Summary
Note: This data release is currently being revised and is temporarily unavailable. Two types of passive samplers for polychlorinated biphenyl (PCB) analysis were deployed in the Clinton River Area of Concern in 2019: semipermeable membrane devices for water and in-stream sediment samplers. Samplers were deployed in July 2019 and retrieved in August 2019. Additionally, bank sediment samples for PCB analysis were collected by the U.S. Geological Survey (USGS) in August 2019 and catch basin bottom material samples for PCB analysis were collected by LimnoTech in November 2019 under contract with the U.S. Army Corps of Engineers. These data are a part of a larger study and associated USGS report (https://doi.org/TBD).

The purposes of this study were to 1) use passive samplers to sample upstream and downstream of PCB hotspots to assess if the outfalls or other inputs were potential sources of PCBs to the river; 2) collect samples of sediment to evaluate the potential for these sediments to contribute PCBs to the river, and 3) provide data to help determine the extent of sediment PCB concentrations greater than 1 ppm in the areas with the highest PCB concentration. Ultimately, the study goal was to determine if there were current sources of PCBs that were high enough to cause the observed high PCB concentrations in bottom sediment of the dredged navigation channel in the study reach.
