On Weeks Island in New Iberia Parish there was an incident that is useful to know about. They had a sinkhole problem there and they fixed it it. The solution included a “freezewall“. Read about it here (15 page doument) –
It is a big lie when Texas Brine claims their sinkhole problem has never happened before in history. They could have read up on this conference in nearby Gatlinburg, Tennessee, April 2-5, 1995, Karst GeoHazards: Engineering and Environmental Problems in Karst Terranes Proceedings of the Fifth Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst.
The document is also archived now on the Salt Dome page.
