The Poison Release: Water Pollution Technique is a C-ranked Ninjutsu technique that can only be used by members of the Gekidoku Clan. After the user preforms the required handseals he/she will then place their hands the surface of a water body. Afterwards, the water is rendered polluted and unsuitable for human use through a somewhat long process (At least one post, and even more for large water bodies). The user can also instead contaminate the water with his/her poison of choice
