Giant Gas Bubbles in Indiana Dairy Farm’s Waste Pond Frighten Neighbors

Well, the crisis is over:

WINCHESTER, Ind.—Several giant bubbles on a dairy farm manure lagoon were popped Thursday, emitting a pungent stench that wafted across fields on a warm spring breeze.
There were no explosions, as some neighbors had feared, when several engineers floated around farmer Tony Goltstein’s manure-storage pond in a flat-bottomed boat and released gas from the bubbles. The bubbles, the size of small houses, were inflated with gas released by 21 million gallons of decomposing cow manure.
The bubbles were deflated with a device fitted with a tube and a valve that allowed for a controlled release of the gas. “The facility is venting,” said Bruce Palin, an Indiana state environmental official. “So far, there have been no big booms or explosions.”
