Expert: Gas sources feeding Assumption aquifer

NAPOLEONVILLE, La. (AP) - A state seismic expert has found two likely existing "deep" sources continuing to feed methane gas under the Bayou Corne and Grand Bayou communities in the area of northern Assumption Parish.

But officials working on the removal of the gas, a suspected byproduct of the formation of the Bayou Corne-area sinkhole last year, said Tuesday they are focused on cutting off or removing gas in two shallower layers first while they work on how to eliminate these two deeper sources.

During the parish community meeting Tuesday where the new seismic results were revealed, The Advocate reports some residents complained that response officials had not gone after the deep sources first.

Gary Hecox, CB&I hydrogeologist and leading scientist on the sinkhole response, said drilling for the sources is certainly viable.
