Dominion Virginia Power is seeking the source of leaking radioactivity at its North Anna nuclear power plant after an elevated level of tritium was detected in groundwater.

Company spokesman Rick Zuercher tells the Richmond Times-Dispatch (http://bit.ly/A8e2lf ) that the plant's two reactors aren't the source of the leak.

Dominion Virginia Power also told the commission that there's no evidence the leak is related to last year's 5.8-magnitude earthquake.

The commission says the radiation isn't a hazard to the public.
