BAYOU CORNE, La. — People living in Bayou Corne got a first hand look at the equipment Texas Brine contractors plan to use to get a better picture of what's going on under the ground.
Residents, who've been evacuated from their homes for more than six months, say it's sign of progress.
There are several pieces of equipment that will be used to complete seismic monitoring tests. Vibroseis trucks or "vibe trucks" will be the most visible sign of testing in the community.
"The beauty of this is that they can collect the data on the existing roadways and right of ways, so this will be used on the streets of Bayou Corne," Sonny Cranch, Texas Brine representative, explained.
Texas Brine officials say the vibe trucks will shoot two ten second waves of sound into the ground then move to the next spot.
"Once they've done that sweep at a location they will move maybe fifty feet to another location, but more often then not they only have to do this once," Cranch described.
Residents came out Saturday to get a look at the testing equipment before it gets put in their neighborhoods.
"I don't anticipate any problems here we just need to get it done, so that we can find out what's going on below the surface of the earth here," Dennis Landry, Bayou Corne resident, said.
Scientists will be monitoring a 2.58 square mile area in Bayou Corne through Mid April. Texas Brine officials say so far they've received mostly positive feedback from residents.
"They understand that it's not an invasive process. It's not going to destroy their residences, and it's absolutely necessary to get this clear image of this geological structure from the surface down to 7 thousand feet," Cranch said.
Residents are ready to get the testing started.
"Somethings at first nobody knew exactly what was going on nobody knew exactly what to do. Now there has been a big change in the last few weeks there seems to be lot of direction for what's going on. They're getting a lot of work done you know," Landry explained.
Cranch said contractors will use two other methods in uninhabitated swampy areas to do seismic testing. Pentalite will be sent 40 feet into the ground and vibrations will record data that can later be used to paint a picture of under the surface. Contractors will also use air guns to test in more swampy areas.
