UF scientists to probe downstream ecological impacts of stormwater ponds
GAINESVILLE — Florida teems with rain. Depending on where you live, you might get 40 to 60 inches annually. That rain must go somewhere. Enter Florida’s 76,000 stormwater ponds. When it rains, the water runs off the land, bringing chemicals, grass clippings, lawn debris and more from the landscape into these ponds.
Yet little to no research analyzes downstream ecological impacts from those ponds. Stormwater ponds were originally designed to reduce downstream flooding and are expected to provide water quality benefits by preventing things like sediments or nutrients from entering natural water bodies.
Although ponds do help water quality, research has shown that ponds aren’t as good at removing nutrients such as phosphorus and nitrogen as they were originally designed. Nutrients not removed by the ponds might go from the stormwater pond – which collects the rain and debris – to nearby bodies of water.
A University of Florida scientist will embark on a study this summer, using Manatee County as his lab. But his results will apply to much of Florida, including Tampa Bay and Biscayne Bay.
