| event text = On February 26, 2015, as a result of routine monitoring well sampling, Palisades Nuclear Plant identified tritium in temporary wells 7 and 8, located within the plant protected area. Tritium concentrations were less than the threshold value (20,000 pCi/L) for initiating voluntary communications in accordance with Nuclear Energy Institute Ground Water Protection Initiative. The station promptly isolated and rerouted the likely source. Subsequent sample concentrations from samples obtained on March 18, 2015, have resulted in concentrations of tritium less than the minimum detectable activity. The wells are currently used only for on-site sampling and not for drinking water. There is no threat to public health and safety. | | event text = On February 26, 2015, as a result of routine monitoring well sampling, Palisades Nuclear Plant identified tritium in temporary wells 7 and 8, located within the plant protected area.

These results confirm that a leak from the pipe that runs from the turbine sump oil separator to the turbine building drain tank was the likely cause. The volume of the leak cannot be determined but is potentially greater than 100 gallons. Therefore, voluntary communications have been made to state and local stakeholders. The Licensee has notified the Michigan Department of Environmental Quality, Van Buren County Administrator, the Township Supervisors in Covert, Geneva, and South Haven Townships, as well as the City of South Haven Mayor and City Manager. | These results confirm that a leak from the pipe that runs from the turbine sump oil separator to the turbine building drain tank was the likely cause.
