Spill in China Brings Danger, and Cover-UpBy JIM YARDLEY
Published: November 26, 2005
HARBIN, China, Nov. 25 - A toxic 50-mile band of contaminated river water slowly washed through this frigid provincial capital on Friday, leaving schools and many businesses closed, forcing millions of people to spend a third straight day without running water and raising fears of a long-term environmental disaster. --snip--
The city tried to convince the public that a shutdown was necessary to conduct routine repairs on the pipes. Suspicions instantly erupted.
There had already been an inexplicable rash of rumors that the government had detected signs of an earthquake. Now those rumors escalated, and enough people panicked that officials had to confirm the spill, but the public relations damage was already done.
It seems that in their efforts to hide a chemical spill, Harbin officials may have helped fuel unfounded fears of an earthquake. The provincial earthquake bureau has since issued a reassuring statement that no temblors are predicted.
