SUBJECT:
REPORT FOR ANALYSIS OF THE WATER SAMPLES FROM KERR-MCGEE CIMARRON, CRESCENT, OKLAHOMA (DOCKET NO.70-925; RFTA NO.01-015)
Dear Ms. Walker:
The Environmental Survey and Site Assessment Program (ESSAP) of the Oak Ridge Institute for Science and Education (ORISE) received 13 water samples collected on September 5, 2001 at the Kerr-McGee Cimarron facility in Crescent, Oklahoma. The samples were initially screened by gamma spectroscopy (Procedure CPI Revision 11) to determine if there was evidence of quantifiable concentrations of gamma emitting radionuclides. Next, each sample was analyzed for gross alpha and beta activity (Procedures APl Rev. 12 and CP3 Rev. 1), isotopic uranium by alpha spectroscopy (Procedures AP3 Rev. 15 and CP2 Rev.
- 10) and Tc-99 analysis (Procedure AP5 Rev. 11 and CP4 Rev. 1).
The gamma spectroscopy screening identified one sample (W003) in which uranium was quantified above the minimum detectable concentration (MDC). No other gamma-emitting radionuclides were identified.
The results for gross alpha and beta, uranium isotopic, and Tc-99 are presented in Tables 1, 2, and 3, respectively.
ESSAP's Quality Control (QC) procedures were followed for these analyses. The daily QC and detector background for the counting instrumentation used in the analyses were within acceptable limits.
Please contact me at (865) 241-3242 or Wade Ivey at (865) 576-9184 should you have any questions.
Sincerely, Dale Condra Laboratory Manager Environmental Survey and Site Assessment Program RDC:WPI:ar Attachments cc:
