so i have to insulate the ground for my foundation of my passive solar addition im building...i want to use aircrete instead of blueboard foam because the addition is going around our well pump so it is in doors...and i dont need any foam leeching in our water...im pretty sure ive read about this on permies.com being an option but i just wanted to see what anyone thought on here...thnks

You can use foamed concrete for insulation, but I'd be sure you have a structural engineer check the design of any load bearing foundation. You'll be ok with enough surface area and strong enough beams to transfer and spread all the forces over the foamed concrete, but you need to design this.
