Sulphur Spring boil
Sulphur Spring is a fourth-magnitude spring, formerly known as Camp Spring. A large sand boil about 5 feet wide discharges into an oval-shaped spring pool about 70 feet long and 15 feet wide. The bottom of the pool is covered with organic debris, except at the spring boil. The water is clean and clear, with a strong sulfur odor. The spring run flows east about 0.5 mile to Rock Springs Run.
Discharge at Sulphur Spring was measured by the U.S. Geological Survey (USGS) in 1995 and 1997. St. Johns River Water Management District measured discharge twice in 2003, before and after mitigation work at the spring. The mean and median discharges for the period are 0.74 cfs and 0.79 cubic feet per second, respectively (see the table below).
Sulphur Spring was sampled by USGS in 1997 and 1999. Summary statistics of the water quality data for selected variables are shown in the table below.
