Indian Point Energy Center EntagyP.O. Box 249 Buchanan, NY 10511-0249 Tel. 914 736-8000 January 4, 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 3H Report showing groundwater sample 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 concentration 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:
  • Temporarily suspending sampling in preparation of the tracer test in January.
  • No changes to the well grouping and status table or to the well group schematic.
