摘要

Municipal water demand in Volusia County, Florida, is expected to more than double from 45.7 million gallons per day (mgd) in 1988 to 95 mgd by 2010 (Williams 1997). Most of this increase is from the Daytona Beach metropolitan area. The communities in this area have had to abandon or reduce pumpage from their old wellfields near the coast due to saltwater intrusion and have had to develop new wellfields inland, primarily west of Interstate 95 (I-95) along the Rima Ridge. Tiger Bay lies on the west side of Rima Ridge and Bennett Swamp lies along the east side. St. Johns River Water Management District (SJRWMD) has identified the Daytona Beach wellfield drawdown area as having a moderate-to-high likelihood of harm to native vegetation (Vergara 1994). Tiger Bay also has been identified by the U.S. Geological Survey (USGS) as a potential recharge area in the event that well pumpage lowers the head of the Floridan aquifer (Rutledge 1985). Surface drainage (Tiger Bay Canal and Thayer Canal) has also contributed to the drop in the surficial water table.
