  • Apparatus for In-Situ Remediation Using Aclosed Delivery System

    ABSTRACT: In the ever-emerging field of in-situ remediation many strides are being taken to improve the efficacy of degradation. Countless hours and unparalleled research is constantly being performed in order to improve or replace current technologies. These technologies include in-situ chemical oxidation, anaerobic processes, bioaugmentation, zero valent iron, stimulation, etc. Due to the ...

  • Green remediation

    The US Environmental Protection Agency’s (EPA) strategic plan calls for increased research and application of sustainable systems that promote environmental stewardship, reduce greenhouse gas (GHG) emissions, and improve energy efficiency. One area of this research is green remediation. Green remediation is a relatively new approach to environmental cleanup; expanded from the traditional ...


  • Sustainable remediation

    The term remediation refers to procedures implemented to eliminate contaminants and toxic waste from polluted landfills, water bodies and other places to promote environmental health and safety. Since its inception in the 1970s, remediation itself has evolved into a full-fledged industry. Organizations engaged in environmental construction activities typically execute remediation projects. In ...

  • 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 ...

  • Case study - Petroleum remediation systems

    Overview A major oil company was looking for a way to stay ahead of EPA regulations for soil vapor extraction of BTEX and the subsequent treatment of these gases. They were looking for one company that could offer competitive pricing, local support service, and the application expertise to provide 50 remediation units throughout the ...

  • Groundwater remediation using simulation-optimisation approach: A review

    Optimal design of a remediation system has been an active and important area of research since the past several years due to its potential to reduce the remediation cost substantially. The paper presents the state-of-the-art for application of simulation-optimisation approach to design an optimal groundwater remediation system. In the simulation-optimisation approach, the researchers have used ...

  • Horizontal Directional Drilling - A Green and Sustainable Remediation Remedy

    Interest in using sustainable practices and technologies for environmental cleanup has increased notably within the past few years. The US EPA and many states have published recommended practices to reduce the environmental footprint of cleanup operations, and many consultants and contractors are attempting to “go green” in contaminated site remediation. It makes sense to conserve ...

  • 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 ...

  • Stevens Systems Enhances Ground Water Remediation Effectiveness

    The Stevens Hydra Probe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The need for clean, healthy rivers, lakes and streams has stimulated research to develop ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Mine remediation case study

    Bartow, Florida GeoView, Inc. performed a geophysical investigation across a 200 acre site in Polk County, Florida. It had been reported that clay slimes from former mining operations had been deposited on the site. The purpose of the investigation was to help determine the horizontal and vertical extent of the clay slimes. Due to the large size of the site and limited budget, 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 ...

  • 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 ...
