Dry weight calculations based upon % solids obtained as outlined in EPA method 5035 section 7.5 MS and MSD were not performed for PAH QC batch PAH 00414_L due to limited sample quantity. VOC percent differences of Dichlorodifluoromethane, Chloromethane, Vinyl Chloride, Bromomethane, Carbon Tetrachloride and 1,2- Dichloroethane were outside Oxidor QC limits for QC batch VOC 31809_L. Percent recoveries were still within Oxidor QC limits. This report is intended only for the use of W &M Environmental Group, Inc. and may contain information that is privileged and confidential.
