Dietrich - Res. 2 This memo confirms the analysis results given to you on 4/15/70, also included are the analytical results for the Timken Bearing effluent samples. The samples numbered 203 and 204 contained a large unidentified electron capture (E.C.) peak in addition to the normal peaks seen for Aroclor 1242. The E.C. chromatograms of samples 208, 209, 220, 221, and 222 were altered with respect to Aroclor 1242 in that one or two peaks were missing. In all other respects the chromatograms were equivalent to that of Aroclor 1242. att. db E. S.
