Five samples of water have been analyzed for perfluorooctanoate (CB)
by electron capture gas chromatography. Method ES-567 was used with the
following modifications: sample size was 10 g; lyophilization was -18-20 concentration of perfluorodecanoate internal standard was decreased

standards <.4 ppb.
For the quantitation we had linear calibration curves over
the range of 0.4 to 1.9 ppb. The samples were freeze dried, derivitized, and
analyzed in duplicate. The results are expressed as ppb fluoride where
ppb F = 0.688 x ppb perfluorooctanoate.
The results are given in the attached table. questions, don't hesitate to call.
