The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. The recovery for the Surrogate Standard in this sample was below its acceptance range. This sample will be re-extracted and re-analyzed. Re-analysis was performed with a Surrogate Standard recovery of 95%. Also, the pH of this sample when received was less than 2.
