  • Monitoring Gas Emissions from Volcanoes to Predict Volcanic Activity

    To understand and predict the behaviour of volcanoes an increasing number of scientists are combining geological monitoring and geochemical models. By measuring and monitoring the prevalence of gases like CO2, scientists hope to be able to better predict the likelihood of volcanic eruptions. In 2010 Iceland’s Eyjafjallajökull volcano erupted, releasing 250 million ...

  • Tunnelling in Chalk: Groundwater monitoring and risk assessment

    Morgan Est is constructing a tunnel to carry high voltage electricity cables between two electrical substations.  The tunnel will mostly be excavated in Chalk, with some excavation occurring in the Thanet Sands. ESI was appointed as Morgan Est’s environmental consultant for the project and has managed liaison between Morgan Est, regulators and other stakeholders over the last four ...

  • Research considerations for more effective groundwater monitoring

    Since numerous pathogens occur in feces, water is monitored for fecal contamination using indicator organisms rather than individual pathogens. Although this approach is supported by health effects data in recreational waters, it is questionable when used for drinking water. Most outbreaks in groundwater occur in systems that have not violated the US EPA's maximum contaminant limit (MCL) ...

  • Monitoring groundwater resources for Municipalities - Case Study

    Background The City of Tucson is located in the Sonoran Desert in southwest United States (U.S.), approximately 100 km north of the Mexico-U.S. border. Tucson Water operates more than 215 groundwater wells, covering more than 300 square miles, providing more than 37 billion gallons (140 million m3) of potable water to its 730,000 inhabitants each year. The region receives only 12 inches of ...

  • Optimal groundwater contamination monitoring using pumping wells

    This study presents a new method for selecting monitoring wells for optimal evaluation of groundwater quality. The basic approach of this work is motivated by difficulties in interpolating groundwater quality from information collected for only few sampled wells. The well selection relies on other existing data relevant to contaminant distribution in the sampling domain, e.g. predictions of ...

  • Case study - Ireland Groundwater Monitoring Program

    To fulfill the EU Water Framework Directive (WFD) requirements, a groundwater monitoring program was established by the Environmental Protection Agency of Ireland. This program focuses on providing information to assess the environmental status of surface and groundwater bodies. Read about the program and the example installation in the Bog of the Ring. Technology Used: OTT Orpheus Mini, OTT ...

  • The Influence of an Integrated Remedial System on Groundwater Hydrology

    ABSTRACT This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored natural attenuation ...

  • Groundwater pump & treat and SIPEX skimmimg system

    GRS has supplied and installed a system for the abstraction of free-phase floating creosote contamination. The system comprises frequency controlled submersible pumps for precise hydraulic control and our motorised interface tracking system which, due to large local water table fluctuations, was modified to provide a product/water interface tracking range of 5m.Abstracted groundwater is pumped to ...


  • Groundwater monitoring and assessment with ESdat environmental data management software and its use in groundwater remediation plans

    Groundwater investigations, contaminated/industrial sites, landfill and regulatory compliance are all ideal areas for environmental consultants and site managers, specializing in groundwater monitoring and assessment, to use environmental data management software. A successful groundwater ...

  • GE Leakwise Application Notes: Leak Detection by Groundwater Monitoring

    Risks of Groundwater Contamination Hydrocarbon leakage, from Underground Storage Tanks (USTs) and from the bottoms of above ground tanks, can seep into the groundwater, where it forms a floating oil sheen, or a thick oil layer. This layer, if left undetected, ...

  • Groundwater Remediation System Cleans Up Oil Spill

    A customer in TX was recently in some hot water with the local municipal water department. Due to excessive rains near the coast of Texas, the water levels have been higher than usual. The company fills storage tanks with diesel at its facility. However one day the tanks were overfilled and instead of going into the ground, they diesel dispersed out via the high rain water and into the local ...

  • Case study - Groundwater monitoring around hydraulic fracturing sites in Colorado

    Hydraulic fracturing or ‘Fracking’ has become more prevalent and controversial in the US in recent years. More than 90 percent of new wells in the US are completed using this method. While it is endorsed by some as a game-changer that promises an increase in the nation’s economy due to energy independence, job creation, and lower energy prices; others are calling for a temporary ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

  • Case study - Westbay System delivered cost effective groundwater monitoring in mountainous region

    Multilevel well network provided high-density data at a reduced cost CHALLENGE After installing a number of traditional  monitoring wells at the site, it became  clear to the project scientists that more  and better data would be necessary  to properly characterize the complex  groundwater flow system. SOLUTION ...


  • Soil and groundwater assessment, Northern England

    Project Remediation Strategies were appointed to assist in the identification of a hydrocarbon contamination source that had resulted in significant vapours within a residential property. Further works to asses the nature and extent of soil contamination were also commissioned, together with detailed vapour risk assessments and subsequent vapour remediation works. ...
