Work resumed at Hanford's landfill for contaminated waste Monday after an area with suspicious material was isolated.
Work stopped last Tuesday on disposal of waste and construction of an expansion of the Environmental Restoration Disposal Facility. Workers were concerned after they smelled a sulfuric odor and saw what appeared to be dust or smoke while a container was being dumped.
The area was temporarily covered with geotextile material and soil so work could continue at the landfill while an investigation in underway.
The landfill is key to Hanford environmental cleanup, receiving about 300 truckloads of waste a day.
