Two locations, Lake Ivanhoe and the Maitland interchange of Interstate 4, were selected to study the impact of bridge runoff on receiving water bodies. The Lake Ivanhoe location includes two similar bridges, one without scuppers and one with scuppers. The Maitland interchange site has several borr ponds which drain to Lake Lucien. Samples were collected from Lake Ivanhoe below the bridges and in the open lake away from the bridges. Also samples were collected from the east pond, west pond, and lake Lucien, at the Maitland interchange. Samples included water, sediments, plants and benthos to detect differences, if any, in heavy metal concentration due to sampling location. Heavy metals tested included: ZN, Cu, Cr, Cd, Pb, As, Fe, and Ni. Dissolved oxygen, temperature profiles and secchi desk transparency were measured in the field. Additional water quality parameters such as pH, turbidity, carbon and phosphorus were evaluated. Results indicated significant differences in specific heavy metal concentrations exist between samples collected beneath a bridge with scuppers compared to samples collected beneath a bridge without scuppers. Also, the drainage ponds appear to contain more heavy metals than the adjacent Lake Lucien at the Maitland interchange.
