Case Narrative <br />Analytica Environmental Laboratories, Inc. <br />Work Order: B1005139 <br />Samples were prepared and analyzed according to EPA or equivalent methods outlined in the <br />following references: <br />Methods for the Determination of Metals in Environmental Samples, EPA/600/R-94/111, May <br />1994. <br />Standard Methods for the Examination of Water and Wastewater, 20th Edition, 1998. <br />Pfaff, J. D., C. A. Brockhoff and J. W. O'Dell. 1994. The Determination of Inorganic <br />Anions in Water by Ion Chromatography. Method 300.OA. U. S. Environmental Protection <br />Agency. Environmental Monitoring Systems Lab. <br />SAMPLE RECEIPT: <br />Sixteen (16) samples were received on 5/20/2010 at 1:55:00 PM at a temperature of 4.0°C <br />at Analytica-Thornton. The samples were received in good condition and in order per chain <br />of custody. <br />REVIEW FOR COMPLIANCE WITH ANALYTICA QA PLAN <br />A summary of our review is shown below. <br />All analytical results contained in this report have been reviewed under Analytica's <br />internal quality assurance and quality control program. Any deviations in quality control <br />parameters for specific analyses are noted in the following text. A complete quality <br />assurance report, including laboratory control, matrix spike, and sample duplicate <br />recoveries, is kept on file in our office and is available upon request. <br />All method specifications were met for the following tests, unless otherwise noted: <br />Test Method: 200.7 - Metals by ICP - Dissolved Metals - Aqueous <br />Test Method: 200.7 - Metals by ICP - Total - Aqueous <br />Test Method: 200.8 - Metals by ICP/MS - Dissolved - Aqueous <br />METHOD BLANK OUTLIERS: <br />Manganese was detected above the PQL in the method blank, as shown below. Any detections <br />of this target in associated samples are flagged with a B to indicate that they are due to <br />laboratory background, unless the sample result is 5X or more the method blank level. <br />MB Batch Analyte Result PQL MDL <br />T100527011 Manganese 5.45 0.5 0.17 <br />Test Method: 200.8 - Metals by ICP/MS - Total Recov. Uranium - Aqueous <br />Test Method: 200.8 - Metals by ICP/MS - Total/TR - Aqueous <br />METHOD BLANK OUTLIERS: <br />Manganese was detected above the PQL in the method blank, as shown below. Any detections <br />of this target in associated samples are flagged with a B to indicate that they are due to <br />laboratory background, unless the sample result is 5X or more the method blank level <br />MB Batch Analyte Result PQL MDL <br />T100527011 Manganese 5.45 0.5 0.17
