  • LNAPL remediation using electrical resistance heating

    Abstract An Electrical Resistance Heating (ERH) pilot test was conducted in the fall of 1998 to determine the effectiveness of using ERH in combination with soil vapor extraction (SVE) for the remediation of benzene and light nonaqueous-phase liquids (LNAPL) at an island location on a river in the Midwest. Hydrocarbon-stained soils were discovered on an island in Ohio in May 1993 during the ...

  • Key Elements of a Successful Horizontal Remediation System

    Environmental remediation professionals around the country (and internationally) are rapidly learning that Horizontal Remediation Systems are an essential “tool in their remediation toolbox”. When designed and executed by experienced horizontal environmental drilling experts, Horizontal Remediation Systems can be extremely effective at achieving rapid site closure compared to vertical ...

  • Using sediment cores to establish targets for the remediation of aquatic environments

    When assigning site-specific restoration targets for deteriorating aquatic systems, it is necessary to have an understanding of the undisturbed or background state of the system. However, the site-specific characteristics of aquatic systems prior to disturbance are mostly unknown, due to the lack of historical water and sediment quality data. This study aims to introduce a method for filling ...

  • Use of vermiculture technology for waste management and environmental remediation in Argentina

    Throughout the world, there have been increasing interests in the recycling of wastes for sustainable development. This especially applies for organic materials of municipal and agro-industrial origin. Recycling initiatives in Argentina are still incipient. In the last years, the use of earthworms for stabilising organic wastes has been evaluated. In this paper, the authors compile the research ...

  • Horizontal Remediation Wells used in order to preserve military security

    Project Description: Remediate a plume of trichloroethylene (TCE) under multiple military buildings by air sparging (AS) and soil vapor extraction (SVE). There are two target zones: the shallow zone is approximately 70' below grounds surface (bgs) and 20' below this is the deep zone. The plume was located under multiple buildings comprising an area of approximately 150,000 SF. Scope of Work: ...

  • Aerobics to the Rescue - Using Compatible Technologies to Improve Groundwater Remediation

    Background Increased opportunities for contaminated property redevelopment have propelled property owners to evaluate options for accelerating site remediation. In some cases a containment technology may have been implemented to mitigate the off-property migration of contamination as the most ...

  • Soil and groundwater remediation

    At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

  • 3-in-1 Flame-Ox High BTU Thermal Oxidizer - Case Study

    Environmental Issues Controlling the off-gas from a remediation project, where high concentrations of petroleum hydrocarbons are present, can be a difficult if not dangerous process when utilizing internal combustion engines and conventional oxidation technology. In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes ...

  • Case study - Successful remediation of MTBE-impacted groundwater using in situ

    Description Initially an SVE/bioventing system was operated for 16 months, removing over 20,800 pounds of gasoline, leaving groundwater concentrations of TPHg and benzene of 60 and 0.37 ppb, respectively.  The highest MTBE concentration in September 2001 was 5,400 ppb at a monitoring well just downgradient of the former USTs, with a total estimated area above 500 ppb of over 12,000 ...

  • New Jersey Uses GIS, EQuIS to Collect Site Remediation Data

    Using GIS To Manage Remediation Data GIS holds great potential as a tool for managing environmental site remediation data. While using GIS to locate Superfund sites is commonplace, GIS has played only a minor role in the review and analysis of chemical data gathered during an investigation or monitoring activity. There are a number of reasons why GIS has not become commonplace in the ...

  • 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 ...

  • The Effectiveness of Using Automated Belt Oil Skimmers as a Method of Well Remediation

     ABSTRACT In many sites across the country, groundwater has been contaminated by petroleum products due to leaky underground tanks or past spills. If the leak has gone unnoticed, a considerable amount of product could exist in an aquifer (underground water reservoir), and may be trapped in the surrounding rock. Remediation can take months or years to complete and is frequently labor ...
