This narrative covers the analysis of two (2) <br /> water samples in accordance with SW--646 <br /> 2 . Initiation of sample analysis was within holding time for <br /> the FCD analysis . However, analysis made on the PID was <br /> made outside of holding time <br /> 3 . Initial and continuing calibration criteria were met for <br /> this analysis. <br /> 4 . The method blank associated with this group of samples <br /> was not free of target analyte interferences at, or above, <br /> the reporting limits. However, the samples were clean and <br /> did not show any carryover peaks . <br /> S . Surrogate recoveries were within laboratory limits, <br /> 6. spike recoveries were within acceptable limits . <br /> -411qq-4 J__ <br /> G.R. Adamd Date <br /> Unit Leader <br /> • <br />
