SOURCES OF PCBS TO THE ATMOSPHERE IN CHICAGO
Citation:
SOURCES OF PCBS TO THE ATMOSPHERE IN CHICAGO. (2001).
Impact/Purpose:
The purpose of this study is to determine the flux of PCBs from sludge drying beds at the Calumet WRP of the Metropolitan Water Reclamation District of Greater Chicago and how this flux varies with time. The project will: (1) provide critical information about both local and remote sources of PCBs to the Great Lakes, (2) allow potential remediation strategies to be developed to control PCB emissions into the atmosphere, and (3) provide information that is needed to better estimate the amount of PCBs emitted from urban areas near the Great Lakes.
Description:
The project will obtain additional short-term PCB samples in southwestern Chicago to determine the amount of PCB emissions to the air from a sludge drying facility. Four different types of samples will be collected: (1) short-term ambient air samples surrounding the drying beds, (2) three-month integrated passive samples surrounding the drying beds, (3) flux chamber measurements, and (4) sludge samples.
