Evaluation of Remedy Resilience at Superfund NPL and SAA Sites

The Office of Superfund Remediation and Technology Innovation (OSRTI) prepared this report to continue its effort to determine how resiliency measures are considered in conceptual site models, remedy system designs and operations, and how resilience is built into remedies at National Priority List (NPL) sites and sites with Superfund Alternative Approach agreements. Following a very active hurricane season in 2017, EPA sought to gather information on the performance of remedies in areas recently impacted by Hurricanes Harvey, Irma and Maria. This effort was a “desktop analysis”, gathering information from existing sources, such as the Superfund Enterprise Management System, media, site reports, etc., and where needed by contacting remedial project managers (RPMs).
