“…39), which is the source of water supply for more than 3 million people in Miami-Dade, Broward, and Palm Beach Counties. Total withdrawals from the aquifer were about 870 Mgal/d in 1995 (Marella, 1999); withdrawals from the aquifer in Miami-Dade County alone (550 Mgal/d) were greater than any other county along the Atlantic coast. The Biscayne aquifer underlies an area of about 4,000 mi 2 and extends beneath Biscayne Bay, from which its name was derived, and the Atlantic Ocean.…”

“…Ground-water withdrawals from the aquifer system in the three northeastern-most coastal counties of Florida alone were 217 Mgal/d in 1995 (Marella, 1999). These withdrawals have caused long-term water-level declines in several areas of the region; in northeastern Florida, for example, water levels in the Floridan aquifer system have declined during the past 50 to 60 years at an average rate of about one-third to one-half foot per year (Spechler, 1994(Spechler, , 2001).…”

An accurate inventory of irrigated crop acreage is not available at the level of resolution needed to better estimate agricultural water use or to project future water demands in many Florida counties. A detailed digital map and summary of irrigated acreage was developed for Polk County, Florida, during the 2016 growing season. This cooperative project between the U.S. Geological Survey and the Office of Agricultural Water Policy of the Florida Department of Agriculture and Consumer Services is part of an effort to improve estimates of water use and projections of future demands across all counties in the State. The irrigated areas were delineated by using land-use data provided by the Florida Department of Agriculture and Consumer Services, along with information obtained from the South and Southwest Florida Water Management Districts consumptive water-use permits. Delineations were field verified between April and December 2016. Attribute data such as crop type, primary water source, and type of irrigation system were assigned to the irrigated areas.The results of this inventory and field verification indicate that during the 2016 growing seasons (spring, summer, fall, and winter), an estimated 88,652 acres were irrigated within Polk County. Of the total field-verified crops, 83,995 acres were in citrus; 2,893 acres were in other non-citrus fruit crops (blueberries, grapes, peaches, and strawberries); 621 acres were in row crops (primarily beans and watermelons); 1,117 acres were in nursery (container and tree farms) and sod production; and 26 acres were in field crops including hay and pasture. Of the total inventoried irrigated acreage within Polk County, 98 percent (86,566 acres) was in the Southwest Florida Water Management District, and the remaining 2 percent (2,086 acres) was in the South Florida Water Management District.About 85,788 acres (96.8 percent of the acreage inventoried) were irrigated by a microirrigation system, including drip, bubblers, and spray emitters. The remaining 3.2 percent of the irrigated acreage was irrigated by a sprinkler system (2,360 acres) or subsurface flood systems (504 acres). Groundwater was the primary source of water used on irrigated acreage (88 percent, or 78,050 acres); the remaining 10,602 acres (12 percent) used groundwater combined with surface water as the irrigation source.

“…Specifically, the nuisance growth of filamentous algae may be associated with increased nitrate concentrations and were identified as a problem for recreational use and aquatic life support in springs (Stevenson et. al., 2004 (Marella, 2004). Ground water use is projected to increase about 60 percent by the year 2025 due to projected population increases for the area (St. Johns River Water Management District, 2006b).…”
