The recovery for the Surrogate Standard in this sample was 71%. Recoveries for 16 of the 44 compounds in the LCS Standard were outside of their acceptance ranges. This sample was re-extracted on 12/3/01 and re-analyzed. Results were similar. The Surrogate Standard recovery was 89% and 1 of the 43 compounds in the LCS Standard was above its acceptance range.
