Sinkhole discovered at Hanford Tank Farm

Sinkhole Discovered

RICHLAND, Wash. -- A sinkhole with an opening approximately 2 feet in diameter was discovered Thursday morning inside the SX Tank Farm at Hanford.

It was observed while soil compaction work was underway near Tank SX-108.

We're told the depth of the cavity has not been determined.

Washington River Protection Solutions officials tell Action News they plan to use a special camera to inspect the hole and inside the nearby tank.

Work inside the farm was stopped and personnel left the farm according to procedure.

Radiological surveys conducted in the farm yesterday found no contamination and no significant increase in radiation readings.
