Minnesota officials are monitoring the cleanup of a 400,000 gallon leak of contaminated water from a nuclear power plant in the city of Monticello run by the energy giant Xcel Energy. Officials said there is no danger from the leak.

The leak was detected nearly four months ago and reported to state and federal regulators. The federal Nuclear Regulatory Commission posted a notice publicly at the time, but the company and state agencies did not notify the general public until last week.

“Xcel Energy took swift action to contain the leak to the plant site, which poses no health and safety risk to the local community or the environment,” the company announced in a statement on Thursday. Ongoing monitoring has confirmed that the leak “is fully contained on-site and has not been detected beyond the facility or in any local drinking water,” the company said.
