Corrupted Water is a green-purple-ish kind of water which damages you if you touch it. It does two damage (1 heart) per second if you are touching it. To make it, let Ender Acid touch normal water. Every mob gets damaged by this water except for The Enderdragon and The Wither and all other modded bosses that have something to do with Wither or Ender power. This also randomly generates in The End.
