The samples were received and logged in following normal lab procedures. All samples were received under Chain of Custody and in good condition unless otherwise noted. NIOSH 7300 Modified LA Testing Order: 332321769, Project ID: PROJ-032229: All samples were prepared and analyzed according to the method specified NIOSH 7300 Modified. The samples were submitted on cellulose ester membrane filters which were prepared utilizing a hot block digestion technique as indicated in the method. The samples were then analyzed via Inductively Coupled Plasma (ICP) analysis utilizing Atomic Emission Spectroscopy (AES). All preparation and analyses were performed within the method specific hold time requirement. Results are reported in mg/m3. Quality Control Dilutions: None Calibrations: The RL, RLVS ICV and bracketing CCV standards were within control limits. Blanks: Target analytes were not detected above the reporting limit in the associated blanks. Media blank was not subtracted from sample concentrations. LCS/LCSD: The laboratory control sample spike recoveries and RPD results were within control limits. ICSA/ICSB: The interference check solution results were within control limits. QC was performed at rates compliant with both the American Industrial Hygiene Association (AIHA) and the California Environmental Laboratory Accreditation Program (ELAP). 1 certify that this report is in compliance with the terms and conditions of the contract, both technically and for completeness, for other than the conditions detailed above. In addition, I certify, that to the best of my knowledge and belief, the data as reported are true and accurate.
