Small Amount of Tritium Identified in Water Sample from Connecticut River near Vermont Yankee

No Threat to Public Health or Safety

Vernon, Vt. – As part of its ongoing tritium sampling program, Vermont Yankee learned yesterday that a small amount of tritium, 1230 picocuries per liter, was found in a water sample taken from the Connecticut River adjacent to the plant site on November 3rd. This reading is significantly below the EPA drinking water limit of 20,000 picocuries per liter and has no impact on drinking water supplies.

Follow-up samples taken on November 7 and 10 showed no signs of tritium.

The sampling result is not unexpected given the location of the sampling point and is consistent with the directional flow of groundwater below the plant site. The tritium finding poses no risk to public health and safety.

The State of Vermont Dept. of Health identified a similar reading from their portion of a split sample taken from the November 3rd sample. Split samples are routinely provided to the State Department of Health by Vermont Yankee.

The sample results confirm the Conceptual Site Model that indicates small amounts of tritium would eventually reach the river. Bi-weekly sampling of the river will continue in accordance with the Vermont Yankee sampling plan.

The Nuclear Regulatory Commission and the departments of health in Vermont, New Hampshire and Massachusetts have been notified of the information by Vermont Yankee.
