The geology of Kentucky varies dramatically depending on where you are in the state. Be it clay, sand and gravel in the Jackson Purchase Region, sandstone and coal in western and eastern Kentucky, or limestone in central Kentucky, the geology of the area can have a direct impact on the quality and quantity of groundwater.
Kentucky is well known for its karst features. Approximately 55% of the state is underlain by rocks that could develop karst terrain (sink holes, sinking streams, caves, and springs). Water wells also intersect karst features. Click here to view karst related videos.
