Seven solid media samples were received by Centre Analytical Laboratories, Inc. (dba Exygen Research) (Exygen) from DuPont Corporation. The media represent samples of air collected on OVS tubes. Please see Table 1 for a completed listing of samples received and field air volumes collected. Sample WWK-A-AMS3-E7 had.sampler problems during collection. No results are reported for this sample. The samples Were analyzed for Perfluorooctanoic Acid (C8 Acid) using liquid chromatography /mass spectrometry (LCMS). The method employed is entitled "Method of Analysis for the Determination of Perfluorooctanoic Acid (PFOA) in OVS Airtubes by LCMS" (James Miller Exygen Research, February 17, 2003). The OVS tubes were separated into three fractions for specific fluorochemical analysis. Fraction A consisted of the filter, backing material and plastic ring. Fraction B contained the first bed of XAD resin and the PUF backing. Fraction C contained the second bed of XAD resin and PUF backing. Fractions A and B were extracted with 1 mL of methanol. Fraction C was not analyzed but saved for possible future analysis. Perfluorodecanoic Acid (C10 Acid) was added as a surrogate spike to each fraction prior to extraction. Instrument operating conditions can be found at the beginning of each analytical run. Raw instrument data is given in Appendix A. Chain-of-custody information can be found in AppendixB; ALL DATA CONTAINED IN THIS REPORT WAS GENERATED BY EXYGEN RESEARCH Page 2 of 7 Rpsults Summary Request # WWK-A-AMS1-E7 A WWK-A-AMS1-E7 B WWK-A-AMS1-E7 C WWK-A-AMS1-E7 (Total) Air Volume Sampled (L) 1356^ ' . , 1356 1356 C8 Acid (mg/m3) 0.0003 < 0.00007 NA 0.0003 ' WWK-A-AMS2-E7 A : : WWK-A-AMS2-E7 B WWK-A-AMS2-E7 C WWK-A-AMS2-E7 (Total) 1490 1490 1490 0.0003 < 0.00007 NA 0.0003 WWK-A-AMS4-E7 A WWK-A-AMS4-E7 B WWK-A-EMS4-E7 C WWK-A-EMS4-E7 (Total) 1652 1652 1652 < 0.00006 < 0.00006 NA < 0.00012 WWK-A-AMS5-E7 A WWK-A-AMS5-E7B WWK-A-AMS5-E7 C WWK-A-AMS5-E7 (Total) .: .1530 1530 1530 < 0.00007 < 0.00007 NA < 0.00014 , .WWK-A-AMS6-E7A WWK-A-AMS6-E7 B WWK-A-AMS6-E7 C WWK-A AMS6-E7 (Total) 1539 1539 1539 < 0.00006 < 0.00006 NA < 0.00012 NA - Not Analyzed.
