The most interesting aspect of a karst landscape is its unique hydrologic system. Karst landscapes are primarily underlain by carbonate, primarily limestone and dolomite, where surface water and groundwater are interconnected to form one functional unit. The end result of this hydrologically integrated flow system is the karst spring. Springs provide substantial quantities of water for human consumption and commercial enterprises. Because karst aquifers provide effective natural cleansing, it is imperative to understand the dynamic flow systems within these aquifers to protect these vulnerable water supplies from contamination.
