10.0 Quality Assurance and Quality Control <br /> 10.1 Representativeness (Field Blanks) <br /> Field blanks and sample storage protocols all help assure the representativeness of the data. <br /> Field blanks provide assurances that the samples have not been contaminated during the <br /> sampling process, through shipping, handling, or transportation. Proper sample storage provides <br /> assurance that the samples do not become contaminated or degraded prior to analysis. <br /> During the sampling event, QC samples for each site location will be collected. One field blank <br /> per site (to determine if any asbestos contamination has occurred during the sample handling <br /> activities) and one sealed blank for the lot (to determine if any asbestos contamination has <br /> occurred during sample storage and shipping) will be collected per site. <br /> The results from analysis of these blanks will be included in the final report. <br />
