Effects of Land Use on Surface-Water Quality in the East Everglades, Dade County, Florida
Water-Resources Investigations Report 81-59
Bradley G. Waller
Water-quality characteristics were determined at five developed areas in the East Everglades, Dade County, Florida, during the 1978 wet season (June through October). These areas are designated as: Coopertown; Chekika Hammock State Park; residential area; rock-plowed tomato field; and Cracker Jack Slough agricultural area. Data from the developed areas were compared with data from four baseline sites in undeveloped areas to determine the effects of land use on the surface-water quality.
The rock-plowed tomato field was the only area where surface-water quality was affected. Water quality at this field is affected by agricultural activities and chemical applications as indicated by increased concentrations of orthophosphate, organic nitrogen, organic carbon, copper, manganese, mercury, and potassium.
The remaining four areas of land use had water-quality characteristics typical of baseline sites in nearby Northeast Shark River Slough or Taylor Slough.
of soil indicated chlorinated-hydrocarbon insecticide residues at Coopertown
and the two agricultural areas, Cracker Jack Slough and the rock- plowed tomato
field. Trace elements in concentrations greater than base level occurred at
both agricultural areas (manganese), Chekika Hammock State Park (manganese),
and at Coopertown (lead and zinc).
