The main objectives of this thesis were to generate preliminary data on the potential impacts of major categories of dust suppressants on the quality of urban runoff and to evaluate changes in the chemical composition of soils to which suppressants were applied. Eleven individual plots were topically treated with petroleum-based products, ligninsulfonate, acrylic polymers, magnesium chloride, fiber mulch, and non-petroleum-based products and one plot did not receive treatment (control). Rainfall was simulated and the runoff emanating from each plot was collected and analyzed for several parameters. In addition, the top two inches of soil from each plot were sampled after the rainfall events to determine the remaining levels of different suppressant. Analysis of the results shows that petroleum-based products presented higher number of contaminants with concentrations greater than the control, followed by acrylic polymer and ligninsulfonate. Magnesium chloride presented the lowest number of contaminants with concentrations greater than the control.
