Title

Impact Of Bridging On Floodplains.

Abstract

Three bridge sites in central Florida were selected to study the feasibility of treating highway runoff by using floodplains beneath these bridges, and the impact of bridging on biological diversity and productivity. Soil and plant samples were collected from bridge areas affected by highway runoff as well as control areas upstream and downstream of the bridge areas. These samples were analyzed for extractable heavy metals to study the capacity of floodplain areas to retain these metals. Soil samples collected from the bridge areas contained significantly higher concentrations of metals, particularly lead, than the control areas. Metals were fixed in the soil and could be released to the surrounding body of water by highly acidic environments, organic chelating agents, and erosion processes. Plants were also surveyed to determine dominant species, changes in diversity, and productivity at the bridge and control areas.
