Revegetation and Restoration of an Oil Contaminated Wetland in Northern New Jersey - January 19. 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 .

NIEHS DNAPLs - Biological Remediation Processes - January 25. This seminar is the fourth in a series sponsored by the NIEHS Superfund Basic Research Program to present current research on DNAPLs contaminated sites. The seminar will summarize a comprehensive literature review on the microbial degradation of chlorinated solvents. Chlorinated solvents such as chlorinated ethenes, ethanes and methanes are important priority pollutants of groundwater. Diverse strategies are utilized by microorganisms in the degradation of organochlorine compounds ranging from reductive dehalogenation, hydrolytic to oxygenolytic release of chloride. To understand how microorganisms gain energy and benefit from biodegradation of chlorinated solvents, one must consider biodegradation as a redox reaction in which an electron donor becomes oxidized at the expense of an electron acceptor. In addition to the discussion of bioremediation processes, the session will also discuss advances in phytoremediation techniques for important toxicants at hazardous waste sites. For more information and to register, see http://clu-in.org/studio .

ITRC Environmental Management Planning on Active Small Arms Firing Ranges - January 26. The training uses a logic diagram to describe the appropriate steps an environmental professional or range manager should use to establish an operational understanding of a range and the impact it can have on the environment if left unattended. It assists the user to define the environmental characteristics at a range that could potentially impact the environment and lists the appropriate questions that range operators should ask when evaluating the potential for environmental impact. The training briefly describes a variety of new and conventional technologies and techniques (i.e., best management practices) available to prevent environmental impact on the range.

Deployment of Phytotechnology in the 317/319 Area at Argonne National Laboratory-East (EPA/540/R-05/011). This EPA report discusses the accomplishments of a phytotechnology system deployed by ANL-E in the 317/319 Area to reduce the risks from the VOCs and tritium. The EPA Superfund Innovative Technology Evaluation Program (SITE) and ANL-E evaluated the demonstration for a three-year period (1999-2002). The effectiveness of the various plantings was monitored directly through groundwater and soil measurements and samples, and indirectly via plant tissue analysis, microbial surveys, geochemical analysis, soil moisture probes and sap flow monitoring. ANL-E predicted physical effects of the plants on groundwater using a standard hydrological model. The treatment period will continue for up to 20 years. This Innovative Technology Evaluation Report presents the results from sampling, monitoring, and modeling efforts to date. The project has demonstrated success in reducing contaminated groundwater flow and taking up contaminants at the source; it also provides insight into the techniques that are useful for measuring and predicting the effectiveness of future similar projects (December 2003, 88 pages).

Streamlined Remediation System Evaluation for a Ground Water Pump and Treat System for Chemko Technical Services, Inc. Facility (EPA 542-R-05-018) Streamlined Remediation System Evaluation for a Ground Water Pump and Treat System for Englehard Corporation Facility" (EPA 542-R-05-026). Two recent remedial system evaluations were completed and the recommendations captured. A Remedial System Evaluation involves a team of expert hydrogeologists and engineers, independent of the site, conducting a third-party evaluation of a ground water pump and treat system or other remedy of environmental contamination. It is a broad evaluation that considers the goals of the remedy, site conceptual model, above-ground and subsurface performance, and site exit strategy. The evaluation includes reviewing site documents, communicating with the site team, and compiling a report that includes recommendations to improve the efficiency and effectiveness of the remedy. Recommendations with cost and cost savings are provided in the following four categories:
Improvements in remedy effectiveness; reductions in operation and maintenance costs; technical improvements; and gaining site close-out. To see these two studies and many others, see http://clu-in.org/optimization .
