CO Dear Sir/Madam: 3M has previously submitted data showing very low or non-detect levels of perfluorooctanesulfonate (PFOS) or other peril uorinated compounds in various municipal water samples. As a supplement to those submissions, 3M provides additional results as described below. PFOS has been detected at approximately 0.1 parts per billion (ppb) in a sample of surface water and a sample of municipal water used as intake water at a 3M production facility in Guin, Alabama. The plant previously used a PFOS-related surfactant material in product manufacture. The laboratory report showing the results of this sampling is enclosed, and also includes analyses of PFHS (detected at 0,03 ppb), PFOA (non-detect), and PFBS (non-detect). If you have any questions, please do not hesitate to contact Deanna Luebker at (651) 737-1374. Sincerely, Katherine E. Reed, PhD Staff Vice President Environmental Technology and Safety Services Enclosure vcc=jn C3 c~> i :v!U?.^roq3 --i n oo 89060000091 89 0 60000091 MET]
