Learn About Karst

Where is karst? Why is karst important? About 700 million people worldwide depend on groundwater in karst aquifers as their main source of water. The world's largest springs and most productive water wells flow from karst. But karst aquifers are easily contaminated and poorly understood. For example, karst groundwater pollution, in May 2000 in Canada,

Tropical karst (Chapter 15)

Introduction to karst. The word karst denotes a set of special landforms that develop mostly on carbonate rocks due to their high solubility. The rocks, however, do not dissolve uniformly, but mainly along lines of structural weakness such as joints or bedding planes. This happens both at the surface and inside the body of the rock.

The difference lies in our geology. In Wisconsin, the karst bedrock forms in dolomite, which is much less easily dissolved than the limestone that forms the karst bedrock in Florida. As a result, we have fewer and smaller voids and cavities in Wisconsin's karst. The sinkholes are proportionally smaller as well. Karst and groundwater contamination
