Special Announcements Superfund 25th Anniversary. Superfund will mark its 25th anniversary in December 2005. In commemoration, EPA is planning three major activities to capture the history of the Superfund program by allowing those involved to share their experiences. These commemorative activities consist of a national discussion on the changing nature of Superfund, an oral history project, and a photo history project. EPA is calling for photographic submissions for the photo history project. We encourage people to submit photographs that capture the people and places of Superfund, the human and environmental impacts of Superfund sites, and the changes in communities resulting from site cleanups. EPA will use selected photos to enhance the oral history project and to create an archive of Superfund images. In addition, EPA will select two photos representing each of its ten regions for later display. Guidelines for submitting photos are available on Superfund's 25th Anniversary web site at http://www,epa,aov/superfund/25anniversarv .

Upcoming Internet Seminars ITRC What is Remediation Process Optimization And How Can It Help Me Identify Opportunities for Enhanced and More Efficient Site Remediation? - May 5. This training discusses the value of optimization in efficiently and objectively setting and attaining remediation goals. Key elements of RPO that will be discussed in the training include: Appropriate use of up-to-date conceptual site models (CSM); Flexible Remedial Actions (RAs) operations considering technology limitations and risk assessments; use of treatment trains for each target zone, and developing performance objectives for each element; development of an exit strategy for each remedy component considering life-cycle factors; and life-cycle cost analysis as a decision-making tool with the requirement that protectiveness must be maintained or improved.

The focus of this ITRC training is EPA's guidance for remediating radioactively contaminated sites, which can facilitate cleanups that are consistent with how chemical contaminants are addressed, except where technical differences posed by radiation are addressed. In addition to cleanup and its associated guidance, this course introduces the participants to long term stewardship (LTS) challenges related to the large radioactively contaminated sites. This understanding of LTS issues is integral to the cleanup process and decisions made at the radiation sites. To register, see http://www.itrcweb.ora Of http://clu-in.ora/studio . ITRC Triad Approach: A New Paradigm for Environmental Project Management - June 7. This seminar introduces the Triad concept and highlights how this process can increase the effectiveness and quality of environmental investigations. This training explains the relationship of the Triad to previous regulatory guidance, and offers a discussion of issues that may affect stakeholders. The ITRC guidance document, Technical and Regulatory Guidance for the Triad Approach: A New Paradigm for Environmental Project Management (SCM-1, 2003), serves as the basis for this training course.

This document was developed by the Interstate Technology and Regulatory Council (ITRC). This document addresses the minimization of potential exposure to metals, especially lead, associated with shooting ranges. It is designed to assist range operators in developing, using, and monitoring environmental management plans at active outdoor small Tech Direct: May 1, 2005 3 of 6 clu-in.ora/newsletters ------- arms firing ranges. The central task in formulating an environmental management plan is the selection and implementation of effective and reliable pollution prevention and mitigation measures, otherwise referred to as best management practices (February 2005, 125 pages).

Assessment of Subsurface Chlorinated Solvent Contamination Using Tree Cores at the Front Street Site and a Former Dry Cleaning Facility at the Riverfront Superfund Site, New Haven, Missouri, 1999-2003 (Scientific Investigations Report 2004-5049). This report was published by the U.S. Geological Survey in cooperation with the U.S. EPA. It describes the assessment of subsurface chlorinated solvent contamination using tree cores at two sites that were investigated as part of the Riverfront Superfund Site. During an initial assessment in 1999, core samples were collected from 32 trees. Results from these samples were used to scope and design the subsurface characterization of soils and a ground-water monitoring network (2004, 41 pages).

This report was published by the U.S. Army Corps of Engineers. A reliable and inexpensive colorimetric method for perchlorate in water and soil extracts has been developed and tested with surface water, well water, bioreactor effluent, and soil extracts. The detection limit for water is 1 ug/L and 0.3 ug/g for spiked soils. Results from nearly 100 well water and bioreactor samples show excellent agreement with EPA Method 314 over the range of 1 -225 ug/L (slope = 1.11, R2 = 0.913). Some false positives were encountered in some wells. A cleanup method was developed that can eliminate false positives due to humic substances (April 2004, 26 pages).

Microbial Community Shifts Associated with RDX Loss in a Saturated and Well-Drained Surface Soil (ERDC/CRREL TR-05-4). This report was published by the U.S. Army Corps of Engineers. It reports on the microbial community composition associated with the deposited RDX under the differing soil moisture tensions. Phospholipid fatty acid (PLFA) and terminal fragment length polymorphism (T-RFLP) profiles were used to quantify the in situ microbiota. The rapid biotransformation of RDX in the saturated soil was coincident with an endpoint microbial community containing firmicutes, proteobacteria, actinobacteria, and bacteroidetes. The authors hypothesize that the saturated soil led to the development of alpha/deltaproteobacteria and firmicute subpopulations and that Tech Direct: May 1, 2005 4 of 6 clu-in.ora/newsletters ------- these populations were primarily responsible for the observed biological transformation of RDX (March 2005, 25 pages).
