eurofins <br /> Air Toxics <br /> LABORATORY NARRATIVE <br /> EPA Method TO-15 <br /> Arcadis U.S.,Inc. <br /> Workorder# 1412110A <br /> One 1 Liter Summa Canister sample was received on December 08, 2014. The laboratory performed <br /> analysis via EPA Method TO-15 using GC/MS in the full scan mode. <br /> This workorder was independently validated prior to submittal using 'USEPA National Functional <br /> Guidelines' as generally applied to the analysis of volatile organic compounds in air. A rules-based, logic <br /> driven, independent validation engine was employed to assess completeness, evaluate pass/fail of relevant <br /> project quality control requirements and verification of all quantified amounts. <br /> Receiving Notes <br /> There were no receiving discrepancies. <br /> Analytical Notes <br /> There were no analytical discrepancies. <br /> Definition of Data Qualifying Flags <br /> Eight qualifiers may have been used on the data analysis sheets and indicates as follows: <br /> B - Compound present in laboratory blank greater than reporting limit(background subtraction not <br /> performed). <br /> J - Estimated value. <br /> E-Exceeds instrument calibration range. <br /> S - Saturated peak. <br /> Q -Exceeds quality control limits. <br /> U -Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See <br /> data page for project specific U-flag definition. <br /> UJ-Non-detected compound associated with low bias in the CCV <br /> N- The identification is based on presumptive evidence. <br /> File extensions may have been used on the data analysis sheets and indicates <br /> as follows: <br /> a-File was requantified <br /> b-File was quantified by a second column and detector <br /> rl-File was requantified for the purpose of reissue <br /> Page 3 of 9 <br />
