Occupational Serum sampling
DuPont Performance Elastomers
Chambers Works Facility, Deepwater, New Jersey

Please find attached occupational PFOA serum sampling results for workers at the above
referenced DuPont site for samples collected in October 2009. The levels of PFOA reported with
this submission are generally corroborative of previously reported levels in an occupational
setting. This information is provided to the TSCA 8(e) office in view of the Agency's continued
interest in perfluorinated substances and as a precautionary measure.
Sincerely,
