DRAFT Figure 2-21. Temporal trend of specific conductance and salinity in the Sulphur Springs Pool. Kendall-Theil slope shown. 2 - 23
DRAFT In comparison to specific conductance values of other Floridan aquifer wells in the area, the observed values at Sulphur Springs and the Tourist Club well are anomalously high. Data are somewhat limited in recent years, but for the year 2000, specific conductance is on the order of 15,000 µmhos/cm for the Tourist Club well and around 3,000 µmhos/cm for the spring. Three monitor wells located within 3 miles (4.8 km) or less of the spring had specific conductance values of 390, 550, and 993 µmhos/cm. This evidence points to local upconing at the spring of more mineralized water, presumably flowing along preferential fractures. The City of Tampa has sponsored diver explorations of the cave system that contributes flow to Sulphur Springs (Figure 22-B on the following page). These investigations have found that the passage that flow from the Alaska tunnel has much higher specific conductance than flow from the Orchid tunnel (Figure 2-22A). The specific conductance seen at Sulphur Springs is the result of the mixing of both water sources (Schreuder Inc. 2004). Figure 2-22A. Specific conductance in the Sulphur Springs cave system on November 15, 1998. Adapted from Schrueder, Inc. Used with permission of the City of Tampa. 2.5.2.1 Effects of gate operations and withdrawals on specific conductance The manipulation of water levels in the spring pool can affect the water quality of the spring discharge. When water levels in the pool are lowered by opening the gate at the outlet structure, specific conductance values in the pool typically increase. Figure 2-23 is a plot of average daily values for gage height and specific conductance in the spring pool for the period of 1999 through 2002. Those days when the gage heights are below approximately 2 ft. represent times when the pool was manually lowered for maintenance purposes. Prolonged periods of gate openings and corresponding low water levels occurred during 1999 – 2000 and much shorter intervals in 2000 and 2002. 2 - 24
