BAYOU CORNE, LA (WAFB) -

According to the Assumption Parish Police Jury website, Texas Brine has reported high levels of Hydrogen Sulfide from their sonic vent well that is drilled into the cap rock at the giant sinkhole near Grand Bayou and Bayou Corne.

Hydrogen Sulfide is a poisonous, flammable gas and has a very bad odor. The smell is described as the smell of rotten eggs. Unlike methane, it is heavier than air and collects at low to the ground levels. No community air monitors have detected Hydrogen Sulfide.

The well was shut down due to these levels. This vent well is the deepest vent well on the property. The Department of Natural Resources' contractor, The Shaw Group, is currently investigating. Assumption Parish officials are currently waiting on additional details from DNR.

The primary initial purpose of the well was to gain direct access to the interior of the abandoned brine cavern so that equipment can be sent down into the cavern to determine the stability, internal pressure and contents of the cavern.

The top of the cavern lies about 3,400 feet below the surface. Venting natural gas is a part of the plan to deal with the cause of the sinkhole and natural gas bubbling in the area.

DEQ and Assumption Parish OEP will continue its daily monitoring of the air quality and gas bubbles to make sure levels are safe.
