More recently, the author delivered this course in the contextof Air Quality, where the projects often involved the design of air cleaner systems or aerosollaboratory instrumentation. In 2005, the School of Engineering conducted a major re-structuring of IED and a renewedemphasis on hands-on projects was implemented. This new focus on project-based learning is inaccordance with trends around the country 1. The first author embraced some of the recentchanges to the course and adopted additional ones to tailor the needs of the EnvironmentalEngineering majors.

Conventional methods of drinking water,waste water, and air pollution treatment are now the focus of attention in the revised EnvEcourse. The primary goals of the EIA course are to engage all CE students regardless of theirspecialization, and create an interdisciplinary forum to discuss and evaluate some of the social,economic, and environmental issues associated with CE projects.

The students have studied groundwater remediationtechniques and are tasked in a final class project to conduct a pilot study to determine ifbiodegradation of contamination at the Ft. Campbell site is significant. This project requiresstudents to perform a tracer study on the bench-scale karst system and then use thebiodegradation rate data from a separate study to predict the extent of biodegradation in thebench scale system. Then a field study is done with a conservative tracer to establish residence-time distribution in the karst aquifer (photo 3). Last, the students use their model to determinethe amount of biodegradation that
