Ambient Sampling Data
Box plots were created for all ambient data collected at S11.6SIC from 2004 - 2019. The parameters
collected at this site have varied over the years, therefore not every parameter was collected every year.
A large snowstorm occurred in January of 2017. As part of deicing efforts salt was applied to roads and
parking lots in the area. Multiple elevated parameters were observed following this event during routine
ambient monitoring, and are apparent in graphs below. For more details, please refer to Water Quality
Investigation 17WQ041.
