Thanks to ALL who wrote, called, e-mailed and went to the committee hearings…. especially to LEAN and Save Lake Peigneur‘s Herculean efforts to stop the ruin of Lake Peigneur and the aquifer. A rum punch is in order!
“the salt, though like rock, is fluid. The rate of creep is slow but has a high variability to it. The salt is compressed from the weight above, and this pressure is manifested in all directions, sort of like when you pressurize water. So when you hollow it out, there is tremendous pressure, like a truck pressing in on each square inch. This enormous pressure slowly fills the void from all directions.
Imagine that there is the gas/atmosphere that also gets pressurized and would surely be escaping through the smallest egress. Explosive gas at high pressure…this is one reason they back fill and plug with concrete as they go.
The reason there are salt dome formations is because the salt is less dense compared to surrounding rock and it slowly “floats” toward the surface in balloon like shapes. This would eventually…eons… bring the waste with it to the surface, if it could burst through cap rock and whatever.”
