PULS, R. W. LONG-TERM PERFORMANCE OF PERMEABLE REACTIVE BARRIERS: LESSONS LEARNED ON DESIGN, CONTAMINANT TREATMENT, LONGEVITY, PERFORMANCE MONITORING AND COST-AN OVERVIEW. Presented at Nato Programme Security through Science Advanced Research Workshop, Krakow, POLAND, June 27 - July 01, 2005.
Impact/Purpose:
To inform the public.
Description:
This presentation will provide an overview of permeable reactive barrier performance for field sites in the U.S. evaluated over the last 10 years by the U.S. Environmental Protection Agency's Office of Research and Development (EPA-ORD) in collaboration with other U.S. federal agencies, consulting companies and academic institutions under activities sponsored by the EPA's Remedial Technology Development Forum (RTDF). The RTDF is a public-private partnership which undertakes research, development, demonstration, and evaluation efforts focused on finding innovative solutions to high priority environmental problems. Recent synthesis reports have been published which summarize performance evaluation and cost for PRB applications and research for the last 10 years. The focus of the presentation will be on the effectiveness of these systems for plume capture and contaminant degradation/immobilization, microbiological and geochemical impacts on reactivity and longevity, and cost. In addition to conclusions and recommendations, the presentation will pose questions and challenges for future research, development and application of this important remedial technology.
