One of the two vent wells have been shut down and will be capped. Traces of hydrogen sulfide detected in the equipment. This is no good, no good at all. I will post a link as soon as one comes up.

Human Data Inhalation Exposure to concentrations of about 700 mg/m 3 (500 ppm) hydrogen sulphide and above may be fatal. Respiratory failure was the most common cause of death, but a wide range of health effects have been reported following exposure to high concentrations including respiratory, neurological and cardiovascular effects [1, 2]. Neurological effects at high exposure have included nausea, headache, delirium, disturbed equilibrium, poor memory, neurobehavioral changes, olfactory paralysis, loss of consciousness, tremors and convulsions. In those surviving exposure to high concentrations some of the neurological effects may be permanent or persistent. Cardiac irregularities including arrhythmias as well as hypertension have been reported [1, 2].
IDLH : 100 ppm
May cause damage to the following organs: lungs, upper respiratory tract, eyes, central nervous system
Gas. - COLORLESS LIQUEFIED COMPRESSED GAS WITH A ROTTEN EGG ODOR, BUT ODORLESS AT POISONOUS CONCENTRATIONS. NOTE: SENSE OF SMELL BECOMES RAPIDLY FATIGUED AND CAN NOT BE RELIED UPON TO WARN OF THE CONTINUOUS PRESENCE OF H2S.
Status of Hydrogen Sulfide in Bayou Corne Area
Prepared by Gary R. Hecox, Ph.D., Shaw Environmental & Infrastructure, Inc.
Shaw Environmental & Infrastructure, Inc. (Shaw) has reviewed existing data and is currently collecting new data to evaluate the conditions related to the hydrogen sulfide observed in the Texas Brine Relief Well #2 completed in the cap rock. At all times, protection of local residents and project staff is and will remain the top priority when making decisions and recommendations for response activities related to site conditions.
At this point in time, it appears that the hydrogen sulfide produced by Relief Well #2 was only from the cap rock and not the alluvial aquifer vent wells. While low concentrations of hydrogen sulfide have been detected at some of the bubble sites, the concentrations are well below those that would pose a human health risk. Other than Relief Well #2, all hydrogen sulfide concentrations measured are consistent with the production of hydrogen sulfide caused by decay of trees and other vegetation in a swamp environment.

Last night the MANY residents caught the bad odor smell. Some saying the strongest they have yet to smell. It was also accompanied by a few tremors. Will post with updates as soon as I get it.
They are trying to seal up the well which H2S was detected. THAT WILL BE THE BIGGEST FREAKIN MISTAKE! The HS2 will then have no choice and take the next path of least resistance.... the aquifer. THIS IS GETTING STUPID DOWN HERE!
