This report highlights significant projects that the ETSC has supported throughout fiscal year 2014. Projects have addressed an array of environmental scenarios, including but not limited to remote mining contamination, expansive landfill waste, sediment remediation by capping, and persistent threats from abandoned industrial sites. A major component of affecting meaningful remediation lies in constructing and testing new, innovative treatment technologies through pilot and field research. For example, ETSC teams have gone into the field to spearhead projects that are at the cutting edge of remediation research in the areas of bioremediation and ground water treatment, active sediment capping, in-situ stabilization, and sustainable site cleanup. ETSC organizes and reports significant developments in environmental engineering in the form of Engineering Issue Papers and peer-reviewed journal publications. ETSC has also taken on a selection of newer initiatives that focus on integrating sustainability into communities and land use plans. While ETSC's principal mission of bolstering technical expertise for site-specific remediation at contaminated sites remains a central focus, ETSC teams are reaching out to support other efforts in prevention thereby reducing EPA’s burden from legacy sites in the future. NRMRL/LRPCD and the ETSC have evolved continually to meet the demands, as well as scientific and engineering needs of the EPA program offices and regional clients.
