Special Announcements Brownfields Job Training Grants-Request for Applications (RFA). EPA's Office of Brownfields Cleanup and Redevelopment is now requesting applications for brownfields job training grants. The goals of the Job Training Program are to prepare trainees for future employment in the environmental field and facilitate cleanup of brownfields sites contaminated with hazardous substances, pollutants, contaminants, and petroleum. Applications are due September 16, 2005. For more information, see http://www,epa,aov/swerosps/bf/announca,htm . Webcast: 25 Years of Contaminated Land Management - Achievements and Work Still to Be Done. Live from ConSoil in Bordeaux, France, October 4, 2005. The webcast is sponsored by the European Soil and Groundwater Remediation Information System (EUGRIS), U.S. Environmental Protection Agency, the Network for Industrially Contaminated Land in Europe (NICOLE), and ConSoil 2005. This webcast includes two panels with four speakers each. Panel 1 is titled Shifts in Contaminated Site Management in the EU and US and offers insight to changes in the US and Europe to contaminated site management over the past 25 years, and insight into future directions. Panel 2 is titled, From Site Screening to Redevelopment, Progress in Every Step. Panelists TechDirect: September 1, 2005 1 of 5 clu-in.ora/newsletters ------- will discuss technical advances and policy shifts that allowed them in the field of contaminated site management go hand in hand and feed off each other. Presentations in this panel review major breakthroughs and their value going forward. Registration is required for each panel at htto ://www.clu in .ora/stud io/consoil/. Internet Seminars NIEHS DNAPLs - Above-Ground (Ex situ) Chemical/Physical Remediation Methods - September 7. This continues our series of web-based seminars focusing on issues for DNAPL- contaminated hazardous waste sites. This second event will feature Dr. Chang Yul Cha, Cha Corporation, and Eric Betterton, University of Arizona. Dr. Cha will discuss his recent NIEHS SBIR-supported development of Microwave Technology for Superfund Site Remediation. Dr. Eric Betterton, of the University of Arizona, will present his work investigating the difficulties associated with the destruction or final disposal of chlorinated solvents that are traditionally recovered from contaminated sites via pump and treat or soil vapor extraction methods. For more information and to register, see http://clu-in.org/studio . EPA Jump-Starting Ecological Restoration - September 8. The goal of this seminar is to examine the relevance and importance of ecological restoration in the Superfund program and to discuss implementation strategies and specific techniques to speed the recovery of disturbed and contaminated land. Participants will learn why ecological restoration is important to the Superfund program; gain an understanding of the relationship between land disturbance, functioning ecological systems, and how restoration projects are managed; and learn various techniques. The seminar also will address in-situ remediation of metal contaminated soils. In short, participants can expect to learn how to jump-start restoration at a site.

This training presents updated information regarding new developments, innovative approaches, and lessons learned in the application of PRBs to treat a variety of groundwater contaminants. The information will be presented by reviewing the approaches and results at several sites where PRBs have been deployed. The training is based on the ITRC guidance document titled Permeable Reactive Barriers: Lessons Learned / New Directions (PRB-4, 2005).

This new report, published by the Federal Remediation Technologies Roundtable (FRTR), is a collection of recently published abstracts summarizing 13 cost and performance case studies on the use of remediation technologies at contaminated sites. The case studies include several different technologies for treating soil or groundwater contamination or both, with 7 reports addressing soil cleanup and 8 reports concerning groundwater (July 2005, 81 pages).

Comparison of Diffusion- and Pumped-Sampling Methods to Monitor Volatile Organic Compounds in Ground Water, Massachusetts Military Reservation, Cape Cod, Massachusetts, July 1999-December 2002 ( SIR 2005-5010). This study was done cooperatively by the U.S. Geological Survey (USGS) and the TechDirect: September 1, 2005 3 of 5 clu-in.ora/newsletters ------- Air Force Center for Environmental Excellence (AFCEE). It evaluates the applicability of diffusion sampling for monitoring VOC concentrations in ground water collected from monitoring wells. The applicability of the diffusion-sampling method is measured by the utility of the method to detect concentrations of VOCs similar to those obtained by the pumped-sampling method. VOC concentrations in samples collected by the diffusion- and pumped-sampling methods are compared with each other; and in cases where the concentrations did not match, bias in the diffusion-sampling method is assessed. Comparisons are made between well, diffusion-sampler, aquifer, and geochemical characteristics, and the degree of agreement of the sampling methods. These comparisons add to the current understanding of diffusion samplers by examining how the samplers work in wells with short screens (2-5 ft long) (Spring 2005, 60 pages).

The Inventory of Sources and Environmental Releases of Dioxin-Like Compounds in the United States: The Year 2000 Update (External Review Draft, EPA/600/p-03/002A). This report, published by the U.S. EPA, is to present the most current inventory of sources and environmental releases of dioxin-like compounds in the United States. This is a comprehensive overview of what is known about sources that release dioxin into the air, land and water of the United States. It is a listing of sources by category combined with estimates of releases of dioxin to the environment from these sources. Estimates of environmental releases are associated with three calendar years: 1987, 1995 and 2000. This provides a point of reference for observing any changes in the amount of dioxin that is released to the environment with the passage of time (March 2005).

This report was published by the EPA Office of Underground Storage Tanks. It covers recommended inspection guidelines and best management practices for sumps associated with your UST system. This manual will help you identify and inspect the sumps associated with an UST system, including the equipment in sumps. It will explain some simple steps you can take to maintain sumps and the equipment in sumps, as well as identify potential problems. The report also provides tips for fixing common problems before they cause a release to the environment (May 2005, 20 pages). View or download at http://www.epa.aov/swerust1/pubs/sumpmanl.htm .
