LFR Levine-Fricke <br /> Quality Assurance/Quality Control (QA/QC) samples will be collected in accordance <br /> with Appendix A of this Work Plan. Appendix A provides a summary of the data <br /> validation and quality control measures to ensure that the environmental data obtained <br /> are defensible and of high enough quality to meet the objectives. Laboratory QA/QC <br /> will include analysis of matrix spikes recovery, matrix spike duplicate analysis, and <br /> method blanks. Field QA/QC sampling will consist of collection and laboratory <br /> analysis of one field duplicate sample per sampling event. Equipment blanks will not <br /> be taken because each well has a dedicated bailer. Data will also be submitted in a <br /> digital format acceptable to the RWQCB on an annual basis. <br /> Table 2 provides a summary of the sampling parameters, sample container <br /> requirements, filtering, maximum hold times allowed, and preservation of samples. <br /> I <br /> Table 2.
