The cause was a hole in the cast iron P-trap. The P-trap is a standard plumbing fixture. It traps solid material in the waste water that can clog the pipes deeper within system. It also stops gases from seeping back into the house.
In this case, we cut open the wall and removed a section of old pipe. We replaced it with newer pipe. We sealed up the wall, cleaned up the floor, and moved the washing machine back into place. Problem solved.
