SUBJECT:

ANALYTICAL RESULTS FOR SEVEN WATER SAMPLES, BATCH TWO, FROM THE VICINITY OF THE DRESDEN GENERATING STATION, DRESDEN, ILLINOIS [INSPECTION REPORT NO. 050-00237/2006-0071 (RFTA NO.06-001) llcar MI. SneU The Oak Ridge Institute for Science and Education (ORISE) received seven water samples on April 25, 2006 that were collected in the vicinity of the Dresden Generating Station in Dresden, Illinois. The seven water samples were analyzed for tritium using a liquid scintillation analyzer. The chain-of-custody identified the two water samples to be analyzed by gamma spectroscopy (GS). The sample idcntifications 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 thc specific tables.

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