The EPA’s current limit for tritium in public drinking water is 20,000 picocuries per liter (A picocurie is a unit of radiation.
A liter is just under one-fourth of a gallon.) which corresponds to a lifetime fatal cancer risk of about one in 25,000 for a person drinking two liters a day for a lifetime.
This is far less protective than a one-in-a-million risk level, the most stringent standard for cleanup for a single pollutant at Superfund sites containing radioactive waste.
There have been two tritium leaks at Prairie Island, including one unmonitored leak of 3,700 gallons of water on November 30, which was not reported until February
This is unacceptable, especially since the NRC report acknowledged that there was potential for the liquid to contaminate local groundwater.
And recently a smaller leak was reported, but this time the concentration of tritium was much higher at 15,000 picocuries per liter. Unfortunately these events fit into a pattern of tritium leaks at many reactor sites, despite which the NRC and the reactor operators have not yet put in place an adequate system of reporting or monitoring.
