If the ground underneath gets damp the tank may lean over and maybe fall over.

This is because they are intended to be stacked 3 units high when full, so you know that they have the strength.
That being said, working with what you have is different.
Because of way the bottom of the tote is built, I think you need a platform with a bigger footprint than the tote itself.
If you stacked 6 pallets ,three pallets high , you could have a strong platform that was roughly 48"x80" and a little more than 12" off the ground.
I would not encourage any use of the other materials. Creosote treated wood is a known carcinogen, so any cutting or drilling would put you in danger.

As suggested, cross arms from free wood will spread the load and lift the tank.
I would ask you to rethink the use of Creosote, it is bad stuff, no matter what cash you save with timber.
Can I suggest you find a marketable solution to the dumpster for the timber?
If your companies agrees you may be able to sell the timber and buy good poles, or you can use the timber in different ways that do not involve being poked into the ground?
Stirrups can be used with shedding, concrete collars for posts in the ground.

Creosote is one of the main components of the chemical cocktail that renders rail lands the equivalent of superfund sites.
If your concern is eliminating the problem, I would figure out how to build an incinerator hot enough to crack the creosote into its constituents, leaving only charred wood. I would then figure out how to monetize the heat, probably with another heat-based industrial process, and/or a heat engine-based power generator.
My concern with using the creosoted wood as I have seen it used in the past is that water infrastructure invariably leaks, which is why you'd want the waterproofing. Some creosote is likely to leach out with each drop of water that contacts the treated wood, and that water is going into the ground below your tank.
It isn't worth giving yourself and everyone you want to feed off this land cancer to take a small piece of a large environmental issue and make it your own in that manner. Even making a platform out of solid creosoted 4x4s stacked twice as high as you need wouldn't make a dent in the larger issue.
I would put a gravel trench around the base of the water platform for proper drainage. I think that I would then make a form around the perimeter of where the platform will be. I would then either use traditional cement (not my first choice), or better yet, a portland-stabilised earth mixture, if your property has the right mix of sand and clay. An appropriately high rammed-earth platform won't fall apart, and it won't toxify the land you're seeking to steward.
