Project Description:<br />

Jewel Cave <strong>National</strong> Monument was established to preserve the ecosystem for its scientific interests<br />

and for public enjoyment. Contaminated runoff from a 150-space parking lot currently flows through a<br />

natural drainage area and then into passages of Jewel Cave. This project seeks to capture<br />

contaminated run-off from the parking lot and treat it prior to release. Run-off or fuel spills will drain<br />

into a large holding chamber. The contents of the chamber will be cleaned via a Smart sponge to<br />

remove hydrocarbons. This treated water will then be released back into the natural drainage areas,<br />

greatly reducing the probability of pollution entering the cave. The equipment will be buried beneath<br />

the parking lot. New drains and lines will be installed in addition to the treatment equipment. This will<br />

require redesign and an almost complete removal of the parking lot's present surface.<br />

Project Need/Benefit:<br />

In areas with caves and Karst geology, water infiltration can be very rapid. Typically the limestone<br />

bedrock of the cave formations and the caprock overlying and protecting the cave have cracks and<br />

fissures throughout their structure. Surface water enters the cave system through these cracks and<br />

fissures, with very little natural filtration to remove contaminants. A hazardous spill in the parking lot<br />

could result in miles of contaminated cave passages. The complexity and interconnectivity of the cave<br />

passages is only understood to a limited degree, but the effects of pollution in a cave are understood<br />

all too well. Fragile cave formations can be altered in form and actual existence. Jewel Cave <strong>National</strong><br />

Monument has several cave formations that are only found in this area or Jewel Cave has the highest<br />

concentration of some formations. One such formation is the very delicate Hydromagnesite Balloon. It<br />

is unknown how these form, but it is understood that even a single human breath can send them<br />

tumbling to the cave floor. Chemicals could completely destroy these formations. In most cases the<br />

damage that occurs to the cave and its geologic and biologic resources is irreversible. The asphalt<br />

surface of the present parking lot is mixing with spilled hydrocarbons (which act as a solvent) from<br />

vehicles and is becoming an additional contaminant.<br />
