Creek Soil & Sediment Removal Action
- Initial screening of floodplain soil, surface water,
sediment, and fish/crayfish was completed in October
- Results of the October 2001 investigation indicated
a general occurrence of PCBs in surface water,
stream sediments, fish/crayfish, and flood plain
soils along Bailey’s Branch and Pleasant
Run to the east of the Plant.
- PCB levels generally decrease with distance
from the plant and the stream.
- 2.0 parts per million (ppm) for total PCBs was used
as a screening level for floodplain soils.
- 2001 Stream Investigation Data Summary was distributed
to U.S. EPA, IDEM, and USFWS on March 19, 2002.
- Additional floodplain soil sampling was initiated
by GM in January 2002 based upon the results of the
October 2001 sampling activities.
- Over 3,000 samples collected to date.
- Sample collection, sample analysis, data validation/
completion, and distribution to property owners
- Results of 2002 stream investigation provide
an understanding of the extent of the occurrence
of PCBs in flood plain soils.
- Additional sampling has included:
- Agricultural fields soil, corn, soil in vegetable
gardens, cattle, and water from springs and seeps.
- High flow water sampling was conducted in May 2002.
- Summary Report of 2002 sampling was submitted
to U.S. EPA and IDEM on February 11, 2003 and is
available in the public repositories and on-line.
