  • Common Treatment Train for Radionuclides

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for radionuclides is illustrated below. Radionuclide contaminated soil is first excavated from the contamination soil and transported to a vitrification site. During vitrification, the contaminated soil is molten at extremely high temperatures. Radionuclides are incorporated into ...

  • Springtown, Texas - excavation; open-hole chemical oxidation case study

    When a tanker truck overturned on this road near Springtown, Texas, approximately 8,000 gallons of gasoline was spilled. Some of the fuel burned, discoloring the pavement, but a large portion of the fuel seeped into the sandy soils. Immediately after the accident, local responders excavated some of the most severely contaminated soil, but excavation was discontinued when groundwater was ...

  • CASE STUDY - Moncton, NB Oulton Business School

    The majority of the subsurface contamination was found present under one quarter of the building and associated cornerclassrooms. These classrooms were temporarily sealed off from the rest of the building for health and safety reasons. A large window and section of the brick wall was then removed to allow a mini-excavator access to the classroom. The concrete floor was also removed and the ...

  • VOCs Reduces Below Federal MCLs using HRC

    Summary Subsurface investigations at a dry cleaning facility revealed elevated levels of PCE and other regulated daughter products. HRC injection was chosen to accelerate the degradation of the entire range of VOCs. HRC slowly releases hydrogen, enhancing reductive dechlorination in an anaerobic environment. Additionally, HRC Primer, a less viscous version of HRC, was also used to reduce ...

  • Successful Pilot Test Results in Full-Scale Treatment of Large BTEX Plume

    CASE SUMMARYRefueling Station – Algonquin, IL Leaking underground storage tanks at a refueling station resulted in a benzene, toluene, ethylbenzene and xylene (BTEX) plume in the underlying sand/gravel aquifer. The plume covered 1-acre and extended 390 feet downgradient from the source area, with a total BTEX concentration exceeding 24,000 parts per billion (ppb). In an ...

  • Common Treatment Train for Explosives

    In general, no single technology can remediate an entire site. Several treatment technologies are usually combined at a single site to form what is known as a treatment train. A system diagram of a common treatment train for explosives is illustrated below. Explosive contaminated soil is first excavated from the site and transported to a windrow composting site. During windrow composting, ...

  • Recovery of lead from bullet berms on shooting ranges using Ekokem`s method - Case Study

    Ekokem has developed a method by which it is able to separate bullets from berm soil. The method used for separation is based on the electromagnetic properties of lead and on sensor technology. A considerable number of bullets accumulate on shooting ranges every year. It is important to remove them from outdoor shooting ranges as the lead they contain can leach into the soil, ...

  • In-situ Technology for Clean up of Halogen Contaminated Sites - Process West case study

    Halogenated volatile organic solvents are found in the soil or ground-water at many former and active industrial sites. Fortunately highly effective remediation technologies are available to restore these former brownfields to a healthy state. The range of technologies includes the traditional approach where the contaminated soil is excavated and the volatile halogenated contaminants are ...

  • PCE and TCE Remediation Continues Years After Injection

    Site Summary Subsurface investigations at this dry cleaning facility revealed elevated levels of PCE and TCE in groundwater and soil. Accelerated bioremediation using HRC was selected for use at the subject site as it offered a groundwater remediation method that would not interrupt on-going facility operations while effectively supporting the degradation of the contaminants. Approximately 250 ...

  • Overfill Spill at a Commercial Gas Station Results in NFA

    Site Summary This service station was approximately 150 feet from Peapack Brook, a stocked trout stream. In 1993, a petroleum hydrocarbon overfill spill occurred contaminating surrounding contaminated soils and underlying groundwater. In an effort to protect the stream from migrating BTEX, TBA, and MTBE plumes, two downgradient ORC barriers were installed. Additionally, following the excavation ...

  • Case study - EPH in soil with diesel and home heating oils

    Sitelab’s UVF-3100 analyzer is a popular tool when excavating soils contaminated by fuel oils from underground storage tanks (USTs). These studies show the accuracy testing samples for Extractable Petroleum Hydrocarbons, EPH C11- C22 aromatic hydrocarbons. Samples are extracted in solvent using test kits and measured on the UVF analyzer’s EPH optics, calibrated to Sitelab’s PAH ...

  • Groundwater remediation pump and treat carberry, Manitoba case study

    Executive Summary Two of four underground gasoline tanks were removed from an old service station located in Carberry, Manitoba a number of years after the facility ceased operating. Two tanks were left on site and were used until 1985, when Manitoba Environment was notified that a domestic well in the vicinity of the abandoned site was contaminated with gasoline. The remaining ...

  • A Citizen`s Guide to Chemical Dehalogenation

    What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they ...

  • Containment for Ground Water, Surface Water, And Leachate

    Containment measures are often performed to prevent, or significantly reduce, the migration of contaminants in soils or ground water. Containment is necessary whenever contaminated materials are to be buried or left in place at a site. In general, containment is performed when extensive subsurface contamination at a site precludes excavation and removal of wastes because of potential hazards ...
