SUBJECT:
ANALYTICAL RESULTS FOR FOUR WATER SAMPLES, BATCH ONE, FROM THE VICINITY OF THE QUAD CITIES STATION, CORDOVA, ILLINOIS [INSPECTION REPORT NO. 050-00254/2006-0051 (RFTA NO.06-001)
Dear MI. Snek The Oak Ridge Institute for Science and Education (ORISE) received four water samples, Batch One, on l\\pril 26,2006 whch were collected in the vicinity of the Quad Cities Station in Cordova, Ihnois. The four water samples were analyzed for tritium 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.
ORISE's Quality Control (QC) requirements were met for these analyses. The QC files are avdable for your review upon request.
My contact information is listed below. You may also contact Wade hey at 865.576.9184 with any questions or comments.
