Mammoth Cave, appropriately named, is the longest known cave system in the world. This 365-mile natural underground phenomenon draws more than two million curious visitors each year. Explorers come not only to wander through the cave's dark chambers and complex labyrinths, but also to enjoy an extremely diverse population of animal and plant species - some endangered - that make their home above ground in the forests, rolling hills and rivers of this Kentucky-based U.S. National Park.
Protecting the treasured wildlife and abundant natural resources of Mammoth Cave National Park is the main goal of the U.S. National Park Service. Keeping groundwater clean is fundamental to this effort. In 1984, the National Park Service installed two wastewater stabilization ponds to treat domestic wastewater that flows from the Great Onyx Job Corps Center, a vocational training facility located on the grounds of the park. Operating in series, the primary treatment pond measures 190 feet by 200 feet and the polishing pond measures 300 feet by 200 feet. Once treated, the effluent from the ponds is released into the Nolin River, a tributary of the Green River, which also runs through the park. Both rivers are favored recreation destinations for Mammoth Cave visitors and other outdoor enthusiasts.
