Sand, for sure.

It's quite dependent on the density (amount of tonnes per cubic metre) of the substance. Water has a density, at 21 degrees C, of 1 tonne per cubic metre...everything is related back to that fact.

Density is also realted to how many air spaces are between the particles of the substance - like if it's really dense there aren't many air pockets, therefore the water will have a hard time flowing, even through sand. If you were talking about iron particles in a loose agglomeration, then water would be able to flow through...

But if it was "in situ" (naturally occurring rather than just in a loose pile), then the particle sizes play a big role. They are, in order, sand; loam (mixture of sand, clay and topsoil); clay (the smallest particles of soil - less than 2 microns which is less than 2/1000ths of a millimetre) then iron.

If the iron is in situ - i.e magnetite ore - water would still be able to percolate through it - it would simply take a very long time. There's nothing really totally impermeable to H2O as it's normally a tiny molecule - smaller than just about anything else.

Hope this helps!

1. Sand.

Water will flow through sand easialy
In order: Sand, Loam, Clay
Iron(NO WATER WILL FLOW THROUGH IRON)

assuming that your iron is solid,water will flow most easily through sand.
you can try it for yourself.

I think loam. It's more permeable( and sorta' spongy.).
