W. Washington, DC 20460 Re: Serum measurements for Argus Studies 418-013 (through lactation) and 418-015 (during gesatation) Dear Jennifer: I am including in this fax the two sets of serum perfluorooctanesulfonate measurements from the following two studies: 1. Oral (Gavage) Pharmacokinetic Recovery Study of PFOS in Rats, Argus Laboratories Protocol No. 418-015, 3M Reference No. T-6295.14, AdvancedBioanalyticalServices Study No. FACT-TOX-111. 2. Oral (Gavage) Pharmacokinetic Study of PFOS in Rats, Argus Laboratories Protocol No. 418-013, 3M Reference No. T-6295.12, Advanced Bioanalytical Services Study No. FACT-TOX-110. The informnation which I have included relates to the analytical studies indicated above in bold italics. Included are pages 10-19 of FACT-TOX-111 and pages 13-23 of FACT-TOX-110. 3M has previously sent the in-life reports and protocols for the analytical phase to the attention of Dr. Hernandez. I would be happy to meet with you and your EPA colleagues and consultants to provide whatever assistance you may desire in understanding the toxicological information that is being provided. Please contact me with any questions or if you would like to arrange a meeting. Sincerely, John L.
