Use of Geographical Information System (GIS) is common today in large-scale environmental remediation activities. At those sites that are covered by the federal Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), or Superfund, the US Environmental Protection Agency (EPA) typically establishes a GIS database in the process of preparing its Remedial Investigation/Feasibility Study (RI/FS). This database is linked to geographical information so investigators can visualize the physical extent of contamination and make better judgments in developing proposed solutions. Also, when linked with contaminant transport models, the GIS enables EPA and contractors to model the likely results of various remediation remedies. After cleanup is well underway, the GIS continues to serve a useful purpose by storing and displaying in-progress information in the database, allowing reviewers to monitor the effectiveness of the chosen remedy. This presentation describes how environmental information contained in EPA`s GIS database has been linked to GISs established by local municipalities for one of the largest Superfund sites in the country--the San Gabriel Valley Groundwater Basin. Parsons Engineering Science, Inc. combined these databases in support of an Environmental Impact Report for the water delivery component of this project. The paper also describes how the combined GIS has enabled the cleanup project to proceed in a way that is sensitive to local concerns.
