This is why if you get an acid burn on your skin, emergency protocol is to rinse with cold water. Same thing for getting chemicals in your eye you're told to wash you eye.
"poisonous water" usually doesn't contain actual poison. most of the time it contains microorganisms that produce poison once they're inside of the human body.
