Abstract: The release of toxins into the environment and the federal government’s tracking of that using the Toxic Release Inventory (TRI) compiled by the U.S. Environmental Protection Agency (EPA) are the focus of this case study, which uses GIS to explore the potential impacts of the release of such substances. The case was developed for an introductory environmental studies course.
