In late 2019, University of Florida researcher, Dr. John Sansalone, completed a comprehensive 12-year study involving 14 Florida MS4s. Even though the study did not differentiate whether submitted data was produced by air sweepers or mechanical (i.e. broom) sweepers, the combined results were still astounding and, at the same time, confirmed what I believed to be the case as early as 1975 and have been teaching for more than four decades: Street sweeping should be considered the first line of defense for removing pavement-based stormwater runoff pollution degrading our nation’s waterways. Come learn more about this game-changing study, my personal journey, and what defines an “enhanced” street sweeping program and the benefits it can provide.
