  • Heavy Metals Contaminated Soils Site Characterization

    What is Heavy Metals Contaminated Soils Site Characterization? The EPA requires a Toxicity Characteristic Leaching Procedure (TCLP, EPA Method 1311) test to characterize heavy metals contaminated soils and determine how they should be disposed. Soils exhibiting hazardous characteristics, typically leaching metals at greater than 5.0 mg/L, need to be disposed of at a ...

  • Remediate former service station - Case Study

    ERC was hired as the General Contractor for this project to remediate the former service station.  Gasoline underground storage tanks (USTs) were previously removed however historical releases had contaminated both soil and groundwater at the site.  The remedial activities for this project included excavation and off-site disposal of petroleum contaminated soils, as well as the addition ...

  • 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 ...

  • 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, ...

  • Drilling oil recovery from drill cuttings XXL - Case study

    Worlds largest treatment facility for recovery of drilling fluids The two largest oil & gas companies in Azerbaijan engaged econ industries to design and build the world's largest recycling facility for drilling mud. The brand-new Waste Management Center is located south of Baku and consists of two identical VacuDry® 12,000 x 2 plants, capable of treating 240 tons of drilling mud ...

  • Remediation of a mercury contaminated site - Case study

    Remediation of mercury contaminated industrial site for future expansion of industrial area. 70,000 tons of mercury contaminated soil and building rubble have to be cleaned in an industrial facility in the south of France until 2013. For the realization of this remediation work, an econ industries VacuDry 12,000 has been in operation since early 2011. After the treatment the mercury ...

  • A Procedure to assess Contaminated Soil Ecotoxicity

    Abstract :Two polluted soil samples were assessed for both acute (Microtox®,Daphnia magna,Thamnocephalus platyurus) and chronic (Pseudokirchneriella subcapitata) toxicity, as well as for genotoxicity (Mutatox®). Bioassays were performed on soil water leachates and on soil solvent extracts to characterize not only the water soluble pollutants but also to evaluate less soluble pollutants or ...

  • 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 ...

  • Another step towards making mercury history

    econ industries is proud to announce the next project towards making mercury history: a delivery contract for a VacuDry® Unit going to India. A VacuDry® 3 000 plant will be deployed to clean-up mercury contaminated soil from a former factory. Due to the location of the factory and strict environmental regulations, an on-site remediation with highest cleaning efficiency was requested. The ...

  • Bioremediation of Naphthalene and Methylnaphthalene Isomers

    Petrox bioremediation accelerates the removal of naphthalene and isomers of methylnaphthalene.  These petroleum compounds are often slow to remediate due to their low volatility and strong affinity for absorption onto soil particles.  The remediation rate of these compounds is slower than BTEX compounds.  They often also rebound as the absorbed phase solubilizes following removal ...

  • Mapua, New Zealand - Case Study

    In collaboration with the New Zealand Ministry for the Environment and Tasman District Council, EDL undertook its largest project to date at the Fruitgrowers Chemical Company site in Mapua. 8,650 m3 of soil heavily contaminated with Lindane, DDT, Dieldrin, and Aldrin was treated at what was known as country’s most contaminated site. ...

  • Vapor Intrusion Testing/Sampling in Buildings

    What is Vapor Intrusion? Vapor intrusion occurs when volatile chemicals lodged in soil or groundwater rise to the surface and are released into the air. This can occur in the open air or into buildings, offices, factories, warehouses, vacant, or abandoned. Vapor intrusion testing/sampling is a method of determining if known or suspected ground contamination is a result in these chemical ...

  • I need a Phase I Environmental site assessment (Phase I ESA) Who do I call?

    A Phase I Environmental Site Assessment (Phase I ESA) A Phase I Environmental Site Assessment (Phase I ESA) is used to determine the liability to property buyers or financial institutions during mergers and acquisitions, refinancing of commercial real estate, and other situations in order to identify the environmental risks of a site and satisfy the “due diligence” efforts to ...
