VEDO (07 October 2012) LA Sinkhole " Explosive Concentrations"

Officials: Pressure building in aquifer to "explosive concentrations"? Geologists say top layer may not hold back gas if above 75 psi — New footage inside giant sinkhole (VIDEO) enenews.com Title: Gas trapped near sinkhole Source: The Advocate Author: David J. Mitchell Date: October 07, 2012 An as-yet undetermined amount of natural gas is trapped in the aquifer underneath the Bayou Corne community, state and parish officials have said. [...] some parish officials say they are concerned the odorless, colorless gas underground could accumulate unseen to explosive concentrations if left unchecked. John Boudreaux, director of the Assumption Parish Office of Homeland Security and Emergency Preparedness, said there are concerns the gas can build up pressure under the clay layer that lies above the aquifer. Once the pressure in the aquifer reaches a pressure greater than 75 to 85 pounds per square inch, the clay layer might not be able to hold back the accumulated gas, according to Boudreaux and geologists. "And then it could be a problem because you do not know where the weak point would be until after it has already done its thing," Boudreaux said. [...] Our first report on the pressure build-up in the aquifer was 45 days ago: Officials: Sinkhole measurements unavailable — Police want study of "simultaneous venting of the aquifer as the exploratory rig is being drilled" See also: Officials: Gas pressure is increasing in aquifer near giant sinkhole — Trying to relieve buildup <b>…</b>
