The GCMS scan, from 35 to 550 amu, does not reveal the presence of unusual compounds. The recoveries for 9 of the 43 compounds in the LCS Standard were below their acceptance ranges. Because of the low Surrogate Standard recovery this sample will be reextracted and reanalyzed. The reextracted sample had a Surrogate Standard recovery of 169%.
