U.S. Department of the Interior Chemical Effects of Highway Runoff on the Surficial Aquifer, Broward County, FloridaWater-Resources Investigations Report 86-4200 By Barbara Howie and Bradley G. Waller
In many areas of Broward County,
swales are commonly designed to accept stormwater runoff from highways.
Two sites adjacent to heavily traveled highways were studied to determine
if stormwater percolating through unsaturated sand underlying the swales
may affect the quality of water in the Biscayne aquifer. Concentrations
of selected chemicals common in highway runoff were measured in swale stormwater,
in the unsaturated - zone percolate, and in the surficial aquifer during
12 storms, May through November 1983. Analyses of the unsaturated lithologic
material at the two test sites and one control site were also made to indicate
the extent of vertical attenuation of selected chemical constituents.
