This video features "Science Steve" of Louisville Water Company and his animated friend Tapper explaining the importance of the Ohio River as a natural source of drinking water. He describes the river's geologic origin as a result of glaciation and the different rock layers or strata exposed when the water company dug a tunnel beside the river to access the water. The video ends with an introduction of concepts underlying this riverbank filtration system such as how an aquifer works and the meaning of the term "filtration."
