Dear Mr. SneU:

The Oak Ridge Institute for Science and Education (ORISE) received Batch Four, consisting of three water samples on June 26,2006 that were collected in the vicinity of the Byon Generating Station in Byon, Illinois. The samples were analyzed for tritium using a liquid scintillation analyzer. The chain of custodyidentified one water sample to be analyzed by gamma spectroscopy (GS). The sample identifications and collection data are presented in Table 1. The GS data are presented in Table 2. The tricium data are presented in Table 3. The pertinent procedure references we provided in the specific tables.

ORISE's Quality Control (Qc) requirements were met for these analFes. The Qc files are avdable for your review upon request.

My contact dormation is listed below. You may also contact Wade Ivey zit 865.576.9184 with any questions or comments.
