At Nova, Jessica Morrison writes about this weird technique

I read that as “this one weird trick”. Use this one weird trick for your massive digging projects.

Kidding aside, it sounds pretty awesome.

They did use it for radioactive clean-up before… Back in the 90’s Oak Ridge National Lab used an ice wall to prevent contaminated water from spreading to a creek while it was cleaned up.

Still looking for the “weird” part. It’s just diaphragm walling. Other methods involve cement or epoxy. The nice thing about ice is you don’t create a permanent structure that might be in the way after it’s no longer needed.
