This newly revised issue of the Superfund Public Information System (SPIS) on CD-ROM has engineered a 'web like' configuation into its overall design scheme. The user will find it easier to travel from screen to screen through the use of button links located in the sidebar on all of the seven menus. There are also 'pop up' screens in RODS which provide definitions of the RODS data elements. Also, the record sizes in the RODS infobase have been reconstructed to include faster inquiry retrieval and flexability. Plus the CERCLIS and Archive (NFRAP) infobases display the data in convenient tables for the SPIS user. The Superfund data is a collection of three databases: Records of Decision (RODS); Comprehensive Environmental, Response, Compensation, and Liability Information System (CERCLIS); and Archive (NFRAP). Descriptions of these databases and CD contents are listed below. Data content: The CD contains the complete text of the official ROD documents signed and issued by EPA from fiscal years 1982-2004. The CD also contains 242 Explanation of Significant Difference (ESD) documents, as well as 157 ROD Amendments. RODS is the Records Of Decision System. RODS is used to track site clean-ups under the Superfund program to justify the type of treatment chosen at each site. RODS contains information on technology justification, site history, community participation, enforcement activities, site characteristics, scope and role of response action, and remedy. Explanation of Significant Differences (ESDs) are also available on the CD. CERCLIS is the Comprehensive Environmental Response, Compensation, and Liability Information System. It is the official repository for all Superfund site and incident data. It contains comprehensive information on hazardous waste sites, site inspections, preliminary assessments, and remedial status. The system is sponsored by the EPA's Office of Emergency and Remedial Response, Information Management Center. Archive (NFRAP) consists of hazardous waste sites that have no further remedial action planned; only basic identifying information is provided for archive sites. The sites found in the Archive database were originally in the CERCLIS database, but were removed beginning in the fall of 1995. The FolioViews browse and retrieval engine is used as a graphical interface to the data. Users can access simple 'canned' queries and can do complex searching on key words or fields. In addition, context sensitive help, a Superfund process overview, and an integrated data dictionary are available.
