Book excerpt: The conduct of a feasibility study (FS) under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) is accomplished in two steps. The first step, the Development and Screening of Alternatives (DSA), involves identifying and screening a broad selection of alternatives that achieve the Remedial Action Objectives (RAOs). These RAOs are listed in Table ES 1.0-1. The range of more promising alternatives retained following screening in the DSA then undergoes an in-depth evaluation during the second step of the FS, the Detailed Analysis of Alternatives (DAA). The objectives of the DAA include the following: Provide a more detailed definition of each alternative retained in the DSA, as necessary, with respect to the volumes or areas of contaminated media to be addressed, the technologies to be used, and any performance requirements associated with those technologies; Assess each alternative against the DAA evaluation criteria identified in the National Contingency Plan (NCP) and defined in U.S. Environmental Protection Agency (EPA) guidance (EPA 1988); Perform a comparative analysis among the alternatives to evaluate the relative performance of each alternative with respect to each evaluation criterion; Select a preferred alternative for each medium group based on the comparative analysis.
