  • 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 ...

  • NGWREF grant funds study of potential groundwater contamination from hydraulic fracturing

    The National Ground Water Research and Educational Foundation has awarded SUNY Polytechnic Institute in Utica, New York, a $6,550 research grant to use probabilistic risk assessment and fault tree analysis (FTA) to evaluate potential groundwater degradation from hydraulic fracturing. “The public and policymakers have been concerned with the potential of hydraulic fracturing impacting our ...

  • Groundwater Modelling Software for the Environment Agency

    The Environment Agency has recently renewed its contract for groundwater modelling software for up to a further 3 years. The Groundwater Vistas and Aquifer software is supplied by ESI, the UK's leading independent soil and groundwater consultancy. ...

  • 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 ...

  • Successful field-trial remediation of 1,2-DCA and VC contaminated groundwater in Northern Italy

    The Adventus Group, an international remediation biotechnology enterprise for treatment of contaminated soil, sediment and groundwater environments, is proud to announce that laboratory and field tests recently conducted in Italy resulted in its patented EHC® In Situ Chemical Reduction (ISCR) biotechnology being selected over RegenOx® (Regenesis) In Situ Chemical Oxidation (ISCO) for its ability ...


  • Groundwater movement and contaminant transport in the Earth’s subsurface are the focus of two 2017 Darcy lectures

    Quantifying water movement and contaminant transport in the Earth’s subsurface are the critical issues addressed during presentations offered through the 2017 Henry Darcy Distinguished Lecture Series in Groundwater Science. Earth’s subsurface is part of the “critical zone” — the layer of the planet from the tops of the trees to the bottom of groundwater. This zone is ...

  • Identifying areas at risk for arsenic contamination

    The contamination of groundwater with arsenic poses a risk to the health of millions of people, especially in the densely populated river deltas of Southeast Asia. To date, no method has been available for identifying high-risk areas without conducting costly sampling campaigns. Now, Eawag has developed a model that allows vulnerable areas to be pinpointed using existing data on geology and soil ...

  • 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 ...

  • 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. ...

  • Announcing the Solinst Symposium on groundwater monitoring for the 21st century

    Design is a traditional task common to all engineering fields although most engineers do not have to deal with the heterogeneous properties of materials as is the case in site remediation, mining, geotechnical engineering, etc. A structural engineer can specify properties of steel or reinforced concrete and an electronics engineer can specify the physical properties of transistors, capacitors, ...

  • Hot microbes cause groundwater cleanup rethink

    While investigating ways of cleaning up groundwater contamination, scientists examined how microbes break down contaminants under the soil’s surface and found that subsurface temperatures associated with microbial degradation can become too hot for the microbes to grow and consume the groundwater contaminants. This can slow down the clean up of the groundwater and even continue the spread of ...

  • Natural sediment may shield groundwater from arsenic

    Contamination of deep groundwater with arsenic from shallower sources may not be as serious as feared — if pumping deep water is limited to domestic use, a study has found. Exposure to arsenic-contaminated groundwater has been linked to almost one in every five deaths in Bangladesh, ...

  • Infographic Highlights Importance of Groundwater Remediation in US

    With roughly 40 percent of the U.S. population consuming groundwater as drinking water, keeping groundwater free of contaminates is crucial. Groundwater remediation is the process of removing pollution from our water supplies and fresh drinking water. The process of cleaning up the more than 100,000 U.S. sites that have contaminated groundwater is projected to be extremely ...

  • Fear at the tap: Uranium contaminates water in the West

    In a trailer park tucked among irrigated orchards that help make California's San Joaquin Valley the richest farm region in the world, 16-year-old Giselle Alvarez, one of the few English-speakers in the community of farmworkers, puzzles over the notices posted on front doors: There's a danger in their drinking water. Uranium, the notices warn, tests at a level considered unsafe by federal and ...

  • Abanaki Corporation Releases DNAPL Groundwater Remediation System

    Abanaki Corporation is pleased to announce a DNAPL Groundwater Remediation System designed to remove high viscosity oils such as creosote from groundwater. These systems are used to remove oil contamination from existing monitoring wells. DNAPLs such as creosote tend to sink to the bottom of a well and require a specially designed system to ensure the oil is removed. Stabilizer bars are installed ...
