Map of Indian River Inlet sampling sites. In 2008, sites sampled were 1, 2–1, 2–2, 3, 4, 5, 7, 12. In 2009, sampling was expanded to all locations (1 through12). Symbols (▲ ■ X) refer to 2009 data only. In 2009, sediment sampling was expanded to include all 13 locations, and triplicate samples were taken at each site. Sites from which none of the triplicate samples were positive are indicated by crosses (X), sites with one of the triplicate samples positive are indicated with triangles (▲), and sites from which all three triplicates were positive are indicated with squares (■).
