Nitrogen and Phosphorus Uptake in the Everglades Conservation Areas, Florida, with Special Reference to the Effects of Backpumping Runoff

Date Issued:: 1976-06
Summary:: In much of the water pumped into the northern Everglades, Florida,concentrations of inorganic nitrogen and phosphorus are relatively high. These nutrients are transported in the canals or into the peripheral marshes. Concentrations decrease sharply within 330 feet or less of the canals, whereas specific conductance remains essentially unchanged within this distance. The sharp decrease in inorganic nitrogen and phosphorus near the canal edge indicates net uptake in these shallow waters. Concentrations of nitrogen and phosphorus also decrease as water moves through the conservation areas in canals. The authors suggest that the decrease is due partly to dilution by rainfall and runoff, and partly to net uptake in the canals and their peripheral marsh.

Summary:	(DTIC Abstract): Water backpumped into Conservation Areas 1 and 3 is confined largely to canals and peripheral marshes. Water pumped into Area 2 extends into the interior marshes. Water that is backpumped into all three areas can alter water quality in the canals by breaking up water stratification,by resuspending bottom sediments, and by introducing water of a different chemical character. Concentrations of nitrogen and phosphorus decrease as water moves through the conservation areas in canals. This decrease is due partly to dilution by rainfall and runoff, and partly to net uptake in the canals and peripheral marsh. Uptake, estimated for three canals, accounted for a 2-percent decrease in phosphorus per mile and a 4-percent decrease in nitrogen per mile.
