From the Purpose and Scope: "The purposes of this report are to describe the methods and data collected from urban flowpath sites in Rapid City during 2016-18 and to provide statistical summaries of the water-quality data for the various infrastructure site types that were sampled for the stormwater-quality study. This information could be used in hydrologic models to estimate FIB [fecal indicator bacteria] and TSS [total suspended solids] loading from certain infrastructure elements in urban environments. This study only involved data collection within the city of Rapid City; however, the results are transferable to urban drainages in cities with similar infrastructure and climate."
