  • 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 ...

  • 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 ...

  • River Stabilization & Realignment- Case Study

    ERC was hired as the General Contractor to stabilize and realign the North Fork Licking River immediately upstream from a rail road bridge. The project required clearing, grubbing, excavation and regrading of the existing point bars to realign the river thalweg. To stabilize the banks we installed j-hooks, flexamat, turf reinforcement matting, erosion control blanket with seed and plantings. We ...

  • 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 ...

  • The METS Process in Brief/2019

    The METS remediation process equipment is about the size of a large SUV. It is fully mobile and self-propelled. Previously excavated soil is deposited in the hopper at the top of the apparatus by a conventional front-end loader. Very large debris, such as rock, concrete or asphalt, is usually screened off at the hopper opening. From the hopper, the soil is transferred in a regulated flow to a ...

  • 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, ...

  • Wet Ice Blasting for Mold Remediation vs Dry Ice Blasting

    Before we discuss the use of wet ice and/or dry ice blasting in the mold remediation process we need to provide a simple explanation of the difference between mold removal and mold remediation. If you own a company that provides mold remediation some of today’s post will be old hat; but for those reading who are just learning, we need to first start with ...

  • 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 ...

  • Crookston Crookston Landslide Stabilization - Case Study

    Project Description In 2003, a landslide developed along the Red Lake river bank inside the city of Crookston, Minnesota. Although several attempts were made to solve the problem, in 2008, a second event occurred, and extensive instrumentation was then put in place to monitor the slope and gain a better understanding of the situation. In 2013, the Minnesota Department of Transportation ...

  • Ion Exchange Resin Activation

     Ion exchange resin contains a certain amount of water, which should be kept as much as possible during transportation and storage. If the resin is dehydrated during storage, it should be soaked in concentrated salt water (about 10%) and then diluted gradually. The resin should not be directly put in water to avoid rapid expansion and crushing. In long-term storage, strong resin should ...
