ITRC LNAPL Training Parts 1, 2, and 3 - March 22, 23, and 24, 2011. Light non-aqueous phase liquids (LNAPLs) are organic liquids such as gasoline, diesel, and other petroleum hydrocarbon products that are immiscible with water and less dense than water. LNAPLs are important because they are present in the subsurface at thousands of remediation sites across the country, and are frequently the focus of assessment and remediation efforts. Part 1 of this training course explains how LNAPLs behave in the subsurface and examines what controls their behavior. Part 1 also explains what LNAPL data can tell you about the LNAPL and site conditions. Relevant and practical examples are used to illustrate key concepts. Part 2 addresses LNAPL characterization and site conceptual model development as well as LNAPL recovery evaluation and remedial considerations. Specifically, Part 2 discusses key LNAPL and site data, when and why those data may be important, and how to get those data. Part 2 also discusses how to evaluate LNAPL recoverability. Part 3 uses the LNAPL conceptual site model (LCSM) approach to identify the LNAPL concerns or risks and set proper LNAPL remedial objectives and technology-specific remediation goals and performance metrics. Part 3 also provides an overview of the LNAPL remedial technology selection framework. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/live .

Final Report: Independent Design Review, Celanese Fiber Operations Superfund Site, Shelby, North Carolina, EPA Region 4 (EPA 542-R-11-001). The Celanese site is located in Shelby, North Carolina. Operation of the P&T system was discontinued on a trial basis for two years to evaluate monitored natural attenuation as a potential ground water remedy. The system has not been restarted. EPA Region 4 is requesting a third-party review to help determine if the system should be restarted, if a modified system should be restarted, or if another type of ground water remedial approach is warranted. This report provides a brief background on the site, a summary of observations made from the document review, and recommendations regarding future modifications to the existing remediation system (including associated investigation activities). The cost impacts of the recommendations are also discussed (February 2011, 38 pages). View or download at http://clu-in.org/techpubs.htm .

Final Report: Technical Assistance for the Somersworth Sanitary Landfill Superfund Site, Somersworth, New Hampshire, EPA Region 1 (EPA 542-R-09-010). The Somersworth Sanitary Landfill Site (Somersworth site) is a former landfill in southern New Hampshire that is on the National Priorities List (NPL). The landfill was closed in 1981 and has had a groundwater monitoring network since the 1980s. Groundwater remedies were installed by 2001, and the site is currently in the long-term monitoring phase of operation and maintenance (O&M). U.S. EPA Region 1 requested a review of the Somersworth site groundwater monitoring plan. Site monitoring data was reviewed and statistical and heuristic evaluations were performed using the Monitoring and Remediation Optimization System software (MAROS) in 2007. Inputs, results and recommendations for the groundwater monitoring network, including the results based on the MAROS analysis, were reviewed (July 2009, 55 pages).

Terrestrial Carbon Sequestration: Analysis of Terrestrial Carbon Sequestration at Three Contaminated Sites Remediated and Revitalized with Soil Amendments (EPA 542-R-10-003). This paper presents the results of a study conducted by U.S. EPA's Technology Innovation and Field Services Division (TIFSD) on the terrestrial carbon sequestration co-benefit of using soil amendments for remediation and ecological revitalization at three sites. Prior to this study, little research has been published evaluating and quantifying terrestrial carbon sequestration benefits associated with land remediated with soil amendments. TIFSD conducted this study to increase this knowledge base. We quantified soil carbon sequestration rates at three sites: Leadville, CO, Stafford, VA, and Sharon Steel, PA. This study was part of our methodology development for sampling and analysis of carbon in soils at amended sites (methodology finalized June 2010). The results of this study indicate that carbon is being sequestered at all three sites we studied (February 2011, 56 pages). View or download at http://clu-in.org/techpubs.htm .

Monitored Natural Attenuation of Inorganic Contaminants in Ground Water, Volume 3: Assessment for Radionuclides Including Tritium, Radon, Strontium, Technetium, Uranium, Iodine, Radium, Thorium, Cesium, and Plutonium-Americium (EPA 600-R-10-093). The U.S. EPA Office of Research and Development, in cooperation with the Office of Superfund Remediation and Technology Innovation and Office of Radiation and Indoor Air, recently published the last of a three-volume technical resource for selection of MNA as a site-specific remedy component for inorganic contaminants in ground water. Volume 3, Assessment for Radionuclides, addresses technical aspects of attenuation mechanisms and data collection for tritium, radon, strontium, technetium, uranium, iodine, radium, thorium, cesium, and plutonium-americium. The document emphasizes characterization of immobilization and/or radioactive decay processes that may control contaminant attenuation or flux reduction, as well as technical approaches to assess performance characteristics of the MNA remedy. A tiered analysis approach is presented to assist in organizing site characterization tasks (September 2010, 147 pages). View or download at http://www.epa.gov/nrmrl/gwerd/gw/mna.html .

Bioavailability of Dioxins and Dioxin-Like Compounds in Soil. The Risk Assessment Guidance for Superfund (RAGS) Part A discusses making adjustments to Superfund site-specific risk assessments when the medium of exposure in an exposure assessment differs from the medium of exposure assumed by the toxicity value (cancer slope factor, reference dose value, etc.) based upon site-specific bioavailability data. An important consideration in assessing risks from exposures to dioxin in soil is whether an adjustment is needed in the application of the oral cancer slope factor (CSF) and/or oral chronic reference dose (RfD) for 2,3,7,8-tetrachloro-dibenzo-p-dioxin (TCDD). This adjustment would account for differences in the bioavailability of TCDD (and toxicologically related polychlorinated dibenzo-p-dioxins [PCDD] and polychlorinated dibenzofuran congeners [PCDF]) in soil and in the test medium used in the critical study(s) on which the CSF and/or RfD were based (e.g., dietary exposure vs. exposure to soil). An adjustment would be considered appropriate if evidence were sufficient to indicate that the relative bioavailability (RBA) of the PCDD/F mixture in soil was less than 100%. This report presents a summary of the published literature and analysis of the available data regarding RBA of PCDD/F in soil (December 2010, 83 pages).

Contaminated Land Remediation Report. This report was compiled and authored by Contaminated Land: Applications in Real Environments (CL:AIRE). The aims of this research were to summarize the current understanding and utilization of different contaminated land remediation techniques, to identify current and likely future factors influencing their selection and to set out the relative economic, environmental and social costs and benefits (i.e., the sustainability) of each technique. The sustainability impact assessment section of the report develops further the principles of the Sustainable Remediation Forum (SuRF-UK), demonstrating how thorough qualitative sustainability assessments for remediation technology selection can be undertaken and developed. Remediation techniques have evolved significantly over recent years, and the aim is to help industry to identify all the available options and to avoid resorting to a default remediation solution which may have less well determined economic, environmental or social impacts (February 2011, 120 pages).
