Dear Mr. Snell:
The Oak Ridge Institute for Science and Education (ORISE) received four water samples, Batch One, on April 25,2006 which were collected in the vicinity of LaSalle Station in LaSalle, I h o i s. 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. 'lhe GS data are presented in Table 2. The tritium data are presented in Table 3. The pertincnt procedure references are provided in the specific tables.
ORISE's Quality Control (QC) requirements were met for these analyses. The QC files are available for your review upon request.
