Case Narrative <br /> Client: Stockton Scavengers Association Inc TastAmeriGa Job ID: 28041009-2 <br /> Project/Site: CA10021Stockton Scavengers <br /> Job ID: 280-41009-2 <br /> Laboratory: TestAmerica Denver <br /> +s <br /> Narrative '` <br /> CASE NARRATIVE <br /> Client:Stockton Scavengers Association Inc <br /> Project:CA10021Stockton Scavengers <br /> Report Number:280-41009-2 <br /> Wth the exceptions noted as flags or footnotes,standard analytical protocols were followed in the analysis of the samples and no <br /> problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control <br /> limits,with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of <br /> the method. In some cases,due to interference or analytes present at high concentrations,samples were diluted. For diluted samples, <br /> the reporting limits are adjusted relative to the dilution required. <br /> This report may include reporting limits(RLs)less than TestAmerica's standard reporting limit. The reported sample results and <br /> associated reporting limits are being used specifically to meet the needs of this project. Note that data are not normally reported to these <br /> levels without qualification because they are inherently less reliable and potentially less defensible than required by the latest industry <br /> standards. <br /> Sample Receiving <br /> The sample was received on 04/12/2013;the sample arrived properly preserved and on ice.The temperature of the cooler at receipt was <br /> 4.7 C. <br /> Per the client's request,the samples OIL/WASTE SEPARATOR and METAL SHAVINGS were reported separately. <br /> Holding Times <br /> All analyses were performed within the established holding times. <br /> Method Blanks <br /> STLC Copper,STLC Beryllium Method 6010B and STLC Mercury Method 7470A were detected in the Method Blanks below the project <br /> established reporting limits.No corrective action is taken for any values in Method Blanks that are below the requested reporting limits. <br /> The Method Blank data are included at the end of this report. <br /> All other Method Blanks were within established control limits. <br /> Laboratory Control Samples(LCS) <br /> All Laboratory Control Samples were within established control limits. <br /> Matrix Spike(MS)and Matrix Spike Duplicate(MSD) <br /> All MS and MSD samples were within established control limits. <br /> Organics <br /> The sample METAL SHAVINGS was received with headspace in the sample vial for VOA analysis. <br /> General Comments <br /> For samples requiring analysis at a dilution,the dilution factor has been multiplied by the Method Detection Limit(MDL)for each analyte <br /> and evaluated versus the project-specific reporting limit(PSRL). If the obtained value is below the PSRL,then the PSRL is preserved as <br /> TestAmerica Denver <br /> Page 3 of 20 5/3/2013 <br />
