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.gov/superfund/25anniversary .

New Documents and Online Resources

Environmental Management at Operating Outdoor Small Arms Firing Ranges (SMART-2). 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 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).

Field Screening Method for Perchlorate in Water and Soil (ERDC/CRREL TR-04-8). 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 these populations were primarily responsible for the observed biological transformation of RDX (March 2005, 25 pages).
