On Episode 3, Part 1, at the part where the wall blows up, turn on your Night Vision goggles and look to your left to find a message from Maggie.
Using an EPDD is very effective when an enemy is in the water. Just be careful not to be in the water when tasing someone. You will lose a little health but anything electronic like goggles and tasers except for the flashlight will be disabled for a short while.
