  • Barium Sulfate: A Protocol for Determining Higher Site-Specific Barium Cleanup Levels

    Abstract Although different barium compounds are known to exhibit vastly different toxicities, cleanup standards for barium in soil or sediment at environmental corrective action sites are typically based on total barium concentration without regard for the specific barium compounds present. However, the Texas Commission on Environmental Quality (TCEQ) has recently agreed that the insoluble ...


  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Temperature effects on bioremediation of PAHs and PCP contaminated South Louisiana soils: a laboratory mesocosm study

    Goal, Scope and Background. Temperature and soil moisture content are important environmental variables in bioremediation technologies.Optimizing these variables in-situ would enhance andmaintain remediation of hazardous wastes during cold winter seasons or in cold regions and may lead to reduced maintenance and/or cost. The effect of elevated temperature and soil moisture on bioremediation ...


  • New ASTM Test Method Offers Quick and Easy Oil and Grease Measurement for Water and Soil Samples

    Onsite Field Measurement of Oil and Grease A quick and easy field analysis method for determining oil and grease concentration levels is important for both offshore oil platforms and soil remediation sites.. Prior to the Montreal Protocol, infrared (IR) analysis using Freon as an extraction solvent was a widely used field and laboratory method. In 1999, the U.S. EPA promulgated Method 1664A ...

  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...

  • PCP Confidential Client, Northwest USA

    Northwest, USA Summary Adventus’ DARAMEND® technology was selected to remediate approximately 6,000 tons of soil impacted with pentachlorophenol (PCP) at a former chemical manufacturing facility located in the Northwest. Excavated soil was placed in a lined bioremediation cell in a 2 ft layer for treatment. The Challenge To reach a remedial goal of less ...


  • Terramend, Heavy Oil & Diesel Fuel, Ontario, Canada

    Project Ex Situ Treatment of Soil Containing Hydraulic Oil and Diesel Fuel Summary Ex situ treatment of approximately 4,000 tons of soil impacted with hydraulic oil and diesel fuel at a former manufacturing facility in Georgetown, Ontario were treated using Adventus' TERRAMENDT technology. TERRAMEND™ effectively reduced contaminant concentrations to below the ...


  • Phtalates Confidential Client, Northeast, USA

    Project In Situ Treatment of Bis (2-ethylhexyl) phthalate (BEHP) Impacted Soil Summary DARAMEND® technology was selected as the remedial option of choice for the in situ treatment of 14,000 tons of BEHP impacted soil at a former plastics manufacturing facility in New Jersey. Surface soil (0-2 ft) was cleared of oversized debris and boulders (>6') using a ...


  • THAN Superfund Site (Pilot), Montgomery, Alabama, USA

    Montgomery, Alabama, USA Project Bioremediation of Pesticide Impacted Soil/Sediment Summary Soil and sediment (~4,500 tons) impacted with Toxaphene, DDT, DDD and DDE were excavated from impacted areas on the site, including a surface water drainage way. Impacted soils were placed in a prepared bed on site and a cycled, anaerobic/aerobic bioremediation ...


  • Joliet Army Ammunition Plant (JAAP)

    Wilmington, Illinois, USA Project Bioremediation of Soil Containing Organic Explosives Summary DARAMEND® bioremediation effectively reduced the concentrations of TNT, DNT and Tetryl during two separate pilot-scale demonstrations on contaminated soil from the JAAP. DARAMEND® bioremediation was also effectively applied during a full-scale (3,000 ton) ...


  • Risks from Renegade Nanoparticles during field deployments within NanoRem

    The aim of NanoRem is to support and develop the appropriate use of nanotechnology for contaminated soil and groundwater remediation. NanoRem focuses on facilitating practical, economic and exploitable nanotechnology for in-situ remediation. This can only be achieved in parallel with a comprehensive understanding of the environmental risk-benefit balance for the use of nanoparticles (NPs). One ...

  • Risk assessment and brownfields-determining exposure to site contaminants

    The USEPA’s Brownfields Program was developed to facilitate the rehabilitation of contaminated property for re-development. EPA has set forth criteria that must be met for a revitalized property to be used for residential, commercial or industrial purposes. The main thrust of these criteria is the long-term protection of residents or visitors (including shoppers and business employees). As ...

  • Quantitative risk assessment for contaminated sites in Spain

    Environmental Quantitative Risk Assessment is one of the key factors in the Decision Making Process for contaminated sites. Numerous decisions have to be made before, during and after conducting a quantitative risk assessment.Risk assessment is based on the information gathered previously: Historical information (Phase I) Site characterization (Phase II) Toxicological ...

  • Properties and Behavior of Explosives

    Information presented for SVOCs may also be appropriate for many of the contaminants presented in this subsection. The term 'explosive waste' commonly is used to refer to propellants, explosives, and pyrotechnics (PEP), which technically fall into the more general category of energetic materials. These materials are susceptible to initiation, or self-sustained energy release, when present in ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...
