SUBJECT:

REPORT FOR ANALYSES OF TEN WATER SAMPLES FROM YANKEE ROWE IN ROWE, MASSACHUSETTS

[TAC #: L52675] [RFTA NO. 06-0011

Dear Mr. Hickman:

The Oak Ridge Institute for Science and Education (ORISE) received ten water samples on December 15, 2006 associated with Yankee Rowe in Rowe, Massachusetts.

Sample analysis was initiated based on the sampling plan received on November 29, 2006. Sample identifications and collection data for the samples addressed in this report are presented in Table 1. The garmna spectroscopy, gross alpha and beta, carbon-14, tritium, and total radiostrontium data are provided in Tables 2-6, respectively.

The pertinent procedure references are provided in the tables.ORISE's Quality Control (QC) requirements were met for these analyses.

The QC files are available for your review upon request. The letter report was delayed because of higher priority analytical work submitted by Region I.My contact informnation is listed below. You may also contact Wade Ivey at 865.576.9184 with any questions or conmments.

Sincerely, 0"L Dale Condra, Manager Laboratory RDC:\XPI:
