  • Case study - Reactive barrier wall project update

    Reactive Barrier Wall solves space and on-going activity problems during remediation project “Name Removed”, was contracted to install a passive reactive barrier wall in “Name Removed”. The wall was designed to remediate groundwater containing tetrachloroethylene (TCE). What made this job unique was the site location. Installation would occur in an operating commercial ...

  • Case study - Gas plant groundwater remediation

    One-pass trenching method used for a gas plant groundwater remediation project Not many environmental engineers have heard of one-pass trenching and even fewer have actually applied this cutting-edge technology to environmental control and clean-up. However, a growing number of companies are starting to use this technology, resulting in decreased cost of installation and increased system ...

  • McClellan AFB comparison of 6 no-purge groundwater samplers

    This report describes the activities and results of a field demonstration of six different diffusion and grab groundwater sampling devices at the former McClellan Air Force Base (McClellan), located in Sacramento, California. Analytical results from these samplers are compared to ‘baseline’ analytical results from samples collected using conventional (low-flow and three-casing-volume purge) ...

  • Centerbrook, Connecticut excavation; open-hole chemical oxidation case study

    A spill of 2500 gallons of fuel oil occurred at this Connecticut facility when a normally open valve was inadvertently closed during filling operations. The fuel seeped into earthen floor of the containment area and surrounded the saddle wall footings. Groundwater, present at a depth of 5 feet, stopped the downward migration of the fuel and became ...

  • In-Situ Remediation of Heavy Metals Using Sulfur-Based Treatment Technologies

    The Metal Problem Highly toxic and highly soluble metals are contained in numerous waste streams including those from power, chemical, electronics facilities, general manufacturing plants, and mining facilities. Lead, chromium, arsenic, zinc, cadmium, copper, and mercury are the most common metal contaminants found on remediation project sites (US EPA, October, 2000). Cyanide is a common ...

  • Installation of vertical barriers using deep soil mixing

    Introduction As contamination from liquid wastes and polluted groundwater continue to be a major environmental remediation topic, methods and applications for installing vertical barriers continue to evolve. The need to contain the pollutants to reduce their potential effects has broadened the scope of a vertical barrier. Greater depths than before are required as the contamination continues ...

  • Organoclay permeable reactive barrier utilized to control napl contamination case study

    Project : Bay Project - Union Pacifi c Railroad Location : Escanaba, MI Products : Bulk Organoclay, Reactive Core Mat Background: The groundwater at a former creosote wood treating site was contaminated by non-aqueous phase liquid (NAPL). The contaminated groundwater was a threat to the nearby fresh water bay when NAPL and ...

  • Installation of EHC for VOCs

    Project Installation of EHCT for Treatment of Chlorinated Volatile Organic Compounds Summary Adventus installed 1 ton of EHC® into a trench and 3 tons of EHC® into an open excavation at a site that has groundwater contaminated with a mixture of chlorinated solvents. The Challenge Two areas of contamination were targeted for ...


  • Development of the Sleeper Pit Lake

    The Sleeper open pit gold mine operated from the mid-1980s through the mid-1990s. Operations were mostly sub-water table and extensive dewatering was required to lower groundwater levels by 180 m. Dewatering flows peaked at 930 L/s, with most flow contributed from an alluvial aquifer. After completion of mining, the pit was rapidly filled with water pumped from the alluvial aquifer to reduce the ...

  • Feds propose new reg to remove leaking storage tanks from service

    With spills and leaks from storage tank systems that contain petroleum products continuing to pose significant health and environmental risks, the federal Department of the Environment proposed recently a new regulation to reduce the risk of contaminating soil and groundwater. The proposed Storage Tank Systems for Petroleum Products and Allied Petroleum Products Regulations would replace the ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • World War II Memorial, DC - Case Study

    In 2003, AdEdge Water Technologies began working closely with EarthTech, the assigned engineering firm responsible for specifying and selecting the various water treatment systems serving the new National World War II Monument in Washington, DC. Stormwater and groundwater control and treatment are essential aspects of this project given the location of the site on the Mall adjacent to the ...

  • Refinery remediation: fuel recovery and recycling

    Introduction The site is a former refinery that occupied approximately 64 acres of land in West Texas. Refinery operations produced all grades of gasoline, tractor fuels, diesel, distillate products, and fuel oils and operated between 1939 and 1954. As a result of past waste management practices, releases to soils and ultimately ground water occurred, resulting in the formation of a ...

  • Mechanisms of heavy metal removal using microorganisms as biosorbent

    Release and distribution of heavy metals through industrial wastewaters has adverse affects on the environment via contamination of surface- and ground-water resources. Biosorption of heavy metals from aqueous solutions has been proved to be very promising, offering significant advantages such as low cost, availability, profitability, ease of operation, and high efficiency, especially when ...

  • Chemical and Biological Treatability Testing of an Industrial Leachate

    Remediation efforts are ongoing at the Avtex Fibers Superfund Site in Front Royal, Virginia. As part of the future remediation of several surface impoundments used for viscose waste disposal during plant operation, it may be necessary to extract contaminated leachate and groundwater for ex-situ treatment and discharge to the Shenandoah River. This waste stream contains high concentrations of ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country.
