GeosMtec'' <br /> consultants <br /> • Additional soil volume to ensure that the laboratory has sufficient sample volume <br /> to run the program-required analytical QA/QC samples for analyses (i.e., matrix <br /> spike/matrix spike duplicate samples); <br /> • A groundwater field duplicate to assess field precision; and <br /> • A trip blank will be used to verify that field collection and transport activities did <br /> not contaminate the sample. <br /> Table 4 lists the frequency of analysis for field QC samples. <br /> 3.3.2 Special Training Requirements/Certifications <br /> For sample preparation tasks, it is important that field crews be trained in standardized <br /> data collection requirements so that the data collected are consistent among the field crew. <br /> The lead field sampling staff will be trained in soil core collection and sampling methods, <br /> decontamination protocols, field documentation, and COC procedures. <br /> In addition,the 29 Code of Federal Regulations 1910.120 Occupational Safety and Health <br /> Administration (OSHA) regulations require training to provide employees with the <br /> knowledge and skills needed to perform their jobs safely and with minimum risk to <br /> personal health. All field crews will have completed the 40-hour Hazardous Waste <br /> Operations and Emergency Response training course and 8-hour refresher courses, as <br /> necessary, to meet OSHA regulations. <br /> 3.3.3 Laboratory Quality Control Procedures <br /> Laboratory QC procedures, where applicable, include initial and continuing instrument <br /> calibrations, laboratory control samples, laboratory replicates, matrix spike/matrix spike <br /> duplicate samples, surrogate spikes, and method blanks. Table 3 summarizes the <br /> laboratory performance criteria for laboratory precision, accuracy, and completeness. <br /> Table 4 lists the frequency of analysis for laboratory QC samples. <br /> Results of the QC samples from each sample group will be reviewed by the analyst <br /> immediately after a sample group has been analyzed. The QC sample results will then be <br /> evaluated to determine whether control limits have been exceeded. If control limits are <br /> exceeded, Geosyntec will be contacted immediately, and corrective action (i.e., method <br /> modifications followed by reprocessing the affected samples) will be initiated prior to <br /> processing a subsequent group of samples. <br /> 20190122- FINAL UST Data Gap Work Plan 12 22.01.2019 <br />
