Cleanup continued outside the Veterans Administration Medical Center Saturday, but officials say it may take awhile before all traces of the carcinogenic PCBs are removed.

"It's going to be a long-term cleanup," said Salt Lake Battalion Chief Gordon Nicholl. The task of cleaning up the toxic material has been turned over to Ridell Environmental Services, a private company."They went in and scrubbed the hospital out where they had been tracking it through," Nicholl said. One corridor of the hospital would be scrubbed again.

More than 100 yards of asphalt outside the hospital will be torn up and disposed of at a hazardous waste site, probably in Texas.

Ridell officials continued to test areas of the hospital for traces of PCBs and had to borrow some testing kits from the county fire department.

Workers trying to drain the PCBs from a hospital transformer apparently tipped over a drum on the hospital's loading docks Friday afternoon. The contaminated area is secured and there is no threat to patients as the cleanup continues, said Helen Natrigo, medical administrative assistant at the hospital.

Nine people were exposed to the PCBs and were scrubbed down in the hospital's nuclear medicine decontamination shower. None were admitted to the hospital. Six automobiles were impounded for testing.
