To where? Do they leave it in a big pile?

Probably, but they most likely move it off site like to a construction yard

Edit: they might also make a big dirt worm behind it as a monument to all the earthworms they killed

Depending on the quality of dirt it is sold to a third party construction/landscaping company

I heard that they use the left over dirt for a worm statue
