-- Ljlntfif a P.O. Box 249 Buchanan, NY 10511-0249 Tel. 914 736-8000 December 21, 2006 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 byfunctional grouping.

• A Well Data Table containing technical data on all ground water monitoring wells.

• A listing of the most recent groundwater samples for which results are available.

• A 90Sr and 3H Report showing groundwater sample data in graphical and tabular form, historical through present. 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:

" New results have been received in the last 2 weeks.

• Drilling has been completed in MW-61.

• Low levels of Cs-137 were detected in MW-58-26 (72.7 pCi/L), MW-59-45 (37.4 pCi/L) and MW-59-68 (114.8 pCi/L).

Notes of Interest:

" Temporarily suspending sampling in preparation of the tracer test in early January.

" Tentative start date for the tracer test is January 9, 2007.

• The sample result uncertainty is now being presented at three standard deviations.

This is in comparison to the previously utilized two standard deviations. This was done to provide consistency between both the NRC and IPEC's off-site lab as to what constitutes a positive result.

• The Latest Sample Results Report now lists "Cs-137" instead of "Prelim Sr". Prelim Sr was an analysis that provided an initial approximation of the Sr-90 concentration.

We no longer are requesting this analysis.
