Quality Assurance

The ESER Quality Assurance Program consists of five ongoing tasks which measure:

1. method uncertainty
2. data completeness
3. data accuracy, using spike, performance evaluation and laboratory control samples
4. data precision, using split samples, duplicate samples and recounts
5. presence of contamination in samples, using blanks.

Data completeness for sample collection and delivery was 100 percent during the fourth quarter, with the following exceptions.

There were four air samples that had volumes below the 7,000 ft³ or 200 m³ threshold listed in the air sampling procedure as being a valid sample.  All were from the FAA Tower due to a power outage.  The power had to be reset from inside the building by personnel of the FAA and then reset outside the building by ESER personnel.

Two milk samples were not collected in the fourth quarter.  The cow at Fort Hall was dry during one month and the goat dairy in Blackfoot was not operating in November.

Sample results are compared to criteria described in the Quality Assurance Project Plan for the INL Site Offsite Environmental Surveillance Program (Stoller 2007). The following table summarizes the results of the quality assurance program for the fourth quarter of 2010.
