Data include Rhodamine WT dye concentrations measured every 3 or 10 minutes by means of Turner Designs C-3 and C-6 fluorometers with internal dataloggers at three fixed locations on the Des Plaines River (DPR) (DP-1, DP-2, and DP-3); in three groundwater monitoring wells (ACL-1, WP10-85, and WP9-275); and at two fixed locations on the Chicago Sanitary and Ship Canal (CSSC) (SC-1 and SC-2) (see included Google Earth file AllDeployments_Locations.kmz). The detection limit for these fluorometers is reported to be 0.01 parts per billion (ppb). However, the fluorometer readings were affected by turbidity, and readings of less than about 1.0 part per billion (ppb) were considered to have been influenced by turbidity and...

A boat equipped with a differential Global Positioning System (GPS) receiver (Hemisphere Crescent A100 Smart Antenna) and a Turner Designs C3 submersible fluorometer was used to survey the spatial distribution of the Rhodamine WT dye in the Chicago Sanitary and Ship Canal (CSSC) throughout the study area. The fluorometer was installed in a fixed, downlooking orientation approximately 1 foot below the water surface. Fluorometer readings were taken at a frequency of 1 per second. Data were acquired on a personal computer running the Turner Designs C-FINS software extension for ArcGIS 10. This data acquisition software allows the C3 data to be georeferenced and plotted in real time as color-coded concentrations on...
