Upcoming Live Internet Seminars

ITRC Planning and Promoting of Ecological Reuse of Remediated Sites - December 5. This training is based on the ITRC Technical and Regulatory Guideline: Planning and Promoting Ecological Land Reuse of Remediated Sites (ECO-2, 2006). The document presents a process to promote ecological land reuse activities considering natural or green technologies instead of more traditional remedies. The guidance demonstrates that natural or ecological end-uses are valuable alternatives to conventional property development or redevelopment. Ecological benefits and a process for calculating their value are included in the guidance and reviewed in this training. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/studio .

ITRC Overview of Direct-push Well Technology for Long- term Groundwater Monitoring - December 7. Direct-push wells have been used for temporary groundwater monitoring purposes for many years but are generally prohibited for use as long-term groundwater monitoring wells. Recent research indicates that direct-push wells are as well suited for long-term environmental groundwater monitoring purposes as conventionally constructed wells. This training introduces ITRC's The Use of Direct-push Well Technology for Long-term Environmental Monitoring in Groundwater Investigations (SCM-2, 2006), provides a background in the principles of direct-push wells, and presents the state of the art regarding recent research. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/studio .

ITRC Risk Assessment and Risk Management: Determination and Application of Risk-Based Values ? December 12. This training course describes the development and application of risk- based screening values. The first module provides a review of key risk assessment concepts related to risk management. The second module focuses on the process by which risk-based levels are derived in different states. The third module examines the application of risk assessment to remediation operations in two case studies providing examples of how risk assessment has actually been implemented, based upon research and case studies conducted by the ITRC Risk Assessment Resources team. This training course describes a number of the reasons behind variations in risk-based screening values and their use in risk management. For more information and to register, see http://www.itrcweb.org or http://clu-in.org/studio .

Revegetation and Restoration of an Oil Contaminated Wetland in Northern New Jersey ? December 14. This presentation will attempt to show that a carefully supervised cleanup followed by a scientifically driven monitoring program can be effective in removing oil from a sensitive wetland habitat using the Green Pond Oil Spill Removal project as the prime example. A monitoring program for determining the success of the revegetation/restoration effort was conducted. Species composition and productivity measurements were an integral part of the parameters to measure the progress of the effort to determine comparability between the remediated site and undisturbed wetlands. The presentation will incorporate all that has been learned from the removal activity in terms of How Clean is Clean as applied to an oil contaminated fresh water wetland. This information should be useful for decision makers, responders, and consultants alike when faced with remediating disturbed or contaminated habitats. For more information and to register, see http://clu-in.org/studio .

Documents and Web Resources

Treatment Technologies for 1,4-Dioxane: Fundamentals and Field Applications (EPA 542-R-06-009). 1,4-Dioxane is a solvent stabilizer frequently found at contaminated sites where methyl chloroform (1,1,1-trichloroethane) was used for degreasing. This report profiles the occurrence and properties of 1,4-dioxane and provides a summary of the available remedial technologies. The information presented should prove useful to project managers and other regulatory officials who oversee cleanup of contaminated groundwater, particularly where chlorinated solvents are the principal contaminant. Consultants, including hydrogeologists, remediation engineers, and modelers, should also find this report useful, as should water utility operators and regulators (November 2006, 30 pages).

Hazardous Waste Clean-Up Information (CLU-IN) On-line Remediation Databases Fact Sheet (EPA 542-F-06-006). This factsheet describes databases available on CLU-IN (http://clu-in.org) sponsored by the U.S. EPA's Office of Superfund Remediation and Technology Innovation (OSRTI). These databases provide timely information about selected pilot- and full-scale applications of innovative treatment and site characterization technologies for EPA remedial project managers (RPM), other federal and state personnel, consulting engineers, technology developers and vendors, remediation contractors, researchers, community groups, and individual citizens. They have recently been updated, reformatted, and made available through a Universal Search Engine. They facilitate and encourage the hazardous waste remediation community to share their knowledge and experiences about innovative technologies (September 2006, 4 pages). View or download at http://clu-in.org/techpubs.htm .

New In Situ Flushing Profiles. EPA has developed this CLU-IN area to summarize timely information about selected full- and field-scale applications of in situ flushing technologies. This area provides information about ongoing and completed applications to treat chlorinated solvents, petroleum products, metals, explosives, and PCBs in groundwater and soil. The project profiles provide summary information about each application, including relevant site information, contaminants and media treated, technology design and operation, cost information, and performance results, as well as point(s) of contact and references. Projects for this Web site are collected using information from technical journals, conference proceedings as well as other published sources including Record of Decisions (RODs) or 5-year reviews. As of April 2006, the Web site includes information on 23 in situ flushing project profiles including completed and on-going applications. For more information, see http://clu-in.org/products/isf/ .

Revegetating Landfills and Waste Containment Areas Fact Sheet (EPA 542-F-06-001).

Grant Guidelines to States for Implementing the Secondary Containment Provision of the Energy Policy Act of 2005. The UST provisions of the Energy Policy Act focus on preventing releases and direct EPA to help states comply with new UST requirements. EPA and states, working closely with other stakeholders, developed the secondary containment grant guidelines, which include definitions, requirements, and examples for states choosing to implement the secondary containment provision. States receiving federal funds must implement the secondary containment requirements by February 8, 2007. EPA regions will incorporate the guidelines into their future grant agreements with states (November 2006, 13 pages). View or download at http://www.epa.gov/oust/fedlaws/final_sc.htm .

API Launches New Soil and Groundwater Website. API has reorganized its website to make it easer to find technical information related to subsurface fate and transport and natural attenuation of fuel constituents, site characterization and remediation. Sections of the website are devoted to oxygenates (including MtBE and ethanol), LNAPL and petroleum vapor intrusion. For more information, see http://www.api.org/groundwater .

EUGRIS Corner. New Documents on EUGRIS, the platform for European contaminated soil and water information. See the following link to access the following documents: http://www.eugris.info/Whatsnew.asp .

1) How to use EUGRIS to prepare for the forthcoming European Framework 7 research and development program (open to US organizations as "third country" participants) http://www.eugris.info/DisplayNewsItem.asp?NewsID=376 . A call for proposals for the new Framework 7 Programme is expected December 2006 to January 2007. FP7 will last 7 years and have a budget greater than 50 billion over this period. The programme is open to organizations in the EU and many countries outside the EU. For the most part countries outside the EU can join FP7 proposals only if they can secure their own funding. The benefit is therefore the gearing of being able to participate in a much larger project. FP7 includes a range of funding lines for proposals related to soil and water topics.

2) Copies of older UK contaminated land guidance documents scanned to PDF at http://www.eugris.info/DisplayNewsItem.asp?NewsID=371 . Some contaminated land guidance still in use in the UK dates back to the 1980s and has not been available in downloadable form, in particular: Contaminated Land Reports (CLRs) 1 to 6 and 12, and Publications of the former Interdepartmental Committee on the Redevelopment of Contaminated Land (ICRCL). Defra and the Environment Agency have recently completed scanning these to PDF, and these are now available for download.
