This report describes the methods used to collect stormwater runoff and evaluate a street sweeping program on U.S. ; Highway 151 in Madison, Wisconsin. The study was a cooperative effort among the Wisconsin Department of ; Transportation (WisDOT), U.S. Geological Survey, and Wisconsin Department of Natural Resources. In a swept highway ; section, samples were collected to determine street dirt yields before and after a cleaning from either a vacuum-assisted or a ; mechanical-broom sweeper machine. Sweeping frequencies of twice per day, once per week, and once every two weeks ; were used during the study. On an unswept highway section of the study, street dirt yields are presented as weekly ; collections, and before and after runoff events. Water quality concentrations and flows are also presented for the unswept ; highway section. Average concentrations of selected contaminants are compared to concentrations measured in other ; studies of highway runoff. ; Changes in street dirt yields before and after sweeping and runoff events will be used to calibrate and verify the ; WinSLAMM model. By modifying the accumulation, event wash off, and street cleaning productivity equations in the ; model with the data from this study, WisDOT will be able to evaluate street sweeping programs on urban highways with ; curbs. A sweeping program is proposed as a best management practice to attain some of the 40% reduction in TSS ; prescribed in Wisconsin stormwater regulations. This report includes estimated daily-accumulation rates of street-dirt yields ; and percent of street-dirt washed off during a runoff event. Seasonal estimates of street-dirt yield reductions due to street ; sweeping are also presented. ; Concentrations and flows measured in the unswept highway section were used to calculate contaminant loads for each ; event. Loads were calculated for particulate and dissolved solids, inorganic compounds and trace metals. Sediment loads ; measured with a water quality sampler are augmented with the weights of sediment ... |
