GENESIS ENGINEERING& REDEVELOPMENT <br /> The sample labels will be placed on the bottles so as not to obscure any QA/QC data. Field <br /> identification must be sufficient to allow easy cross-reference with the field logbook. <br /> 3.6.2 Sample Identification <br /> Each primary, duplicate, or split sample collected will be identified with an alphanumeric <br /> code. The first sequence of characters will be numbers, and will identify the project number <br /> as follows: <br /> 137 2303 West Lane <br /> The next sequence of characters in the sample code will identify the sampling location and <br /> media type of the sample: <br /> Sample Type Code Sample Type <br /> B-1 W Groundwater sample from direct push B-1 location <br /> B-IS Soil sample from boring B-1 <br /> DUP-1 Duplicate sample from designated location <br /> TB Trip Blank <br /> The final sequence will identify depth of the soil sample. <br /> -50 Depth of sample <br /> Example sample designations: <br /> 137-B-1W-50 represents a water sample collected from boring location B-1 at depth <br /> of 50 feet below grade. <br /> Quality control samples include a duplicate sample,trip blank, and matrix spike/matrix spike <br /> duplicate samples. The following is the labeling criteria for these samples. <br /> Duplicate Samples—Duplicate samples will be blind-labeled to conceal the actual <br /> sample location. DUP-1 represents a blind labeled duplicate groundwater sample. <br /> Duplicate samples will be documented as such on the field data forms. <br /> Trip Blanks—Trip blanks will be named with the project number followed by the <br /> characters "TB", followed by a number from that differentiates between multiple <br /> 2303 West Lane 6 of 1 1 <br /> Site Investigation Work Plan <br /> May 2009 <br />
