Officials to test Leadville warning sirens amid tunnel threat

LEADVILLE, Colo. ” Federal officials say they’ll test warning sirens in Leadville this week as they prepare to fix a partially collapsed drainage tunnel where more than a billion gallons of water is trapped.

Lake County officials have declared a state of emergency for fear that growing pressure in the tunnel could cause a catastrophic blowout and flood the town.

The tunnel drains contaminated water from abandoned mines.

The siren test will be Friday starting at 5:30 p.m.

Federal officials plan to pump water from the ground to ease pressure on the tunnel. They hope that will give them time to repair the tunnel and pump the backed-up water to a treatment plant.
