    GIS Link to EPA EnviroMapper

    EPA's EnviroMapper is used to view and query EPA-regulated facility information stored in the Envirofacts Warehouse. It allows the user to map several types of environmental information, including drinking water, toxic and air releases, hazardous waste, water discharge permits, and Superfund National Priorities List (NPL) sites. EnviroMapper also links to text reports, which provide even more information.

    It provides standard mapping functionality, including display, zoom, pan, and feature identification.
