Flow through the Mammoth Cave Karst aquifer can be very rapid, on the order of 1000's to 10,000's of feet per day. Contaminants entering the karst aquifer can thus be rapidly transported, unfiltered through the conduit system. The karst aquifer is very dynamic, that is, it responds nearly instantaneously to rainfall. Aquifer stage can rise tens of feet in a matter of hours, with numerous records showing stage rises of over 100 feet over the course of one day. Also, chemical and bacteriological properties of the groundwater can change dramatically following rainfall events.

Mammoth Cave is the world's longest known cave, with more than 400 miles of interconnected passages—so long that if the second and third longest caves in the world were joined together, Mammoth Cave would still be the planet's longest cave and have more than 100 miles left over!
