BAYOU CORNE, La. (AP) - Officials say explosive concentrations of gas have been found in soil underneath two homes and a shed in the Bayou Corne community near a large sinkhole.
Workers with Texas Brine Co. contractor Tetra Tech drilled small holes through the slabs and collected the gas Tuesday through a quarter-inch tube from the top one to two inches of soil underneath.
Assumption Parish officials tell the Advocate the gas appears to be of a sufficiently low pressure so as not to migrate through the slabs to pose an explosive risk inside structures.
Scientists say the sinkhole formed Aug. 3 after the failure of an underground salt cavern operated by Texas Brine, which extracted brine and piped it to nearby petrochemical facilities.
