Description:
A monitoring program was conducted to determine PCB levels in ambient air on and in the vicinity of two landfills at which interim remedial cleanup measures have been performed. The landfill sites are in the Bloomington, Indiana area. The sampling locations and methods used were the same as employed in a pre-cleanup monitoring program conducted during June and July, 1983. Monitoring data obtained at former hot spots (on the sites where exposed capacitors were visible) showed a marked reduction from the pre-cleanup monitoring levels. However, PCB concentrations measured at downwind locations at the site boundaries during the pre- and post-cleanup monitoring were approximately the same. Collected monitoring conducted during the study showed that both the low- and high-volume sampling methods yielded reliable, reproducible measurements of airborne PCB levels.
