He is definitly a fear monger I would leave it at that, he is sensational but so is Mrs. Dupre and I would add enews to that list. Hard to find credible sources on this one but I do believe that if we sift through them all we can find hints of truth. The authorities remain tight lipped and only release enough info to keep people calm.
Oh my gosh! That is paradise. I am truly envious. Now back on topic before I get sanctioned.

They are now saying the bubbles were first recognized in Bayou Lafourche. Bayou Lafourche sits in my backyard, here is a good morning picture of the beauty I wake up to every morning:
The bubbles in Bayou Lafourche is the first I heard of it. Though I myself in my location can not dispute the claims I can say for sure that methane is the least of my worries of pollution in the bayou. Different story for another topic. Bayou Lafourche supplies most of the water for Assumption Parish, Lafourche Parish, and Grand Isle (Jefferson Parish). They never released a boil advisory or warning that the water may be contaminated.
Now on to the methane explosion the sheriff is talking about. Of course there is always a chance of a hydrocarbon explosion when dealing with oil, but the question is to what extent? Would the methane ignite from the location it is leaking from or will it ignite and go down to the methane deposit. I would think with the pressure this methane is pushing it out it would not reach the deposit but be more like a Bunsen burner. Could anyone offer me a little more insight on this?
I just don't know. I feel if there was a true danger then the officials would not let the cane fields be burned.
La. sinkhole methane explosion possible says sheriff, refuting naysayers
– Parish Emergency Declared – 19 June 2012
• Extended 30 days on 9 November, 2012
– Next public briefing – 13 November, 2012 at 7:00 PM / St. Joseph Church
• Texas Brine conducted the following operations on their investigatory well: • Collected a total of 4332.6 bbls(cumulative total as of 8 November 2012) of hydrocarbons from the Oxy 3A Cavern. • Flared a total of 544 mcf of metered gas(cumulative total as of 8 November 2012)
• Air Monitoring Sample Data
– 1 letter (dated 10/18/2012) was released to the parish during this operational period for community ambient air and air at bubble sites sampled 9/28/2012- 10/14/2012 (MultiRAE). Findings-It does not appear that chemical exposure of site-related contaminants poses a public health risk to individuals in the immediate area of Bayou Corne for the time period and chemicals sampled.
– 1 letter (dated 10/18/2012) was released to the parish during this operational period for residential ambient air sampled 9/28/2012-10/13/2012 (MultiRAE); Findings-It does not appear that chemical exposure of site-related contaminants poses a public health risk to individuals in the immediate area of Bayou Corne for the time period and chemicals sampled.
– 1 letter (dated 10/18/2012) was released to the parish during this operational period for air samples collected 9/26/2012 and 10/2/2012 (isotopic analysis); Findings-This data is meant to characterize the gas in the bubbles and wells sampled. These type of analyses do not provide data that could be used for assessing public health.
– SEET has received and is analyzing community ambient air sampled 10/15/2012- 11/4/2012 (MultiRAE). SEET will issue a letter to the parish in reference to these findings once the review of the data has been completed.

• Industrial Water Well Sampling Data – 1 letter (dated 10/18/2012) was released to the parish during this operational period for industrial wells sampled on 9/26/2012. Findings-DHH recommends immediate remediation of industrial water wells with high levels of methane.
– Safe Drinking Water – 1 letter (dated 10/18/2012) was released to the parish during this operational period for two privately-owned water wells sampled on 9/26/2012. Findings-DHH recommends property owners routinely monitor for the presence of methane in the tested water wells.
– As of 06 November, Texas Brine has removed 123 roll off boxes hydrocarbon contaminated debris. – As of 06 November, Texas Brine has removed approximately 1535 Barrels of hydrocarbons from the surface of the sinkhole.
Next Operational Period (8-13 Nov 2012) Incident Action Plan
– Pursant to the DNR press release dated 11/7/2012 regarding the pressure in some geoprobes, LDEQ will conduct indoor air monitoring as requested at residential homes in the Bayou Corne community.
Texas Brine, LLC UPDATE November 8, 2012
1. The Observation Well is shut in today. A total depth measurement of the cavern floor was conducted today, the results of which will be reported on Friday. The controlled removal of liquid hydrocarbon from cavern #3 will be conducted on Friday as well.
2. There were no observable changes in the sinkhole’s characteristics. Only a minimal amount of liquid hydrocarbon now remains on the sinkhole surface. Skimming operations have been turned to the removal of hydrocarbon material from the surface of the shallow water in the treed areas on the sinkhole perimeter.
3. Flaring of natural gas from the shallow aquifer relief well continues on a 24- hour basis. As of 8:00 a.m. today, just over 100,000 cubic feet of natural gas has been vented from aquifer and safely flared at the surface.
Natural gas detected closer to community near sinkhole than previously thought
New data shows natural gas much closer to the Bayou Corne community of Assumption Parish than previously detected. Officials said the additional testing is out of an abundance of caution. Shallow-depth wells near the community are now indicating natural gas pressure 20 to 40 feet beneath the surface. That's much shallower than previously reported. It's still not really know what the natural gases relationship is with the bubbling in the bayou. "The monitor is only a foot away from where the bubbling is. There's no explosive limit just a foot away from the bubbling. So as far as any distance from here, there's no concern for that to happen," said John Boudreaux, director of the Assumption Parish Office of Emergency Preparedness.
Texas Brine, LLC UPDATE November 9, 2012 1. The Observation Well was opened this morning for two hours during which approximately 60 barrels (or 2,520 gallons) of liquid hydrocarbon were displaced from cavern #3 to the surface. Results from yesterday’s measurement of the total depth of the cavern revealed that the cavern floor has risen another four feet since last measured on November 1. The next total depth measurement will occur next Thursday, November 15.
2. Only a small amount of hydrocarbon remains to be removed from the surface of the sinkhole. The surface will be carefully monitored to see if any additional oily material accumulates. Skimming of the small amount of liquid hydrocarbon material observed in the tree-filled swampy area bordering the sinkhole continued today.
3. Between 8:00 a.m. yesterday and 8:00 a.m. this morning, another 34,000 cubic feet of natural gas was vented from the shallow aquifer relief well and safely flared at the surface. The venting and flaring continues 24 hours a day.
State bills Texas Brine $3.5M for sinkhole costs
BATON ROUGE, La. (AP) - The state has sent a $3.5 million bill to the Texas company it blames for a massive sinkhole that has swallowed more than 5 acres of land in Assumption Parish and contaminated an aquifer.Attorney General Buddy Caldwell sent a letter this week to lawyers for Texas Brine demanding payment, saying it's the tally so far of state response efforts to the sinkhole.
Texas Brine spokesman Sonny Cranch says the company hasn't received a detailed accounting of the costs included in the $3.5 million and will request an explanation of the costs before addressing "the issue of payment in the appropriate manner."
