ABSTRACT
Karst Terrain with characteristics of relief and drainage arising from a high degree of rock solubility in natural waters. The majority of karst occurs in limestones, but it may also form in dolomite, gypsum, and salt deposits. Features associated with karst terrains typically include: irregular topography, sinkholes, vertical shafts, abrupt ridges, caverns, abundant springs, and disappearing streams. Karst aquifers are associated with karst terrain (EPA-40CFR300-AA).
