Groundwater Investigation The New York State Department,of Environmental Conservation (DEC) and the New York State Department of Health (DOH) have been participating in the ongoing groundwater investigation of radionuclide contamination in groundwater under the plant, and the release of that water to the Hudson River. The purpose of our involvement is to protect the interests of the citizens and the environment of the State of New York by helping to ensure that Entergy performs a timely, comprehensive characterization of site groundwater contamination, takes appropriate actions to identify and stop the sources of the leak, and undertakes any necessary remedial actions.

-~IIEnhanced Fish Sampling
- DEC and DOH worked with IEntergy and the NRC to develop lthis year's enhanced fish sampling leffort. The intent is to meet these I
three goals: 1. develop a more scieFltifically rigorous sampling program, 2. evaluate the iappropriateness of Entergy' s Ilenvironmental background (control) location, and 3. perform a thorough ievaluation of this potential human lexposure pathway. To accomplish this:
Sampling focused on species that do not migrate over significant distances in the river and are expected to be present at all sampling locations, or are of commercial or recreational importance, including striped bass, l;>lue crab, carp, white perch, American eel, catfish, and sunfish.
Samples were collected from the area near Indian Point, the existing upstream control area near Roseton, and from far-upstream near the Village of Catskill. (see map)
Samples of edible portions of each species at each location are being analyzed by NYS, NRC, and Entergy~
Bone samples are being analyzed by NYS.
Both flesh and bone are~being analyzed for Sr-90 and gamma emitting radionuclides.
NYS will review the data to assess the current environmental monitoring program, and to evaluate any potential impacts to public health and the environment.
Fish Results to Date NRC fish results have been received and show no detectable Sr-90 or gamma emitter~. Entergy and State analyses, are not yet available from our respective labs, but will be reported to stakeholders when received.
Regulatory Authority The federal government regulates the use of radioactive materials at Indian Point under the federal Atomic Energy Act.
At present, there are no off-site groundwater impacts, and releases of contaminated groundwater to the river do not violate state surface water standards for H-3 (20,000 pCi/I) and Sr-90 (8 pCi/I).
Remedial Actions Tritium Because tritium (H-3) is actually an isotope of hydrogen, it is not
, feasible to remediate H-3 contaminated groundwater other than by removing the source of contamination. Entergy has identified a leak in a portion of the Unit 2 SFP (a probable source of the H-3 plume) and will repair this leak (and any others discovered) after completion of its inspection of the stainless steel liner.
Strontium Unlike H-3, Sr-90 contamination can be removed from water through readily available treatment processes. Entergy has reduced the source of the Sr-90 plume by >97%
through operation of a water treatment system in the Unit 1 SFP.
This has resulted in measurable
~eductions in Sr-90 groundwater concentrations. The company has also agreed to remove the spent fuel and remaining contaminated water from the Unit 1 SFPin 2008, stopping the contamination source.
The agencies will be monitoring the progress of these source remediation efforts closely and will be reviewing and commenting on the final site hydrology report and long-term monitoring plans Entergy is anticipated to finalize in the next couple of month.
