The following case study was prepared by the Brownfields Technology Support Center (BTSC), within the U.S. Environmental Protection Agency's (EPA) Office of Superfund Remediation and Technology Innovation (OSRTI). The case study was developed as part of EPA's ongoing initiative to promote the use of an integrated Triad approach to limit decision uncertainty at hazardous waste sites through the use of sound science. The Triad approach, which consists of systematic planning, dynamic work strategies, and real-time measurement technologies that include field-based analyses, is being promoted by OSRTI and its partners as a viable method for streamlining site investigations. The Cos Cob Power Plant site is located in the southeastern corner of Connecticut, and is adjacent to Cos Cob Harbor. The site was the location of a former power plant, which has since been demolished. The current owner of the site is the Town of Greenwich, Connecticut. The town plans to reuse the site and has received a Targeted Brownfields Assessment (TBA) grant to assess potential reuse options. Reuse alternatives proposed for the site include creation of a walking trail and wetlands and a series of playing fields. EPA Region 1 requested assistance from the BTSC in an attempt to maximize the efficiency of the TBA by applying the Triad approach. A scoping meeting was held between EPA region 1 and the BTSC during November of 2002. This initial planning meeting discussed a revised approach to site characterization that would rely on the use of field-based measurement technologies and the Triad approach.
