I don't know what the geology there is , but in fla peninsula and panhandle, the underlying rock is very porous limerock. Over here typically the sinks are formed from the interaction of water ( or lack of) and eroded limerock. Sandy soil, very porous overlying limerock, some areas along water will have wet sandy clay


So up down sideways through shifts and openings, cracks. A salt dome sounds like a plenty porous structure. I would assume on paper at least it has some durability since they have been allowed to store in it, but common sense does not always prevail.


no. the brine company pumped out hundreds of thousands of gallons of stuff, until they struck gas and bugged out.
