Nova Scotia Sinkhole

 

In August 2018, a sinkhole appeared in Oxford, Nova Scotia, in a community park.  The hole swallowed surrounding trees and picnic tables. (article)

 

 

 

 

Bayou Corne, Assumption Parish, Louisiana (40 miles south of Baton Rouge)

 

One night in August 2012, after months of unexplained seismic activity and mysterious bubbling on the bayou, a sinkhole opened up on a plot of land leased by the petrochemical company Texas Brine, forcing an immediate evacuation of Bayou Corne's 350 residents.  Texas Brine's operation sits atop a three-mile-wide, mile-plus-deep salt deposit known as the Napoleonville Dome, which is sheathed by a layer of oil and natural gas, a common feature of the salt domes prevalent in Gulf Coast states. The company specializes in a process known as injection mining, and it had sunk a series of wells deep into the salt dome, flushing them out with high-pressure streams of freshwater and pumping the resulting saltwater to the surface. From there, the brine is piped and trucked to refineries along the Mississippi River and broken down into sodium hydroxide and chlorine for use in manufacturing everything from paper to medical supplies.  What happened in Bayou Corne, as near as anyone can tell, is that one of the salt caverns Texas Brine hollowed out—a mine dubbed Oxy3—collapsed. The sinkhole initially spanned about an acre. One year later (Aug-2013) the sinkhole covers more than 24 acres and is an estimated 750 feet deep. It subsists on a diet of swamp life and cypress trees, which it occasionally swallows whole. (article & video)

A salt dome is a large, naturally occurring underground salt deposit. Companies drill on the dome's outskirts to create caverns in which to extract brine that is used in the petrochemical refining process, or for storage of such things as hydrocarbons. Officials say a cavern was being mined too close to the edge of the Napoleon Salt Dome, which caused the "unprecedented" side wall collapse. (article)

Additionally as per Deborah Dupre:

 

“The Department of Natural Resources (DNR) had quietly permitted Texas Brine Company LLC to pump radioactive waste into its now failing cavern near the sinkhole DNR also hid documents showing that cavern may have had problems since 2010.”  [radioactive waste = soil contaminated with Naturally Occurring Radioactive Material (NORM) also radioactive oil and gas waste (article) ]

 

“Assumption Parish, an oil refinery haven in the heart of the nation's Cancer Alley, is crisscrossed with oil and gas pipelines.”  (article)

 

“USGS maps show extra movement and stress from oil and gas operations are susceptible to present pressure of a series of earthquakes west of Louisiana, each being where fracking and frack waste injection storage are ongoing.”  (article)
