been calculated, ...


  • 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. ...

  • PFAS - Treatment of Groundwater on Airport Site

    The effect of the innovative solution PerfluorAd is to remove the bulk of PFAS or PFC contaminats prior to an activated carbon polishing system without breakdown components and with the result that activated carbon life is significantly extended and disposal costs reduced. Data are derived from a real field application at a European airport. We are happy to share the results. PFC ...

  • Midwest groundwater tainted with sewage and chemicals

    Raw sewage is flowing into rivers and streams across central and eastern Iowa as one after another wastewater facilities are inundated by the record floods that have swept the state during the past two weeks. Livestock manure is also part of the nasty mix, along with spilled fuel and chemicals, all heading to the flooding Mississippi River and down to the Gulf of Mexico. The U.S. Environmental ...

  • Volatile dense chemical liquids in groundwaters can produce slowly bubbling gas flow

    Despite decades of research, the cleanup of soil and groundwater contaminated by dense non-aqueous phase liquids (DNAPLs) used in numerous industrial applications remains a daunting challenge. These compounds, including degreasers, dry cleaning fluids, creosote, solvents and coal tar, when present below ground can generate hazardous concentrations for decades to centuries as they dissolve into ...

  • High quality groundwater sampling explained

    The Solinst Technical Bulletin on High Quality Groundwater Sampling explains how to obtain representative groundwater samples using Solinst Bladder Pumps, 464 Electronic Pump Control Units and our 12 Volt Compressor.
