Description Stormwater and storm sediment discharge data were collected by NPDES Phase I Municipal Stormwater permittees between 2007 and 2013. The main goals of this study were to (1) compile and summarize the permittees’ data using appropriate statistical techniques and (2) provide a western Washington regional baseline characterization of stormwater quality. This analysis was based on the 44,800 data records representing 597 storm events, with 85 parameters analyzed in stormwater samples and 67 parameters in stormwater sediments. The results show differences in contaminant concentrations and mass loads among different land uses and between wet and dry seasons for many pollutants.
