| Abstract |
|
Preparation of an environmental impact statement (EIS) is the organizational focus for an undergraduate lab course in environmental chemistry. Students work collaboratively through the semester to prepare an EIS following National Environmental Policy Act (NEPA) guidelines. This involves several stages of activity including a scoping process, field sampling, and laboratory analyses, modeling of the results to predict impacts, and report writing. To maximize student interest and make sampling practical, the proposed activity for which the EIS is prepared is locally based. Laboratory analyses are performed using the U.S. EPA's standard methods for turbidity, color, coliforms, nutrients, trace metals, alkalinity, petroleum hydrocarbons, and chlorinated pesticides. The completed EIS is defended in a mock public hearing at which students play assigned roles. In addition to requiring a high degree of group work, this approach emphasizes the interdisciplinary nature of environmental chemistry and the difficulty of using scientific data to perform risk assessments. Preparation of an EIS is a federal or state requirement for many construction projects and hence students get a chance to experience a potential career area as well as acquire a marketable skill.
