Karst bedrock allows relatively unfiltered water (and possibly contaminants) to quickly recharge the groundwater aquifers. The water flows through underground channels formed via dissolved conduits or fractures. Northeast Wisconsin and the Door County peninsula have a lot of karst bedrock features, which impacts how contaminants can move through systems. The complexity of karst systems can be confusing, but a visual illustration can help in explaining these features. Using a guide developed by Caroline Rose and Mike Parson, Logan Maedke constructed a physical model to illustrate groundwater movement through karst conduits using XPS foam insulation boards, waterproof sealant, and acrylics. This model will act as a starting point in order to develop a more complex model in the near future to be used as an “on-the-road” model for teaching and outreach.
