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. [...]
