  1. Is this the first time a sinkhole happen on or near a salt dome ?

    Bayou Corne and the Grand Bayou sit atop the Napoleon Salt Dome, which covers a one by three mile area and has 53 caverns.

    This isn’t the first time this has happened.
    On the way to Bayou Corne, you pass through Grand Bayou and notice concrete slabs — foundations of what once were homes of a Grand Bayou community.
    In 2003, a Dow Chemical storage cavern in the Napoleonville Salt Dome lost contents into the subsurface and gasses vented into homes.

    Just what are they talking about ?
    Installing aquifer monitoring well MRAA 09D (southeast of Oxy 9 well pad
