Underground gas storage tanks normally fail from rust perforation in the interior of the tank, thanks to many effects of water within the tank containing, in the case of heating , mix of water using sulphur in the gas.
If storage tank manufacture test indicates there is plenty of water at a buried oil tank an individual would be pessimistic about its life. It causes tank collapse by rust penetration by the interior. Additionally, there can be a bacteria residing in tanks, present at the water/oil port, trapping organics and amino acids.
The corrosiveness of the action is often most important at the water-oil port at the tank, which explains why a few tank leaks will grow not in the exact base of this tank (but seem there also ) but alternatively, a couple inches upward, along the face of the tank.
The elevation of the rust line across the surfaces of the interior of the petroleum storage tank is dependent upon the total amount of water from the tank and so the place of this water/oil port line on the face of the tank.
