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 ... .  
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  
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  
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 .  
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.  For more information and to register, see .  
ITRC What's New with In Situ Chemical Oxidation? - September 20.  
This seminar presents updated guidance and technology  
advancement information for In Situ Chemical Oxidation. Topics  
include a regulatory discussion related to ISCO implementation;  
details on the chemistry behind ISCO technology; considerations  
for system design and application, including health and safety;  
and performance evaluation information. The course is  
based on the ITRC's In Situ Chemical Oxidation of Contaminated  
Soil and Groundwater, Second Edition (ISCO-2, 2005), with  
sections on technology overview and applicability, remedial  
investigations, safety concerns, regulatory concerns, injection  
design, monitoring, stakeholder concerns, and case studies.  For  
more information and to register, see or .  
ITRC Characterization and Remediation of Soils at Closed  
Small Arms Firing Ranges - September 22.  This seminar  
introduces the participants to the various physical (including  
hydraulic), chemical, and biochemical mechanisms available to  
treat or stabilize SAFRs after some unique characterization  
challenges are overcome.  This training is based on the ITRC  
document entitled: Technical & Regulatory Guidance Document  
for Small Arms Firing Range Remediation Technologies.  For  
more information and to register, see  or  
ITRC Permeable Reactive Barriers: Lessons Learned and New  
Directions - October 6.   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).  For more information and to  
register, see  or

Abstracts of Remediation Case Studies, Volume 9 (EPA  542-  
R-05-021).  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).  View or download at

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  
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
