SUBJECT:
ANALYTICAL RESULTS FOR SIX WATER SAMPLES COLLECTED MAY 23, 2006 FROM TRONOX-CIMARRON CORPORATION, CRESCENT, OKLAHOMA (INSPECTION REPORT #070-00925/06-001) [RFTA NO. 06-001]
Dear Ms. Schlapper:
The Oak Ridge Institute for Science and Education (ORISE) received six water samples for analysis from Tronox-Cima.rron Corporation, Crescent, Oklahoma on May 25, 2006. The samples were analyzed for gross alpha, gross beta, and uranium alpha isotopic. The gross alpha and gross beta data are presented in Table 1. The uranium isotopic data are presented in Table
- 2. The pertinent procedure references are provided in the specific tables.
ORISE's Quality Control (QC) requirements were met for these analyses. The QC files a.re 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.
Sincerely, QJL -cL Dale Condra, tfanager Laboratory RDC/WPI:db Enclosures c:
