Neighbors are concerned about the large bubbles that have arisen from the manure lagoon at Tony Goltstein’s dairy in Winchester, Ind.

According to The Wall Street Journal, the bubbles are the size of small houses.

The bubbles appear to be caused by giant pockets of methane trapped under plastic liners of the lagoon. 

Neighbors are reportedly concerned that if Goltstein pops the bubbles, it will cause an explosion of manure and toxic gases.

The latest word is that the Indiana Department of Environmental Management has given the farm permission to release the gas in a controlled manner, using valves attached to the bubbles. Read more.
