  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • Horizontal Remediation Wells - Case Study

    Why wait 30 year…when HRWs are here today! After 30 years of remediation, the responsible party became frustrated with the limitations of vertical wells and the inability of methods used to achieve cleanup goals.  Seeking site closure, the soon to be client, turned to Directional Technologies and Horizontal Remediation Wells (HRWs) to break the stalemate.  The HRWs were ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

    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 ...


  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Residential Heat Oil Remediation using ORC in Soil and Groundwater

    BackgroundIn a coastal Massachusetts community, Fuss & O’Neill, Inc. performed investigation and remediation activities to address the release of No. 2 heating oil to soil and groundwater at a residential property. Therelease occurred at a home heating system installed in the crawl space beneath the residence. Soil at the site consists of two to five feet of silty sand and gravel fill ...

  • 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 ...

  • 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 ...

  • Accelerated remediation of chlorinated solvents using a horizontal ZVI PRB in combination with ISCR for enhanced Anaerobic remediation

    Description: Industrial Site in Apeldoorn, Netherlands Consultant and Contractor: NTP Enschede Approach: Severe soil and shallow groundwater contamination by metals and chlorinated solvents (cVOCs) was detected at the site.
