  • In Deep Water

    In spring of 2013 the Rockmore ROK 500DH hammer was able to get a water-well driller in Washington, US out of a tight spot when a competitors hammer failed to reach the water table for the well he was drilling. The driller was using a hammer that was getting no penetration rate at 1,300 ft. Looking for help, he reached out to a Rockmore distributor in his area who was able to supply him with the ...

  • Inequitable allocation of deep community wells for reducing arsenic exposure in Bangladesh

    Community wells that extend deeper than most private wells are crucial for reducing exposure to groundwater arsenic (As) in rural Bangladesh. This study evaluates the impact on access to safe drinking water of 915 such intermediate (90–150 m) and deep (>150 m) wells across a 180 km2 area where a total of 48,790 tubewells were tested with field kits in 2012–13. Half the shallow private wells ...

  • A method for reducing purge volumes in deep monitoring wells: a purging experiment.

    Regulatory agencies often require three well casing volumes or more be purged prior to collection of groundwater samples for chemical analysis. Costs are high for testing and disposing of potentially hazardous purge water; therefore, efforts must be made to minimize waste-water volume while obtaining representative groundwater samples. Lockheed sponsored a purge experiment on two deep monitor ...

  • Griffin Dewatering pumps 15 million gallons of water from flood control project with 75 foot deep wells

    On April 29 2011, Houston-based Griffin Dewatering Corp. began pumping 15 million gallons of water from the site. It also used 42 10-in.-dia, 75-ft-deep wells outside the dam perimeter to lower the groundwater table and relieve external hydraulic pressure. Griffin is working on several Corps projects in New Orleans, but Michael Lippard, Griffin senior project manager, says Seabrook is ...

  • Portland, Or - Deep, DNAPL remediation

    In 1999, the senior managers of Thermal Remediation Services, Inc (TRS) while working for a former employer, as a subcontractor to AMEC, provided Electrical Resistance Heating (ERH) for VOC-impacted groundwater at a commercial site in Portland, Oregon. The remediation was conducted under the Oregon Department of Environmental Quality (DEQ) Voluntary Cleanup Program. The remedial action objective ...

  • Case Study - Multilevel well system improved understanding of groundwater conditions in deep aquifers

    Westbay System delivered detailed data in less time and at a reduced cost CHALLENGE Characterizing the plume in a shallow  aquifer is simple, but investigating deeper  aquifers poses several challenges. SOLUTION MACTEC evaluated various monitoring  technologies and determined that  Westbay System modular ...


  • Diving with Deep Trekker Summer of 2016

    At the beginning of the summer, we acquired our new research vessel appropriately named “Deep Trekker”. Over the past four months, we have spent many hours aboard the boat exploring shipwrecks and the waters of Lake Huron and Lake Erie. During several trips to Georgian Bay is where most of our work was done as well as where some awesome photos were taken of our adventures. We wanted ...

  • Deep sea mining — a dangerous experiment

    Pacific governments should not approve deep-sea mining until more is known about its likely impact, says conservation biologist Mellie Samson Jr. Deep sea mining (DSM) is the new frontier in extractive mining. For the companies involved, as well as the governments that own the mining rights, it offers substantial profits. However DSM is still experimental in nature, with ...

  • Deep sea mining: exploration is inevitable

    Despite concern over adverse impacts, deep marine mineral exploration is set to become a global industry, says geologist Chris Yeats. Global demand for metals continues to grow, fuelled largely by increasing populations and the industrialisation and urbanisation of China and India. To meet this demand, the international ...

  • Utilisation of deep geothermal energy for heating purposes

    The Hot-Dry-Rock-(HDR) technology allows a location-independent utilisation of geothermal heat, because aquifers in deep formations, i.e. layers filled with water, are not necessary. The flow paths for the circulating water in a depth of 4 km are created by hydraulic fracturing of existing gaps. Due to the fact that this new technology is quite cost-intensive, high annual load duration of the ...

  • Portable Carpet Cleaners for Deep Cleaning Carpets in Hotels

    As soon as people walk into a hotel, the first thing they generally notice is how well-maintained the place is. They especially take note of factors like if the furniture is free of dust, if the indoor plants look well-attended to, if the floors are squeaky clean, if the place smells fresh, and if the carpets are clean and stain-free. Talking of carpets, it is one piece of décor that ...

  • Hydrochemical investigation of water from the Pleistocene wells and springs, Jericho area, Palestine

    Rising salinity levels is one of the significant signs of water-quality degradation in groundwater. The alluvial Pleistocene wells in the Jericho area, Palestine show high salinity and a high susceptibility to contamination. Future exploitation and management of the water resources under these conditions will require an in-depth understanding of the sources and mechanisms of contamination. The ...

  • Effect of soil-use on deep groundwater quality in Southern Chile

    This study evaluated the effects of farming activities on the quality of deep well water in Southern Chile. In this area, the use of fertilisers is becoming more widespread and the accumulation and poor management of cattle slurry and silage sub-products increases the risk of contamination. The study was carried out in the province of Osorno, where rainfall occurs all year round (maximum in ...
