Flag Definition
4C Parameter is composite result of four grab samples.
4F Parameter result of four grab samples analyzed in field.
B Analyte was present in an associated method blank
BB Dilution water blank exceeds 0.20 mg/L.
BD Depletion <2 mg/L.
BG Glucose-glutamic acid check falls outside limits.
BT Test replicates show more than 30% difference between high and low values. Sample toxicity is possible. Best result was reported.
C Result provided by client.
D1 Duplicate was not within control limits. The sample concentration was less than ten times the reporting limit.
D2 Duplicate was not within control limits due to non-homogeneous nature of sample.
D3 Duplicate was not within control limits.
DC Peaks in diesel range but chromatogram does not match that of diesel standard.
F Field result.
GA Parameter analyzed using grab sample at end of sampling period.
I1 Possible interference. Reported value may be suspect.
L The laboratory control sample (LCS) was out of control limits. The sample data was reported without further clarification.
L1 LCS was not within control limits. The MS or MSD met LCS limits which validated the batch.
MDO Minimum DO is less than 1.0 mg/L. Result may be higher.
MS Matrix spike was not within control limits due to possible matrix interference.
MS1 Matrix spike was not within control limits due to possible matrix interference. LCS was acceptable.
MS2 The analyte concentration in the sample exceeded the spike level by a factor of four or greater, spike recovery and limits do not apply
NE Non-accredited result. Cannot be used for regulatory purposes.
