Because of safety concerns, the sampling crew could not correct the malfunction in the field. Stream stage was observed by the sampling crew at 1.5 inches above the bubbler during the sampling routine.

The rise depicted on the graph at this time was due to debris moving the bubbler. The bubbler was a refastened and recorded properly for the remainder of the storm event. The flow end time and date area a result of the sampling equipment being removed.

Because of safety concerns, the sampling crew could not access the bubbler in the stream due to fast flowing waters, making it unsafe. Stream stage was recorded by the sampler to have risen at 0.7 ft during the sampling routine. An additional aliquot is shown on the graph due to initializing the automatic sampler twice but was not collected.

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
