Water and blood filled the Meta's lungs due to the puncture wounds that were caused by Tucker. There were four puncture wounds, two in the front and two in the back, as the sword went all the way through. It's entirely possible Meta would have drowned by his own blood even if he hadn't fallen in the water.
