Few people know about the underground world that exists beneath Bowling Green, where water can flow in underground rivers in what is known as a karst landscape. In karst areas, water is especially vulnerable to pollution. In fact, did you know what we do on the surface in Bowling Green directly impacts both the water below ground and our drinking water? This is possible because a portion of the water feeding the Barren River, from which the City draws its drinking water, flows through underground karst networks. This is possible because a portion of the water feeding the Barren River, from where our drinking water is drawn, flows through underground karst networks before reaching the surface.
