  • Soil, sediment, and ground-water characterization and remediation technologies

    This issue of Technology News and Trends highlights “green remediation,” the practice of considering all environmental effects of remedy implementation and incorporating options to maximize the net environmental benefit of cleanup. The applications in this issue demonstrate increased sustainability that can be gained through use of renewable energy sources to power treatment systems or through ...

  • Remediation of petrol-contaminated sediments in a tropical environment

    Conventional and experimental methods were studied for the remediation of petroleum contaminated sediments from a dam previously used to collect acid run-off from a sulfur mine. The man-made lake had been neutralized, but bentonite rich sediments remained contaminated with very weathered hydrocarbons (sediments with ~50,000–60,000 mg/kg Total Petroleum Hydrocarbons were used in this study). ...

  • Remediation of the mercury-contaminated sediments in Svartsjoarna with Geotube - Case Study

    The Challenge Svartsjoarna in Sweden are located near Paulistrom. Through the lake, a small river runs into the river Eman. This Eman river is considered to be one of the most valuable water courses in Sweden. The river has a very high diversity of fish species and animal like otter. Some parts of the river have very well developed meander systems. For these reasons, a remediation had to ...

  • Using sediment cores to establish targets for the remediation of aquatic environments

    When assigning site-specific restoration targets for deteriorating aquatic systems, it is necessary to have an understanding of the undisturbed or background state of the system. However, the site-specific characteristics of aquatic systems prior to disturbance are mostly unknown, due to the lack of historical water and sediment quality data. This study aims to introduce a method for filling ...

  • An integrated assessment of sediment remediation in a Midwestern U.S. stream using sediment chemistry, water quality, bioassessment, and fish biomarkers

    A comprehensive biological, sediment, and water quality study of the lower Little Scioto River near Marion, Ohio, USA, was undertaken to evaluate the changes or improvements in biotic measurements following the removal of creosote‐contaminated sediment. The study area covered 7.5 river miles (RMs), including a remediated section between RMs 6.0 and 6.8. Fish and macroinvertebrate assemblages, ...

  • Presumptive Remedies

    A presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site. EPA is establishing presumptive remedies to accelerate site-specific analysis of remedies by focusing the feasibility study efforts. EPA expects that a presumptive remedy, when available, will be used for all CERCLA sites except under ...

  • Soil Remediation

    Contaminated sites by hazardous substances are a major environmental concern in Europe e throughout the world. Significant financial and human resources are devoted for the remediation of such sites. Many steps have been taken to restrict or ban from use some contaminants (PCBs, IPA, CLB-derivatives) and reduce discharge of others. However, contaminants can persist for many years in soil and ...


  • Bioremediation Technologies for Marine Sediments

      USA – Baltic International Symposium on Advances in Marine Environmental Research, Monitoring and Technologies. Klaipeda, Lithuania. June 15-17, 2004 Global commerce relies heavily on waterborne transportation. Innovative, economical and environmentally sound ways to manage ...


  • Containment for Soil, Sediment, and Sludge

    Containment treatments 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, ...

  • Remedial strategy at superfund site calls for organophylic clay sediment cap case study

    Project: Port of Portland Nearshore Cap Location: Portland. OR Products: Bulk Organoclay Background: U.S. EPA and the Port of Portland signed a legal agreement to assess and clean up contaminated river sediment at the Port's marine Terminal 4. This agreement authorizes the first early action cleanup project in the Portland ...

  • In Situ Sediment Treatment Using Activated Carbon: A Demonstrated Sediment Cleanup Technology

    This paper reviews general approaches for applying activated carbon (AC) amendments as an in situ sediment treatment remedy. In situ sediment treatment involves targeted placement of amendments using installation options that fall under two general approaches: 1) direct application of a thin layer of amendments (which potentially incorporate weighting and/or binding materials) to surface ...

  • Reactive mat used in creosote sediment cap remedy at a Portland superfund site case study

    Project: McCormick & Baxter Superfund Site Location: Portland, OR Products: Organoclay Reactive Core Mat Background: The former McCormick and Baxter Creosoting Company is located in Portland, Oregon on the Willamette River. This Superfund Site encompasses approximately 41 acres of land and an additional 23 acres of ...

  • Monitoring exposure of brown bullheads and benthic macroinvertebrates to sediment contaminants in the Ashtabula River before, during, and after remediation

    In 2007, approximately 420,500 cubic meters of contaminated sediment were removed from the Ashtabula River by dredging. The primary objective of this study was to monitor contaminant exposure in fish and macroinvertebrates before, during, and following dredging. This was done by measuring tissue concentrations of polychlorinated biphenyl (PCB) and polycyclic aromatic hydrocarbon (PAH) in brown ...

  • From sediment to tissue and tissue to sediment: An evaluation of statistical bioaccumulation models

    Biota–sediment accumulation factors (BSAFs) and biota–sediment accumulation regressions (BSARs) are statistical models that may be used to estimate tissue chemical concentrations from sediment chemical concentrations or vice versa. Biota–sediment accumulation factors and BSARs are used to fill tissue concentration data gaps, set sediment preliminary remediation goals (PRGs), and make ...

  • Data Requirements for Soil, Sediment, and Sludge

    Site soil conditions frequently limit the selection of a treatment process. Process-limiting characteristics such as pH or moisture content may sometimes be adjusted. In other cases, a treatment technology may be eliminated based upon the soil classification (e.g., particle-size distribution) or other soil characteristics. Soils are inherently variable in their physical and chemical ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...
