ANALYTICAL RESULTS FOR FIVE WATER SAMPLES, BATCH FOUR, FROM THE VICINITY OF LaSALLE STATION, LaSALLE, ILLINOIS

[INSPECTION REPORT NO. 050-00373/2006-0051 (RFTA NO.06-001)

Dear Mr. Cameron:

The Oak Ridge Institute for Science and Education (ORISE) received Batch Four, consisting of five water samples, July 25,2006 which were collected in the vicinity of 1,aSalle Station in LaSalle, Illinois. The five water samples were analyzed for tritium to a minimum detectable concentration of 190 pCi/L using a liquid scintillation analyzer. The chain-of-custody identified 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 tritium data are presented in Table 3. The pertinent procedure references are provided in the specific tables.

OKISE's Quality Control (QC) requirements were met for these analyscs. The QC files are available for your review upon request.

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