Hydro-geology, Water Quality and Land Management in the Big Spring Basin, Clayton County, Iowa, June 1983

摘要

The Big Spring study was designed to provide a controlled assessment of a karst groundwater basin. This allows a more thorough understanding of the groundwater quality, the processes resulting in groundwater degradation, andudevaluation of possible control measures or management practices. The Big Spring area was chosen because: 1) prior knowledge of the groundwater system in the Galena aquifer existed; 2) ICC and SCS had specific concerns with water-quality and landuse in the area; and 3) the ICC Fish Hatchery at Big Spring allowed the direct measurement of groundwater discharge from the basin,udwhich is generally impossible in other areas.
