# validation_reason

validation_reason:
qualified due to low abundance ( radiochemical activity)


validation_reason:
qualified due to equipment blank contamination


validation_reason:
qualified due to field blank contamination


validation_reason:
qualified due to lab blank contamination


validation_reason:
qualified due to trip blank contamination


validation_reason:
qualified due to pump blank contamination (wells w/o dedicated pumps, when contamination is detected in the Pump Blk)


validation_reason:
qualified due to filter blank contamination (aqueous Hexavalent Chromium and Dissolved sample fractions)


validation_reason:
qualified due to insufficient ingrowth (radiochemical only)


validation_reason:
concentration exceeded the calibration range


validation_reason:
qualified due to field duplicate imprecision


validation_reason:
qualified due to holding time exceedance


validation_reason:
qualified due to internal standard areas


validation_reason:
qualified as Estimated Maximum Possible Concentrations (dioxins and PCB congeners)


validation_reason:
qualified due to lab duplicate imprecision (matrix duplicate, MSD, LCSD)


validation_reason:
qualified due to matrix spike recoveries


validation_reason:
qualified due to negative lab blank contamination (nondetect results only)


validation_reason:
qualified as a false positive due to contamination during shipping


validation_reason:
serial dilution did not meet control criteria


validation_reason:
qualified due to elevated helium tracer concentrations


validation_reason:
volatile headspace detected in aqueous sample containers submitted for VOC analysis


validation_reason:
sample preservation not within acceptance range
