The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. The recoveries for the compounds in the LCS Standard were high. New limits will be calculated. This sample will be reextracted and reanalyzed. This sample is the Field Blank. Reanalysis has a Surrogate Standard recovery of 89%.
