Workers are starting to clean up what’s believed to be some of the most hazardous waste at the Hanford nuclear reservation.
The Tri-City Herald reports test pits have been dug in 12 trenches that were filled in the 1950s and ’60s in a 6-acre area called the 618-10 Burial Ground.
Washington Closure officials say the site is believed to hold high-level waste, but disposal records are incomplete. Clean-up is scheduled for next year. (AP)
