Case Narrative <br />Analytica Environmental Laboratories, Inc. <br />Work Order: B1110173 <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 />Pfaff, J. D., C. A. Brockhoff and J. W. O'Dell. 1994. The Determination of Inorganic <br />Anions in Water by Ion Chromatography. Method 300.0A. U. S. Environmental Protection <br />Agency. Environmental Monitoring Systems Lab. <br />SAMPLE RECEIPT: <br />Two (2) samples were received on 10/24/2011 at 8:35:00 AM at a temperature of 20 °C at <br />Analytica- Thornton. The samples were received in good condition and in order per chain of <br />custody. <br />Comments: One procedure was received out of the method specified holding time. The <br />client gave the lab permission to proceed with the filtration. <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 - Ground Water <br />Test Method: Filtration for Dissolved Metals - Ground Water <br />HOLDING TIMES: <br />Filtration for dissolved targets should be performed in the field, within 15 minutes of <br />sampling. Per client request, filtration was performed as soon as possible upon sample <br />receipt. <br />HOLD TIMES MISSED OR DATE ERRORS: <br />Sample CRMW- 35A,B1110173 -01A <br />Sampled: 10/21/2011 10:47:00 AM, Prepped: 10/27/2011 5:10:00 PM <br />Sampled: 10/21/2011 10:47:00 AM, Analyzed: 10/27/2011 5:10:00 PM <br />Regulatory hold time: 15 Min <br />Sample CRMW- 63B,B1110173 -02A <br />Sampled: 10/21/2011 11:15:00 AM, Prepped: 10/27/2011 5:10:00 PM <br />Sampled: 10/21/2011 11:15:00 AM, Analyzed: 10/27/2011 5:10:00 PM <br />Regulatory hold time: 15 Min <br />Test Method: Inorganic Anions by Ion Chromatography - Anions by IC2 - Ground Water <br />
