Subject:

FALSE POSITIVE TRITIUM FROM ANALYSIS OF WELL WATER

Description:

Originator: JAMES J VOUGLITOIS Supv Contacted: J. Kandasamy Condition

Description:

As part of the ongoing investigation of the tritiated water that leaked from underground pipes, monitoring well MW-1I-1A was sampled on 05/27/09.

The Chemistry Department filtered and analyzed this water sample in accordance with CY-OC-130-530 "Tritium Analysis Liquid Samples". The results of the analysis showed 83,000 pCi/L tritium. This result was inconsistent with the facts that all prior samples from this well showed no detectable tritium, and that the well is located in an area not believed to be impacted by the pipe leaks. Suspecting a false positive result due to interferences caused by sediment or micro-organisms in the sample, the sample was distilled andre-analyzed in accordance with CY-OC-130-530. The result of the re-analysis was less than the lower limit of detection.

Immediate actions taken:

Discussed the anomaloius result with the Chemistry Supervisor and requested the distallation/re-analysis.

Recommended Actions:

Close to trend.

What activities, processes, or procedures were involved?

Analysis of well water samples in accordance with CY-OC-130-530 "Tritium Analysis Liquid Samples" Why did the condition happen?

Interferences caused by sediment or micro-organisms in the sample.

What are the consequences?

None - The distallation and re-analysis in accordance with the procedure eliminated the interferences.

Were any procedural requirements impacted?

No - The analysis and re-analysis were performed in accordance with the procedure ( CY-OC-130-530 "Tritium Analysis Liquid Samplesý').

Were there any adverse physical conditions?
