ACZ Laboratories, Inc. August 10, 2007 <br />Quality Assurance Plan Version 12 <br />SOPAD018.08.07.12 Page 29 of 96 <br />7.2 Sample Receipt and Log-in <br />Upon delivery of samples to ACZ, Log-In personnel evaluate the condition of the cooler and custody seals. The <br />custody seals are then broken to retrieve the Chain of Custody (COC), which must be signed by the sample <br />custodian to document the transfer of possession of the samples to ACZ. Once a cooler is opened, the pH of <br />each sample is checked, if necessary, to verify the method preservation requirements have been met. The pH <br />check is documented along with cooler temperature, radioactivity screen and other pertinent sample information. <br />Any problems, such as expired hold times, lack of preservative or improper cooler temperature, are noted and the <br />Project Manager must contact the client as soon as possible so that a contingency plan can be initiated if <br />necessary. Samples are logged-in as outlined in the SOP Sample Receipt & Log-In Procedure / Maintenance of <br />Sample Integrity (SOPAD016) and are delivered to the assigned storage areas. Following log-in, every project is <br />reviewed by the assigned PM, and upon completion of the review, the client receives an electronic summary, <br />referred to as the "Login Review Report" that details the project information. This summary allows the client an <br />opportunity to make changes to the project before samples are analyzed. Refer to ACZ's SOP Client Service <br />Policies and Procedures (SOPAD043) for additional information. <br />7.3 Internal Custody Logs <br />Some clients may specify additional custody tracking of the samples once they have been logged in. Internal <br />custody may require that samples are stored in a manner that ensures limited access. The internal custody log <br />(FRMQA015) shall accompany the samples from log-in through completed analysis. The person responsible <br />for the work signs and dates each entry and/or page in the logbook. When all data from a sample set is <br />compiled, copies of all logbook entries shall be included in the final report package. For projects requiring <br />internal custody, ACZ will adhere to the procedure described in the SOP Client Service Policies and <br />Procedures (SOPAD043). <br />7.4 Sample Tracking <br />Sample flow through the laboratory is facilitated by the use of an Oracle-based LIMS database (Laboratory <br />Information Management System). Every product (requested analysis) logged into the LIMS for a sample has <br />a specific, pre-determined department path. All products have default paths of at least Login Review and <br />Reporting. Between these two departments, a product may go through, for example, Soil Prep and Metal <br />' Analysis or Soil Prep, Organic Prep and GC Analysis. At each department step in a product's path, the status <br />can be updated and viewed at any time. Analytical product statuses are defined below. Additional information <br />regarding sample tracking is available in the SOP Client Service Policies and Procedures (SOPAD043). <br />NEED Prep or Analysis has not been started <br />WIP Prep or Analysis has been started (Work In Progress) <br />PREP Sample preparation is complete and sample is ready for analysis <br />UPLD Analytical data has been uploaded into LIMS <br />AREV Analyst has reviewed and accepted analytical data <br />SREV Supervisor has reviewed and accepted analytical data <br />DONE Analysis or task has been completed <br />REDO Sample requires reanalysis <br />REDX Sample requires re-digestion/extraction <br />CANT Sample preparation or analysis cannot be performed <br />2773 Downhill Drive 970-879-6590 <br />Steamboat Springs, CO 90487 www.acz.com <br />
