The GCMS scan, from 35 to 550 amu does not reveal the presence of any unusual compounds. The recovery for 1 of the 43 compounds in the LCS Standard was above its acceptance range. The recovery for the Surrogate Standard in this sample was below 70%. This sample will be re-extracted and re-analyzed. This sample was re-extracted with a Surrogate Standard recovery of 61%, compared to 59% the first time.
