BAYOU CORNE, LA (WAFB) -

There is new information being released about recent bubbling in a bayou near the massive sinkhole in south Louisiana.

Texas Brine, the company responsible for the sinkhole, reported scientists determined the new bubbling site is the result of swamp gas and is not related to the giant slough in nearby.

The bubbling site is located in Grand Bayou off LA 69.

A sample was taken from the bayou two weeks ago.

Swamp gas is caused by a natural breakup of organic materials.

History of the Sinkhole

The sinkhole opened up in August 2012 and was roughly 1/24 of the size it is now. The sinkhole formed when an underground salt cavern collapsed.

In the past, seismic activity is reported, then the sinkhole burps up debris and then a slough-in happens. Burps occur when air and gas from deep in the sinkhole bubbles up. It can cause debris and an oily substance to float to the top. A slough-in is when the sinkhole swallows trees and land that is on the edge of the sinkhole.

Berms were placed around the sinkhole shortly after it opened up to keep the oily, debris filled water contained to the sinkhole area so it would not contaminate the area bayous.

It has more than a year since hundreds living near the giant sinkhole were forced from their homes.

Bubbles were spotted in Bayou Corne and Grand Bayou in June 2012. Two months later, the ground opened up and left what is now a 24-acre sinkhole. Residents were evacuated and the most affected residents began receiving weekly checks from Texas-Brine in the amount of $875 per week. Texas Brine owns the salt cavern that collapsed, causing the sinkhole.

On August 2, Gov. Bobby Jindal and Attorney General Buddy Caldwell announced the state will be suing Texas Brine for environmental damages caused by the failed Texas Brine cavern.

Parish and Texas Brine officials agree the situation is far from over. 3D seismic surveys show the sinkhole itself it beginning to slow and stabilize, but the recovery is focused on another danger; natural gas gathering underneath a nearby aquifer.
