If present, there will <br />be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report. <br />This section of the report includes the results of the laboratory quality control analyses required by procedure or <br />analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not <br />being performed on your samples typically, but on laboratory generated material. <br />This is the document created in the field when your samples were initially collected. This is used to verify the time and <br />date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This <br />chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the <br />samples from the time of collection until delivery to the laboratory for analysis. <br />This section of your report will provide the results of all testing performed on your samples. These results are provided <br />by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for <br />each sample will provide the name and method number for the analysis reported. <br />This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and <br />times of preparation and/or analysis. <br />Description <br />The remainder of this page intentionally left blank, there are no qualifiers applied to this SDG. <br />ACCOUNT: <br />UPRR - American Integrated Services, Inc <br />PROJECT: <br />AIS-9020-117 <br />SDG: DATE/TIME: PAGE: <br />L1286525 12/01/20 09:45 5 of 11
