Watershed and Pollution Impact Assessment

Cassie from the Austin Watershed Protection Department introduces a watershed model, explaining its components like the Colorado River and aquifer layers. She presents a pollution scenario involving a character named Sally, who accidentally spills oil, leading to a discussion on pollution's impact on watersheds. The video includes a hypothesis test to determine the pollution's effect on local water bodies. Cassie concludes by emphasizing the importance of reducing pollution and invites viewers to explore additional resources and activities.
