Qualifiers and Comments

SDG: 121738 Reported: 07/16/12 15 :4 5

Q6 Matrix spike/matrix spike duplicate precision criteria were not met for this analyte (see MS/MSD results for this batch in QC summary).

Q4 The matrix spike and/or matrix spike duplicate associated with this sample did not meet recovery criteria for this analyte (see MS/MSD results for this batch in QC summary)

Q I 0 The analyte concentration in the unfortified sample is significantly greater than the concentration spiked into the matrix spike and matrix spike duplicate. The reported spike recovery is not a meaningful measure of the dataset's analytical accuracy.

1 The reported result for this analyte should be considered an estimated value.

C I The reported concentration for this analyte is below the quantitation limit.

U Not Detected

NR Not Reported

REI, RE2, etc: Result is trom a sample re-analysis.
