  "field": "Environment",
  "definition": "1. A two-part study that is completed before any Superfund-related remedial cleanup can begin. The first part is the Remedial Investigation, which is a study to determine the nature and extent of the contamination at the site. The second part is the Feasibility Study, which is an identification and evaluation of various clean-up alternatives. When completed, the RI/FS forms the basis for the EPA's decision as to what clean-up alternative should be selected for a particular Superfund site.\n\n2. See http://www.epa.gov/superfund/cleanup/rifs.htm. After a site is listed on the NPL, a remedial investigation/feasibility study (RI/FS) is performed at the site. The RI serves as the mechanism for collecting data, while the FS is the mechanism for the development, screening, and detailed evaluation of alternative remedial actions. The RI and FS are conducted concurrently. Data collected in the RI influence the development of remedial alternatives in the FS, which in turn affect the data needs and scope of treatability studies and additional field investigations.\n\n3. A remedial investigation is a phase in the CERCLA response process that entails an in-depth examination of the nature and extent of contamination at a site and the associated risks to human health and the environment. The feasibility study entails an analysis of remedial action alternatives comparing the advantages and disadvantages of each.",
