Greener Cleanups - EPA's Methodology for Understanding and Reducing a Project's Environmental Footprint - August 10, 2011, 1:00PM-3:00PM EDT (17:00 19:00 GMT). The process of cleaning up a hazardous waste site uses energy, water, and other natural or materials resources and consequently creates an environmental footprint of its own. The US EPA is developing a methodology for evaluating the environmental footprint in order to reduce the footprint and improve the outcome of cleanup under any regulatory program. EPA will host an interactive Internet seminar to provide information about the environmental footprint assessment methodology and to obtain feedback from the environmental remediation community. This two-hour seminar will: (1) discuss the metrics for environmental footprint assessment and the methodology for estimating or quantifying the footprint; and (2) provide an interactive case study to allow participants to get a feel for the process of calculating an environmental footprint and evaluating options to reduce it. An open forum will be held after the presentations, during which participants will be able to submit questions and feedback to the speakers. For more information and to register, see .

Remediation System Evaluation (RSE), Moss-American Superfund Site, Milwaukee, Wisconsin (EPA-540-R-11-018). This document presents the results of a Remediation System Evaluation (RSE) conducted for the Moss-American Superfund Site in Milwaukee, Wisconsin. This RSE report focuses primarily on optimizing system performance, in particular addressing the stagnant groundwater zone that is limiting flow through the treatment gates and elevated COC concentrations in the vicinity of MW-34S. This report provides a brief background on the site, current operations, and recommendations for changes and additional actions. The cost impacts of the recommendations are also discussed (March 2011, 60 pages). View or download at .

Remediation System Evaluation, Colbert Landfill Superfund Site, Spokane County, Washington (EPA-540-R-11-020). The Colbert Landfill Superfund Site is located approximately 2.5 miles north of Colbert, Washington, and approximately 15 miles north of Spokane, Washington. Contaminants of concern in groundwater are specific volatile organic compounds (VOCs): 1,1,1-Trichloroethane (TCA), 1,1-Dichloroethene (DCE), 1,1-Dichloroethane (DCA), Trichloroethene (TCE), Tetrachloroethene (PCE), and Methylene Chloride (MC). There have also been low levels of 1,4-Dioxane observed in groundwater. The groundwater remedy includes a pump-and-treat (P&T) system as well as components of landfill post-closure (e.g., landfill cap, landfill gas system) that serve to reduce contaminant source loading to groundwater over time. The remedy has also included the provision of an alternate water supply to impacted residents plus institutional controls. The RSE provides an opportunity for an independent third-party review of these remediation efforts (October 2010, 80 pages). View or download at .

Streamlined Remediation System Evaluation, Wash King Laundry Superfund Site, Pleasant Plains Township, Michigan (EPA-540-R-11-019). The Wash King Laundry site was placed on the National Priorities List of Superfund sites in 1983. The Remedial Investigation/Feasibility Study (RI/FS) process, lead by the Michigan Department of Natural Resources, began in September 1988 with an emphasis on data collection and site characterization. The Record of Decision was signed in March 1993, followed by an Explanation of Significant Differences in June 1996, and a remedy design thereafter. Remedy implementation began in June 1999 and included building demolition, tank removal, installation of a pump and treat (P&T) system, and installation of a soil vapor extraction (SVE) system. The P&T system and SVE system were fully operational in April 2001. In July 2009, the site contractor provided a work plan for implementing in-situ bioremediation of the groundwater and saturated soils in the vicinity of the former Wash King Laundry facility. In-situ bioremediation began in January 2010.This RSE-lite focuses on all aspects of site remediation including the P&T system, SVE system, in-situ bioremediation, and site-wide monitoring program (February 2011, 55 pages).
