Re: Ground Water Program Bi-weekly update for 1/18/07

Dear Pete,

Can the NRC get a different report from you. Remember the last time we met, you provided lists of all monitoring well data listed by analyte? Please provide this information to the NRC before each bi-weekly stakeholder call so that we can see other radionuclides besides Sr-90 and H-3. The analytes are: Sr-90, H-3, Cs-1 37, CO-60, Ni-63,and Fe-55. Thanks.

Regards, Jim

Indian Point Energy Center EntagP.O. Box 249 Buchanan, NY 10511-0249 Tel. 914 736-8000 March 29, 2007 Bi-Weekly Groundwater Report Attached is the most recent IPEC Groundwater Investigation Bi-Weekly Update. These reports have been created in order to provide monitoring well data to the stakeholders in a manner that hopefully will assist the reader in understanding the monitoring well data. We will update this report on the alternating Wednesday preceding the scheduled bi-weekly stakeholder call on Thursdays.

This report consists of:

  • An Indian Point facility diagram to help visualize the well locations by functional grouping.
  • A Well Data Table containing technical data on all ground water monitoring wells.

" A listing of the H-3, Sr-90 and Cs-1 37 groundwater sample results received in the last 14 days.

  • A 9°Sr and 3 H Report showing groundwatersample data in graphical and tabular form, historical through present. The sample result uncertainty is presented at three standard deviations. The charts will more easily show data trends and how the data relates to the maximum contaminant level (MCL). The data table will provide all sample results through present, including numerical result, associated sample error (standard dev), the minimum detectable concentration (MDC) and the ratio of result to MCL (fMCL). There will be two pages for each sample location. One page contains Tritium results and the other contains Strontium results.

Highlights of today's report:

  • None Notes of Interest:

a Routine sampling still suspended for tracer test.

  • No new sample results.
  • Added MW-66 to the well group and status table. Changed MW-61 well depth from 200 feet to 50 feet.

e Added MW-66 to the River Front Boundary Well Group in the well group schematic.

  • Removed Teledyne low bias Sr-90 results during August and September 2006 from reports and plots.

Latest Ground Water Well Sample Data Results in pCi/L Last Sample Name Sample Frequency Sample Date Date Returned H-3 Sr-90 Cs-1 37 Notes:

1. ND = (Non Detect). Sample results less than 3 standard deviations or less than the MDC.
2. Sample results shown have been received in the last 14 days.
