mold behind drywall near plumbing 11

There was a musty smell in the laundry room for weeks, but I couldn't figure out where it was coming from. Finally, I noticed a small water stain near the base of the wall, and when I peeled back the drywall, I found black mold creeping along the backside, right where the pipe had been slowly leaking. It's a hidden mess that only shows itself when you start digging.
