For the people of Bayou Corne, a small community in northern Assumption Parish, the first signs of trouble appeared in late May. Streams of bubbles appeared in the water in nearby Bayou Lofourche. Then in early August a series of tremors led to the discovery of a sinkhole. Since then that hole in the ground has continued to grow along with the concerns of local residents and the officials they are looking to for answers.

Louisiana’s Assumption Parish sinkhole caused the evacuation of 150 homes in early August and continues to threaten the area with possible explosions due to methane gas pockets. Property owners have not been allowed to return home yet, and businesses are at risk.
Texas Brine Co. began burning off natural gas Friday that was trapped in a water aquifer near a sinkhole in northern Assumption Parish, officials said.
This was the first time state, parish or company officials have been able to get gas to flow from four “vent wells” driven into the ground around the sinkhole in order to draw the dangerous gas out of the aquifer.
Located in the swamps between Bayou Corne and Grand Bayou south of La. 70 South, the sinkhole is more than 5½ acres in size at the surface and has prompted authorities to issue a standing evacuation order on Aug. 3 applying to 150 homes.
Fears that the trapped gas, which is colorless, odorless and potentially explosive, could accumulate to dangerous levels at the surface has further justified the evacuation order, parish officials have said.

Salt is a strong electrical conductor. Ocean water is full of salt. Once the salt dries, it can wreak havoc as power utilities restore electricity.
Several small explosions rattled storm-weary residents of Peter Cooper Village late Friday night and even blew two manhole covers as Con Edison was restoring power to the area. The latest apparent nastiness from Hurricane Sandy — days after the nightmare storm — caused no injuries, according to paramedics and Con Ed officials on the scene. Officials said the explosions occurred when the utility started restoring electricity and the current hit salt on the power lines. The salt was the remnant of a 10-foot wave of East River water that crashed through the complex at the height of the storm Monday.

Gas hissing, fires, possible explosions. These are just some of the post-hurricane flood worries plaguing New Jersey residents.
On the long and slender stretch of New Jersey barrier beaches that includes Brick Township, the hiss of gas seems to be everywhere. And between gas fires and the ocean surge, dozens of homes have been destroyed – 60 in Brick Township alone.
The threat from gas is widespread and the risk of further fire and explosion continues along this devastated coastline where many homes were lifted from foundations and their gas lines ruptured. And officials say it will continue until flames are brought under control and utilities are able to turn off the main gas line serving the two barrier islands on this stretch.
