-- JJJU P.O. Box 249 Buchanan, NY 10511-0249 Tel. 914 736-8000 December 7, 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 by functional 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 9°Sr 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:

No new results have been received in the last 2 weeks.

Several new wells were sampled. These include MW-60 and MW-62.

Drilling has been completed in MW-61.

" The initial sample from MW-63-191, collected on 10/2/06, showed a positive Cs-1 37 result of 27 pCi/L.

We received the report from Teledyne on the results of their low bias investigation on 12/6/06. The report is under review. Until the Sr-90 low bias problem at Teledyne is resolved, no new samples are being shipped to Teledyne for analysis and many Sr-90 results for samples collected in August and September are considered as suspect. All new samples are being sent to a different laboratory.

We suppressed the initial Sr-90 results for three samples: MW-53-80-(001), MW 78-(001) and MW-57-45-(001) based upon an analysis of a 500 mL aliquot from the original samples. The results of the 500 mL aliquots were comparable to both the ORISE and Wadworth labs. Only the results of the 500 mL aliquots show up in the database.

Notes of Interest:

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

1. "Prelim Sr is an analysis that provides an initial approximation of strontium concentration. "Sr-90" results are

the official concentrations and should replace the initial "Prelim Sr" result.

2. ND - (Non Detect). Sample results less than 3 standard deviations or less than the MDC.
