Hydrologic conditions in Broward County, Florida, 1976

During the 1976 water year, rainfall was 3.6 percent below average in Broward County, Fla. Water levels in the Pompano Beach and Dixie well fields were lower during the peak of the 1976 dry season than the peak of the record low dry season in 1971. Flow in the major canals was variable during the 1976 water year compared to 1962-75 averages. Flows in Cypress Creek, Middle River, and Snake Creek at S-29 were higher than the average. Flows in Plantation Canal and South New River were equal to the 1962-75 averages, while Hillsboro, North New River, and Snake Creek at N.W. 67th Avenue were below the long-term averages. The concentrations of principal mineral constituents in surface water in Broward County were within limits established by Florida State Water Standards, with the exception of iron at one station. Total coliforms were equal to or within permissible limits for class III water and waters for public supply in Broward canals at all sites during the 1976 water year. Fecal coliform did not exceed the permissible limit for public water supply at any of the sites during the 1976 water year. (Kosco-USGS)

Quality of the water in Borrow Ponds near a major highway interchange, Dade County, Florida, October-November 1977

Water, bottom sediment, and aquatic plants were sampled from ponds near a major south Florida highway interchange to document concentrations of selected constituents in an aquatic environment near heavy vehicular traffic. Generally, concentrations of constituents were within the range expected in an uncontaminated environment in south Florida. However, concentrations did exceed south Florida background levels or Environmental Protection Agency criteria in a few cases. Two trace elements--chromium (20 micrograms per liter) in ponded surface water and lead (500 micrograms per gram) in bottom sediment--exceeded background levels. Concentrations of dieldrin (22 micrograms per kilogram) and polychlorinated biphenyls (53 micrograms per kilogram) also exceed background levels in bottom sediment. The concentration of phenol (23 micrograms per liter) in ground water exceeded Environmental Protection Agency quality criteria by 22 micrograms per liter, but was within the background range for south Florida. Ten metals were detected in the cattail or algal samples, but only iron, manganese, and zinc were in higher concentrations than those in the bottom sediment. (Woodard-USGS)

Record of wells in the Floridan aquifer in Dade and Monroe counties, Florida

The utilization of the Floridan aquifer as a source of potable water has increased. The use of the Floridan aquifer for subsurface storage of freshwater, and as an industrial water supply in Dade and Monroe Counties, is being considered by water management authorities and some industries. Information on locations, depths, casings, and year drilled for 67 wells that penetrate the Floridan aquifer in Dade and Monroe Counties is presented to assist in planning future uses of the Floridan. Chloride concentrations in water from wells ending in the Floridan aquifer in Dade County ranged from 1,200 to 9,000 milligrams per liter. In Monroe County the chloride concentrations ranged from 1,600 to 20,000 milligrams per liter. Water levels were measured in selected wells to determine the altitude of the potentiometric surface. The measurements indicate that the 40-foot potentiometric line extends from southern Dade County to the upper Florida Keys.

Summary of hydrologic data collected during 1975 in Dade County, Florida

During the 1975 calendar year rainfall in Dade County, Fla., was 14.89 inches below the long-term average (57.17 in.). Ground-water levels ranged from 0.1 foot above to 1.1 feet below average. The highest and lowest ground-water levels for the year were both 1 foot below their long-term averages. In the Hialeah-Miami Springs area, ground-water levels in wells near the centers of the heaviest pumping ranged from 9.8 to 11.2 feet below mean sea level and in the Southwest well field area, ground-water levels near the centers of pumping ranged from 3.5 feet above to 3.4 feet below mean sea level. The combined average daily discharge from eight major streams and canals that flow into Biscayne Bay was 1,014 cubic feet per second (cfs), 124 cfs above the combined average daily flow for the 1974 water year. The combined average daily flow through the Tamiami Canal outlets was 568 cfs, 202 cfs below that of the 1974 water year. The position of the salt front in 1975 in the coastal part of the Biscayne aquifer was about the same as in 1974 except at Miami International Airport and Homestead Air Force Base where the salt front had encroached farther inland.
