### SECTION D

- 1 . QC INFORMATION

– Instrument Calibration

1. Calibration Curve: Were a s eries of standards within the standard range and one blank used to create a calibration curve? (4500 CN E/4a)

What were the concentrations of the calibration standards used by lab?

2. Calibration Curve Verification (CCV) : Was the calibration curve checked periodically including every time the lab prepared a new reagent? (4500 CN E/4a) If provided, w hat were results reported for the

CCV?


### SECTION D

- 2 . QC INFORMATION

– Blan ks /Duplicates

1. Laboratory Blank: Was a blank (0.0 mg CN - /L) prepared and analyzed containing NaOH dilution solution and all solutions added to the samples?

Note a ny contamination reported by the laboratory.


### SECTION E . DETAILED RAW DATA REVIEW

– Sampl e Results

1. Calculation: Was the concentration in samples determined using the standard curve and were values reported in mg/L? (4500 CN E/5)

2. Dilution: Were only results between 5 and 20 ug/L reported and if a result was ≥ 20 ug/L, was the sample diluted and reanalyzed? (4500 CN A 3a)
