  • Treatability Study for Contaminated Soil Projects

    What is a Treatability Study? When done correctly, a treatability study can be an important component of the remedial investigation/feasibility study (RI/FS) and the remedial design/remedial action (RD/RA) process. Engineers use this tool to help identify the full range of remedial options that are available to their client regarding safe & cost-effective remedies in the ...

  • Soil Mixing- Case Study

    ERC was hired as the General Contractor for this project to treat organic contaminants found in the soil via in-situ chemical oxidation (ISCO).  To achieve this ERC excavated and stockpiled 2’ of overburden soils from the treatment area then utilized a 336sized excavator with a mounted transverse mixing head attachment to perform in-situ soil mixing on an approximately 9,943 square ...

  • Air sparge system - Case Study

    ERC was contracted to install an air sparge system in Central Ohio. Air sparging is an in situ remedial technology that reduces concentrations of volatile constituents in petroleum hydrocarbons adsorbed to soils and dissolved in groundwater. This involves the injection of contaminant-free air into the subsurface saturated zone, enabling a phase transfer of hydrocarbons from a dissolved state to a ...

  • Creek Channel & Floodplain Restoration Project - Case Study

    The ERC & Burgess & Niple team was selected as the design-build team to complete the design, permitting and construction work along Turtle Creek. The scope of work included the removal of a failing sheet pile wall, clearing and grubbing, excavation/embankment, re-alignment of the stream, installation of instream structures and rip-rap slope protection.  During the removal of the ...

  • Ozone Case Study

    Historic activities at the site involved degreasing and industrial clean-ing service using solvents, primarily tetrachloroethene (PCE) and trichloroethene (TCE) to support the growing aerospace industry in Southern California. Site investigations indicated the presence of volatile organic compounds (VOCs), including. PCE, TCE, ...

  • Full-scale application of nZVI: innovative geochemical barrier supported by direct current

    Massive contamination by chlorinated ethenes (CHCs) under an engineering plant showed to be problem for a near groundwater receiving river. The innovative approach including formation of nZVI reactive geochemical barrier was chosen by the remediation company MEGA. Moreover, a prolongation of activity of the applied NANOFER was achieved thanks to the usage of DC. Long-term monitoring and ...

  • Prj 9121 - Deactivation of radioactive water - Case Study

    Although radioactive isotopes are engaged for many applications (i.e. medicine, metallurgy, etc.), the major sources of soil and water contamination with radioactive substances are connected to nuclear waste processing and to uranium mining operations. One of the principal carcinogens is plutonium and any soil or water contaminated by plutonium should be carefully removed and disposed in ...

  • Multiparameter sonde used in combined remedy approach and saves $200,000 in potential costs - Case Study

    A former dry-cleaning site in the Pacific Northwest, Ultra Custom Care Cleaners, was found to be contaminated with PCE (perchloroethylene). According to the U.S. Geological Survey (USGS), PCE was widely used in the dry cleaning of fabrics since the 1940s. PCE is one of the most frequently detected VOCs (volatile organic carbons) in groundwater at a national scale (Moran 2004). PCE is highly ...

  • New perspectives in the use of horizontal wells for assessment and remediation

    Abstract Remediation technologies can sometimes be established, but are not prevalent, for a variety of reasons; however, they can be subject to the forces of change. In some cases, creative economics promotes newuses, but also process improvements can drive newapplications and levels of acceptance. This is what is happening with the deployment of horizontal wells for site assessment ...
