New seismic activity at huge sinkhole tied to Houston company

Two cracks have appeared in a containment berm around a huge Louisiana sinkhole tied to a Houston-based company.
The cracks, reported Oct. 30, have halted activity at five or six wells that were put on the berm to help ventilate the sinkhole and provide observation spots, said John Boudreaux, director of the Assumption Parish Office of Homeland Security and Emergency Preparedness.
"The (observation) work outside of the immediate sinkhole continues," Boudreaux said Friday. "There's 40-some vent wells but only five or six on the containment berm."
The wells also offer a means of sampling for contamination, he said.
Texas Brine Co., whose corporate headquarters is in Houston, is named as a defendant in a class-action lawsuit filed in August by residents who had to evacuate their homes last year because of the sinkhole.
According to the suit, a sinkhole measuring 422 feet deep and 273 feet wide appeared Aug. 3, 2012, in the wooded swamp near Bayou Corne in Assumption Parish.
