  • Soil and Ground Water Remediation Case Study

    On this State Funded Clean-Up project, Global was the project engineer and was responsible for the design of an air sparging/soil vapor extraction remediation system. The system included five soil vapor extraction wells and twelve sparging wells that operated on a rotating schedule. One of the soil vapor extraction wells and nine of the sparging wells were installed as horizontal wells beneath ...

  • Soil Attenuation Model for Derivation of Risk-Based Soil Remediation Standards

    Untitled Document Overview of Soil Attenuation Model (SAM) Under a risk-based corrective action (RBCA) process, soils and groundwater impacted by a chemical release are ...


  • Analytical model for uni–directional flow passive soil vapour extraction system

    An analytical one–dimensional model has been developed to examine the uni–directional barometric pumping in passive Soil Vapour Extraction (SVE) system. The model is applicable to a special case in which a radial flow field is insignificant. The system considered contains two unsaturated zone layers, an upper contaminated low permeability layer and a lower high permeability layer contains a well ...

  • Cryogenic Treatment Unit (TU-51) for Recovery of VOCs for Soil Remediation

    A Cryogenic Treatment Unit or TU-51 was developed to apply a cryogenic air treatment process to recover persistent vapor phase volatile organic compounds (VPVOC) having extremely low boiling points. These would include explosive compounds present in the vapor stream. The portable TU-51VPVOC (OEM) operates the following process: vapors are recovered from geologic units via SVE, often from a ...

  • Multifunctional Well Implemented for In Situ Remediation of Hydrocarbon Contaminations in Soil and Groundwater

    Abstract A recently developed Multifunctional Well has been implemented for the remediation of subsurface contamination caused by hydrocarbon spills. Four different remediation processes can be operated within the same well. At optimal efficiency of each remediation process, successive treatment of the capillary fringes, the vadose zone, and the aquifer can be accomplished. Each treatment ...


  • Soil Fracturing

    Introduction Fracturing is an enhancement technology designed to increase the efficiency of other in situ technologies in difficult soil conditions. The fracturing extends and enlarges existing fissures and introduces new fractures, primarily in the horizontal direction. When fracturing has been completed, the formation is then subjected to vapor extraction, either by applying a vacuum to all ...

  • Innovations in the Remediation of Contaminated Sites

      Discussion of the EPA publication completed North American Innovative Technology Demonstration Projects; share the information from this new document which is now available in an online. Mention some of the ongoing and completed field demonstrations of innovative remediation technologies sponsored by EPA and other government agencies such as DOD, NPS, USFS, and BIA. The remediation ...


  • 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 ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • The Environmental Liability Directive - Extending Nature Protection in Europe

    Abstract: With regard to nature protection through environmental liability, recent developments in Europe are most interesting. After the EC had already established a coherent species and habitat protection regime with the Birds Directive and the Habitats Directive in 1979/1992- which alone is remarkable because it covers areas of protection not only within national borders but throughout Europe ...


  • Assessment and Reporting on Soil Erosion

    Untitled Document This report presents the results of a peer review of work on soil erosion carried out by the EEA up until 2001. It also summarises the conclusions of an expert ...

  • In-situ Thermal Remediation Under an Apartment Building

    This paper presents the implementation and results of ET-DSP, an in-situ electrical soil heating technology, in combination with high vacuum dual phase extraction, to achieve the removal of vapour pressure sensitive BTEX compounds from under an occupied residential apartment building. Operating within several engineering, environmental, and safety constraints, a design was developed in order to ...

  • The direct and indirect impacts of EU policies on land

    The 2011 Roadmap to a resource efficient Europe states, in its milestone of actions to address land as a resource, that 'By 2020, EU policies take into account their direct and indirect impact on land use in the EU and globally …' (EC, 2011d). This report presents a methodology for the assessment of European Union (EU) policies in terms of their land-related implications in Europe and ...

  • Hired metals analyser ensures remediation success

    Cognition Land and Water Ltd, a UK based remediation specialist, has hired a portable XRF metals analyser to improve the speed of remediation work at a project in London’s Kentish Town. The project had a major impact on local residents so timescales were extremely tight but Cognition’s Charlie Jarvis says “It would not have been possible to meet the deadline without the use of ...

  • Significant Benefits of Augmenting an Extractive Remedial System with RegenOx™

    Recently, in the United Kingdom, a combined strategy was implemented to synergistically increase the treatment rate and efficiency of subsurface remediation while also reaching an inflexible remedial deadline cost-effectively. Central to this was the novel exploitation of a feature of RegenOx that was initially designed for an alternative purpose. The remedial strategy is now being widely used on ...

  • Extensive remediation of superfund site - case study

    The 80 acre site, formerly a minerals processing facility, was operated primarily to recover lithium and other rare-earth minerals from ores. Raw ores were imported to the site for processing. During one phase of its operations, the facility also processed uranium ores for the government. The site was listed as by the U.S. Environmental Protection Agency (EPA) as a Comprehensive Environmental ...

  • Case study - Pemaco superfund site remediation

    OVERVIEW Pemaco was formerly a chemical facility located in a light industrial and residential area of Maywood, CA, adjacent to the Los Angeles River. No one knows how long hazardous substances had been leaking into the ground but the operations date back to the 1940's.  Up until closure of the facility in 1991, chlorinated solvents, aromatic solvents, and flammable liquids had ...

  • Air emissions impact measurements at a perchloroethene remediation site

    As part of an U.S. EPA time critical removal action, an air monitoring system was established to measure real-time impacts of perchloroethene (PCE) on the surrounding areas. The soils and groundwater beneath the site (located in West Fargo, North Dakota) were treated using in situ heating of soil and groundwater, with the produced vapors collected using conventional vapor extraction. In order ...

  • Green remediation best management practices: site investigation

    Overview The need for site investigation is common to cleanups under any regulatory program. An investigation can occur at all points in the cleanup process, from initial site assessment through waste site closeout. A site investigation generally is undertaken to: Confirm the presence or absence of specific contaminants Delineate the nature and extent of environmental contamination ...

  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...
