Key:
< or > - Amount detected is above or below equipment detection limit A - Approximate end time of flow due to power failure A-01 - >400000
B-02 - BOD result calculated from COD analysis D-1 - Elevated reporting limit(s) due to dilution. This has no effect on the data. Sample result is considered valid. DET - Analyte Detected
DRY – Sample results reported on a dry weight basis E - End time of flow due to equipment removal from site IS - Insufficient Sediment within Sample
J - Detected but below the reporting limit N/A - Data not available at this time ND - Analyte not detected at or above the reporting limit
NR - Not Reported NST – No Sample Taken U - Undetected
W-05 - Highest possible dilutions were made by the laboratory Qual – Qualifiers Q-5 - Seed correction outside desired limits. This has no effect on the data. Sample result is considered valid.
Q11 - Insufficient sample for analysis of matrix spike. This has no effect on the data. Sample result is considered valid. RPD - Relative Percent Difference S-1 - Laboratory container pH was above desired amount. This has no effect on the data. Sample result is considered valid.
TNTC - Too numerous to count U – Undetected W-05 - Highest possible dilutions were made by the laboratory
     
BOD - Biochemical Oxygen Demand BRL - Below Reading Limit COD - Chemical Oxygen Demand
TDS - Total Dissolved Solids TSS - Total Suspended Solids by EPA 160.2 PC - Sample results suspect due to post-calibration results
