What is CLEAN Environmental Science Education?

The Shane Hulsey CLEAN Environmental Program provides students from third grade through college with hands-on environmental education activities while they safely participate in a canoe trip, stream walk, or volunteer service-learning restoration project. Since 1996, the CLEAN program has safely taken over 38,500 Alabama students to the Cahaba River. Through our CLEAN Virtual Learning Resource Library, we are bringing these valuable learning resources to an even wider audience by making them accessible online.

Fight Pollution

How Does Litter end up in Your River Series:

The Cahaba River is one of the most biologically diverse rivers in north America. Running through the heart of Alabama, it passes through some of the state’s most populated areas. This leaves it vulnerable to many types of pollution, including litter. Most of the trash in the Cahaba River, your drinking water source, and in lakes, other rivers, and the ocean starts on land where it is carried into waterways by rain and wind.
