On a Clear Day You Can See Forever 

In this case study, developed for an introductory environmental studies course, students grapple with the issue of air pollution, specifically the causes and effects of haze and smog as ubiquitous, persistent air quality problems that plague urban and rural areas alike. In analyzing local conditions in Minnesota, students explore the wider environmental, political, social, and human health implications of air pollution.

The Fate and Transport of Toxic Releases: A GIS Case Study

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. It would also be appropriate for use in an introductory GIS course or cartography course where some analysis is required, an introductory chemistry course for non-majors (with some more prep work on partitioning coefficients and fate and transport), or a basic soils course where remediation techniques are emphasized. The case study requires ESRI’s ArcView 3.3 software in a computer lab setting, although it could easily be adapted for use with ArcGIS 9.x.
