  • The Power of 243 Vertical Wells

    This is a comparison of a Horizontal Remediation System and a Verticle Well System at a theoretical site with an area of 388,800 ft  where with a Radius of Influence (ROI) of 20 feet, 12 Horizontal Remediation Wells, depending on plume geometry, can cover the same area as 243 vertical wells with the same ROI per ...

  • Former Manufacturing Facility Remediation- Case Study

    ERC was hired as the General Contractor to remediate a former manufacturing facility in central Ohio.  Basic geology of the site was ground surface to 4 to 6 feet bgs silts and clays followed by sand and gravel to the top of the water table at 8-12 ft bgs.  The site had Tetrachloroethene (PCE) contaminated soil in an approximately 0.33 acre area.  ERC performed the excavation and ...

  • Water Quality and Habitat Improvement at a Decommissioned Phosphate Fertilizer Facility

    As part of their long-term site restoration plan, ICI created within the former prefiltration pond a pond/wetland/upland wildlife habitat to benefit local species of birds, mammals, and plants, along with a myriad of other living creatures. The site already supported a wide range of flora and fauna, which has been enhanced by this restoration. The completed project now provides for selected areas ...

  • Restoration of Vegetation Affected By Diesel Spill

    The toxicity of diesel spill was reduced facilitating healthy growth of grass and other vegetation at the site. TPH of the soil was reduced from 65,000 ppm to less than 1000 ppm by on site application. Restoration of vegetation and reduction of toxicity of spill using AgroRemed was achieved at a cost of less than $ ...

  • Rapid Reduction of VOCs Results in Site Closure

    Summary Subsurface investigations at a dry cleaning facility revealed elevated levels of PCE and other regulated daughter products. A remediation technology was needed that could cost-effectively reduce the contaminants to the Washington Department of Ecology’s (WDOE) cleanup levels. HRC was chosen for groundwater remediation due to its ability to provide a low cost solution for site ...

  • Enhanced Vapor Intrusion Mitigation via Horizontal Remediation Wells

    Vapor Intrusion (VI) is a potential concern at any building - existing or planned, located near soil or groundwater contaminated with volatile organic compounds (VOCs). Conventional installation technologies (vertical wells) can fall short, especially when large structures such as factories, hangars, and offices buildings are involved because they typically involve expensive and lengthy ...

  • Stream restoration - Case study

    ERC was hired as the General Contractor for the stream restoration of Mill Creek in South Western Ohio. Our scope of work included the construction of one (1) riffle, rock toe, buried grade control, grading, and complete site stream restoration. After mobilizing to the site ERC cleared and grubbed the entire site and then excavated 2,900 CY of soil. In order to align the stream and to slope the ...

  • Site 426: Fieldwork Goes On to Ensure Safety Near New Dorms

    Environmental Management is investigating the former location of a World War II-era chemical warfare material (CWM) storage yard. The location designated Installation Restoration Program (IRP) Site 426, lies east of the new dormitories between Rousamond Boulevard and Popson Avenue, west of South Muroc ...

  • 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 ...

  • Restoration of heathland case study

    Dr Phil Putwain has undertaken research over a period of 30 years on the restoration of lowland and upland heathland landscapes following severe disturbance by development projects on uncolonised mineral substrates on marginal farmland. The research findings were applied to practical implementation of heathland restoration on a large scale at sites throughout Britain ranging from the Orkney ...

  • Opportunities and challenges of integrating ecological restoration into assessment and management of contaminated ecosystems

    Ecosystem restoration planning near the beginning of the site assessment and management process (“early integration”) involves consideration of restoration goals from the outset in developing solutions for contaminated ecosystems. There are limitations to integration that stem from institutional barriers, few successful precedents and limited availability of guidance. Challenges occur in ...

  • A framework for establishing restoration goals for contaminated ecosystems

    As natural resources become increasingly limited, the value of restoring contaminated sites, both terrestrial and aquatic, becomes increasingly apparent. Traditionally, goals for remediation have been set prior to any consideration of goals for ecological restoration. The goals for remediation have focused on removing or limiting contamination while restoration goals have targeted the ultimate ...
