This report summarizes a variety of significant projects that ETSC and its colleagues in the Land Remediation and Pollution Control Division (LRPCD) have supported during the last five years. Projects have addressed an array of environmental scenarios, including 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 the construction and testing of pilot projects and new technologies. As such, ETSC also organizes and reports significant developments in environmental engineering. In some cases, the team has gone into the field to spearhead projects that are at the cutting edge of remediation activities. 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 remains a central focus, the team is reaching out to support other efforts that will directly prevent the problems ETSC seeks to resolve. LRPCD and ETSC have evolved continually to meet the demands, as well as scientific and engineering needs, of the program offices and regional personnel.
