RICHLAND — The Washington State Department of Ecology is investigating a report of potentially contaminated liquid dumped into the ground at the Hanford Nuclear Reservation in August.
The Tri-City Herald reported Friday that Department of Ecology spokesman Randy Bradbury said that initial analyses of soil samples collected where the liquid was dumped found no contamination above background levels.
Washington River Protection Solutions, the Hanford nuclear reservation’s tank farm contractor, notified the state of the incident, but not until a couple of weeks after it happened. Bradbury said it is required to report incidents immediately.
Tank farm contractor spokesman Peter Bengtson said the tank farm contractor believes it did not violate state regulations.
