CLS Labs <br /> GENERAL NARRATIVE <br /> Comments <br /> Test methods may include minor modifications of published EPA methods (e g , <br /> reporting limits or parameter lists) Reporting limits are adjusted to reflect <br /> dilution of the sample when appropriate Solids and waste are analyzed with no <br /> correction made for moisture content. <br /> Percent recoveries for laboratory control samples and matrix spikes have been <br /> calculated using unrounded concentration values Therefore, percent recoveries <br /> reported may differ slightly from those obtained from the rounded concentration <br /> values which appear on the report <br />' The analyses performed by CLS Labs in this report comply with the requirements <br /> under the following certification/approval CALIFORNIA --Hazardous Waste, #1417, <br />' Waste Water, # 1417 , Drinking Water, #1417 <br /> Abbreviations and Definitions <br /> MB Method Blank - An aliquot of a blank matrix carried throughout the <br />' entire analytical process <br /> LCS Laboratory Control Sample - A blank to which known quantities of <br /> specific analytes are added prior to sample preparation and analysis <br /> to assess the accuracy of the method <br /> MS/MSD Matrix Spike/Matrix Spike Duplicate - Duplicate samples to which <br /> known quantities of specific analytes are added prior to sample <br /> preparation and analysis to assess the extent of matrix bias or <br /> interference on analyte recovery <br /> RPD Relative Percent Difference The measurement of precision between <br /> duplicate analyses <br />' BRI,, Below Reporting Limit <br />' NS Not Specified <br /> NA Not Applicable <br />' Flags- <br /> Organics - <br /> J Estimated value below the reporting limit and at or above the method <br />' detection limit. <br /> B Analyte found in the associated blank, as well as in the sample <br />' E Exceeds linear range. <br /> Inorganics= <br /> B Estimated value below the reporting limit and at or above the method <br /> detection limit <br /> (cn14959) <br /> 3249 Fitzgerald Road 3083 Gold Canal Drive <br /> Rancho Cordova, CA 95742 Rancho Cordova, CA 95670 <br /> (916)638 7301 (916)852-6600 <br />' Fax (916)638 4510 Fax (916) 852 7292 <br />
