Determining the influence of surface water on Six Mile Spring, Parawan, Utah: Abstract

Sue A. Finstick


Six Mile Spring has historically been the main source of culinary water for the City of Parowan, Utah, providing about 900 gpm year-round. Routine water sampling indicated a possible link with surface water. Tests were undertaken to determine the influence of surface water on the spring. The results of additional water sampling, as well as the results of a Hydrolab Datasonde 3 logger, a MicroParticulate Analysis (MPA) test, and a calcium chloride tracer test, were inconclusive. A dye tracer test (Fluorescent FWT Red) proved conclusively that Six Mile Spring is under the direct influence of surface water. Geologic mapping indicates that the spring is fault-controlled. However the surface water influence is likely a result of solution channels within the Tertiary (Eocene and Paleocene?) Claron Formation limestone. Future plans call for similar testing on other springs in the area.
