This seminar presents a systematic approach for the evaluation of capture zones at pump and treat systems, and provides an overview of a recently published USEPA document on the topic (EPA 600/R-08/003, January 2008). The target audience is project managers who review those analyses and/or make decisions based on these types of analyses. This course will highlight: the importance of capture zone analysis during ground water remediation, particularly for sites requiring containment; key concepts of capture, such as "target capture zones" and "converging lines of evidence;" and typical errors made in capture zone analysis. Examples will be used to demonstrate key aspects of capture zone analysis. For more information and to register, See http://clu-in.ora/studio . ITRC Perchlorate Remediation Technologies - October 9.

The Superfund Basic Research Program (SBRP), in collaboration with the Environmental Protection Agency (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI) presents "Phytoremediation." This series of online seminars will focus on the science of incorporating phytoremediation into hazardous waste site remediation plans. Dr. David Tsao, BP Corporation North America, Inc., will provide an overview of phytotechnologies, a broad set of technologies that utilize plant-derived processes to remediate or contain contaminants in soil, sediments, surface, or groundwater. Dr. Tsao will also touch on the limitations that need to be considered when evaluating the use of phytotechnologies for site-specific applications. Dr. Jerald Schnoor, SBRP-University of Iowa, will focus on TechDirect: October 1, 2008 1 of 5 clu-in.ora/newsletters ------- plant degradation of airborne PCB congeners, a potential in situ treatment PCBs in soils and groundwater. Dr. Schnoor will describe the green liver model, which explains the fate of organic contaminants inside plant tissues, and will focus on the three phases of PCB metabolism. He will also introduce poplar experiments designed to confirm which genes are responsible for PCB metabolism as well as studies that identify endophytic bacteria and rhizosphere microorganisms that increase the rate of PCB degradation.

Green Remediation: Opening the Door to Field Use Session A (Introduction and Carbon Calculus: A RCRA Case Study) - November 24. In July, EPA held its annual National Association of Remedial Project Managers meeting in Portland, OR and one of our most attended sessions was on Green Remediation (GR). Because of its success, members of EPA's Technical Support Project, led by the Engineering Forum, have taken this full-day session and are bringing back a number of the same talks as online seminars this fall and winter. There will be three sessions, each 1.5 hours long. EPA's definition of GR includes the practice of considering the environmental effects of a remediation strategy (i.e., the remedy selected and the implementation approach) early in the process, and incorporating options to maximize the net environmental benefit of the cleanup action.Some practices are quite "mature," such as construction site best management practices including stormwater runoff management and construction and demolition (C&D) debris recycling. Others are still emerging, including the use of renewable energy sources such as wind and solar to power remedial systems. Over the three sessions, the online training will introduce you to the key technical, policy, and application aspects of GR.

The California Department of Toxic Substances Control (DTSC) has released a new guidance document that presents an option for expediting and encouraging cleanup of sites with elevated concentrations of metals in soil. The guidance is applicable on a case-by-case basis to operating and closing hazardous waste facilities and Brownfields sites. The approach streamlines the cleanup process by (1) limiting the number of evaluated technologies to two cleanup alternatives: excavation/disposal and containment/capping; (2) providing guidance for establishing background concentrations, screening levels, and cleanup goals; and (3) providing resources that facilitate remedy implementation, documentation, and administrative processes.

New Documents on EUGRIS, the platform for European contaminated soil and water information. More than 28 resources, events projects and news items were added to EUGRIS 1 - 24 September, 2008. These can be viewed at httn://www.eunris.info/whatsnew.asn. Then select the appropriate month and year for the updates in which you are interested. The following reports were featured on EUGRIS: Contaminated Land Exposure Assessment (CLEA) software (2008). This software, CLEA software version 1.03 beta, is a computer version of the CLEA model. It replaces TechDirect: October 1, 2008 3 of 5 clu-in.ora/newsletters ------- CLEA UK, the previous version of the software. You can use the CLEA software to derive generic soil assessment criteria using generic assumptions about the characteristics of contaminants and people likely to be present on site; derive site-specific soil assessment criteria by entering your own data on the characteristics of contaminants and people likely to be present on site and/or using a non-generic approach; and assess whether a measured concentration in soil (and where available, measured site concentrations for contaminants within soil air, ambient and indoor air, and fruits and vegetables) would present a potential risk to human health for a particular set of circumstances.
