  • Cleanup of Contaminated Soils at Municipal Park

    A municipal garden in Mandarituba, soil was contaminated with transformer oil and COPEL, the utility company was responsible for the cleanup and restoration of the contaminated soils. The company decided to use AgroRemed BR CTBA specially customized for applications in Brazil. The site was excavated and treated as biopile with AgroRemed BR CTBA. Both TPH values and VOC’s were acceptable and ...

  • Cleanup criteria for radionuclides in US surface soil

    The maximum concentrations of individual contaminants that will be allowed to remain in the environment after cleanup are developed on a case-by-case basis and may depend on site-specific risk analyses as well as stakeholder concerns. A database of cleanup criteria has been established from site-specific agreements at US Department of Energy (DOE) remediation sites and was used to analyse the ...

  • Wireless Real-Time Soil Data from Stevens Hydra Probe Soil Sensors Used In Contaminated Soil Cleanup Operation

    Up until the early 1970s when The US Congress passed The Clean Water Act, industrial chemicals and petroleum products were routinely dumped onto the ground or poured down wells. In those days, few people understood groundwater hydrology, and disposing of chemical waste underground seemed like a safe and easy solution. Depending on the chemistry, underground pollution can linger for centuries, ...

  • Soil and groundwater remediation

    At a site in northern Indiana on behalf of a multinational client, Troy Risk operated a groundwater remediation system to cleanup the source of chlorinated solvent impact to a groundwater aquifer system. Prior to 1988, the site was occupied by a manufacturing facility. In March 1995, chlorinated volatile compounds (CVOCs) were detected pursuant to due diligence for real estate refinancing. From ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • Recommendations to improve wildlife exposure estimation for development of soil screening and cleanup values

    An integral component in the development of media‐specific values for the ecological risk assessment of chemicals is the derivation of safe levels of exposure for wildlife. Though the derivation and subsequent application of these values can be used for screening purposes, there is a need to identify the threshold for effects when making remedial decisions during site‐specific assessments. ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • Establishing PCB Cleanup Levels for Historical Spills in Texas

    INTRODUCTIONPolychlorinated biphenyls (PCBs) are a mixture of chlorine atoms and biphenyl molecules that combine to form complex chlorinated organic compounds that were manufactured and widely used in the United States from the 1940s through 1978. The chemical characteristics of PCBs made them desirable for use because of their electrical properties and low flammability. Unfortunately, the PCBs ...

  • Editor’s perspective - solvent cleanup standards

    Risk-assessment science is a critical tenet of the remediation industry, as it is the underlying basis of the majority of cleanup work performed. However, risk-assessment science is, for the most part, poorly understood by a large portion of environmental professionals. Most seasoned professionals understand the basic risk-assessment concepts related to the dose-response and exposure duration ...

  • Field-scale cleanup of atrazine and cyanazine contaminated soil with a combined chemical-biological approach

    Received for publication August 12, 2008. A former agrichemical dealership in western Nebraska was suspected of having contaminated soil. Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with ...

  • Natural Attenuation in Soils

    Introduction Surface and subsurface soils have different characteristics in natural attenuation. Mobile contaminants in subsurface soils diffuse into soil vapor and aqueous phase and thus are relatively easily subject to natural subsurface processes that can attenuate these contaminants. Most high-molecular-weight (persistent) organic and many inorganic contaminants will be immobilized in the ...

  • Spill Cleanup of Fuel Contaminated Soils After Roadway Accidents Using In Situ Bioremediation

    Two case studies are presented in this paper, one study demonstrating revitalization of roadside vegetation through bioremediation after a spill of motor oil and in another case application of AgroRemed to sites affected by diesel spill with underlying utility cables. The TPH of the soil after bioremediation was reduced by more than 95% from 65,000 ppm in the first case while in the second case, ...

  • Furthering the derivation of predictive wildlife toxicity reference values for use in soil cleanup decisions

    The development of media‐specific ecological values for risk assessment includes the derivation of acceptable levels of exposure for terrestrial wildlife (e.g., birds, mammals, reptiles, and amphibians). Though the derivation and subsequent application of these values can be used for screening purposes, there is a need to identify toxicological effects thresholds specifically for making ...

Our objective was to characterize and remediate the contaminated site by a combined chemical-biological approach. This was accomplished by creating contour maps of the on-site contamination, placing the top 60 cm of contaminated soil in windrows and mixing with a mechanical high-speed mixer. ...

  • Regulatory considerations for the potential development and application of metal cleanup values

    A workshop titled, “Ecological Soil Levels–Next Steps in the Development of Metal Clean‐up Values,” was held September 17–21, 2012, in Sundance, Utah. The purpose of the workshop was to provide managers and decision makers at contaminated sites in North America with appropriate methods for developing soil cleanup values that are protective of ecological resources. The workshop focused on ...
