Description
Coldwater Cave, located in Decorah, Iowa is surveyed to contain 17.2 miles of passageways. This study is a mapping of how dissolved oxygen levels and water conductivity compare throughout water samples taken at 9 different locations within the cave. In this study we want to know how what is on the surface is impacting the cave water quality as Coldwater Cave sits between two above ground rivers and is covered with land used for agricultural purposes. Water quality studies done on other major rivers have shown that typical conductivity levels are within the 200-1000 micro-Siemen/cm range, and it is important to determine whether the cave water still fits into that same range with the watershed and agricultural influences. Studies have also shown that typical healthy water samples contain DO of between 80-120%, so expected values will be closer to the lower end of that spectrum based on the low oxygen levels in the cave air as determined in previous cave air quality studies.
