SUBJECT:
ANALYTICAL RESULTS FOR 37 WATER SAMPLES FROM THE VICINITY OF T H E DRESDEN GENERATING STATION, DRESDEN, ILLINOIS
[INSPECTION REPORT NO. 05-000237/2006-0031 (RFTA NO.06-001)
Dear MI. Snell:
'l'he Oak Ridge Institute for Science and Education (ORISE) received 37 water samples on March 20 that were collected in the vicinity of the Dresden Generating Station in Dresden, Illinois. 'lhc 37 warcr samples were analyzed for tritium using a liquid scintillation analyzer (Procedures M'2, Rcvlsion 15 and C1'4, Revision 3). The chain of custody identified the individual water samples to be analyzed by gamma spectroscopy (GS) (Procedure CPl, Revision 15). The sample identifications and collection data are presented in Table 1. The GS data are presented in Table 2. The tritium data arc presented in Table 3.
ORISE's Quality Control (QC) requirements were met for thesc analyscs. The QC fdcs 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 commcnts.
Sincerely.
