All results have been found to meet all requirements of NELAC and any exceptions are noted below. This report shall not be reproduced except in full, without the written approval of the laboratory or sponsor. Dilution factors and footnotes have been provided on each datasheet to assist in the interpretation o f the results. Sample Arrival and Receipt The three water samples presented in this report was received at the TestAmerica Denver laboratory at a temperature of 3.1C on July 19,2007. Standards. Analytical standards were prepared using the acid form o f the compound perfluorooctanoic acid (PFOA). FFOS is a commercial prepared and certified solution. Perfluoro-n-[l^,3,4-,5C4]octanoic acid was introduced at the extraction step and was used as an internal standard for quantitation o f PFOA. Perfluoro^l -[1,2,3,4-13C4]octanatesulfonate was introduced at the extraction step and was used as an internal standard for quantitation o f PFOS. Sample Extraction and Analysts The samples presented in this report were analyzed for the target analytes by TestAmerica Denver's SOP DEN-LC-0012. For water samples a 250 raL aliquot o f each sample is acidified with 1 mL o f 6N HC1 solution and it is extracted using solid phase extraction technique with methanol conditioned C l 8 cartridges. Each sample is spiked with the internal standard, prior to extraction. After the sample is passed through the cartridge, the analytes are eluted with 4 mL o f methanol. The final volume is brought to 5 mL rising methanol and the extract is analyzed by LC/MS/MS. Method OC Samples The Method Blank is processed reagent water spiked with surrogate and prepared with each batch of 20 samples o f the same matrix. The method blank was non-detect at the reporting limit for the target analytes. Each batch is prepared with Laboratory Control Samples (LCS). The LCS recoveries for both levels were within established control limits. Analytical Comments The method required MS/MSD could not be performed for QC batch 7201367 due to insufficient sample volume. All other QC was in control. No other anomalies were noted. EXECUTIVE SUMMARY - Detection Highlights D7G190493 PARAMETER RESULT BIRCH CREEK POE 07/17/07 10:10 002 .PFOS PFOA 0.0079 J 0.069 DRRWTP POE 07/17/07 12:40 003 pros PFOA 0.0085 J 0.011 J REPORTING ANALYTICAL LIMIT UNITS_____ METHOD 0.010 0.015 ug/L ug/L DEN -LC-0012 DEN -LC-0012 0.010 0.015 ug/L ug/L DEN -LC-0012 DEN -LC-0012 NJAW0006 METHODS SUMMARY D7G190493 PARAMETER __________________________ .
