An underground tank holding some of the worst radioactive waste at the nation’s most contaminated nuclear site might be leaking into the soil.
The U.S. Energy Department said workers at Washington state’s Hanford Nuclear Reservation detected higher radioactivity levels under tank AY-102 during a routine inspection Thursday.
Spokeswoman Lori Gamache said the department has notified Washington officials and is investigating the leak further. An engineering analysis team will conduct additional sampling and video inspection to determine the source of the contamination, she said.
State and federal officials have long said leaking tanks at Hanford do not pose an immediate threat to the environment or public health.
