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 ...

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 ...

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 ...

Guest editorial: the IRIS assessment of inorganic arsenic: is science being hijacked?

The arsenic IRIS assessment exemplifies the current administration’s unwillingness to walk its own talk on transparency and scientific integrity. Early in her role as the EPA Administrator, Lisa P. Jackson expressed her now familiar mantra that regulatory initiatives must be “transparent” and risk assessments must be conducted to “ensure the highest levels of scientific ...

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. ...

Depth of the biologically active zone in upland habitats at the Hanford Site, Washington: Implications for remediation and ecological risk management

Soil invertebrates, mammals, and plants penetrate and exploit the surface soil layer (i.e., the biologically active zone) to varying depths. As the U.S. Department of Energy remediates radioactive and hazardous wastes in soil at the Hanford Site, a site‐specific definition of the biologically active zone is needed to identify the depth to which remedial actions should be taken to protect 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, ...

Biotechnology of hydrocarbon bioremediation in soil washing slurry

Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

Pilot Project at Tidewater Terminals

The pilot project was undertaken to determine the effectiveness of AgroRemed for cleanup of contaminated soil within a short turn around time as claimed by SARVA. The results were monitored on 10th day and 20th day before closing the pilot. It is seen from the results that there was a reduction of more than 30% in the values of TPH on 10th day and at the end of 20 days there was a reduction in ...

Effectiveness of a Sediment Time Critical Removal Action – PCB Reduction in Fish Tissue, Surface Water and Sediment via Wet Excavation

Documenting successful remediation of polychlorinated biphenyl (PCB)‐contaminated sediments is limited; potentially due to inadequate monitoring methods, complexities associated with the environment, and selected remedial techniques. At some sites, absence of appropriate baseline and post‐removal monitoring limits proper evaluation of remedial efficacy. Accurate interpretation of interactions ...

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 ...

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, ...

Fuel Oil Spill during maintenance in Ohio

During replacement of oil furnace by an HVAC contractor in Ohio, there was an accidental release of almost 250 gallons of No. 2 heating oil in the basement. The oil seeped below the concrete surface and the smell of heating oil fumes was so strong that the home owner was advised to relocate in a hotel to prevent chemical burn of throat tissues. Environment company in charge of the cleanup removed ...

A method for Cleaning foreshores case study

Introduction During a recent incident in the UK, it was important that the ecological disturbance in respect to natural vegetation and wildlife should be disturbed as little as possible. For this reason, no equipment of any description was allowed to be used. More than 20, 000 litres of oil was estimated to have made landfall on this foreshore. We decided that it would be sufficient to unroll ...
