well you can never go wrong with halucinations (sp) like a guy looking in the mirror and seeing something happen to his face in the mirror that isnt happening. Also maybe tooth decay from grinding teeth or just whatevers in the water. Visions of dead people is good and fucked up nightmares. Pretty much making the character have a really bad trip lol.

Algae or kelp. They're becoming part of the ecosystem as it becomes a part of them.

Didnt they do a movie like that?

Any flesh that touches the water begins to rot/decay. The rot spreads slowly throughout the body, thus the limb chopping.

Sounds alot like leperacy (sp). If this is supposed to be a supernatural thriller then you want the change to be more mental than physical. A good example is the most recent Amityville Horror. Ryan Reynolds did a great job showing mental change just through body language. Then there were the physical changes like him vomitting and his hands become rough from working on the house so muchThe lack of sleep. etc. Try using some of the symptoms of cabin fever. Not the movie but the mental instibility. This involves excessive sleep, paranoia(sp), unnessisary laughter, and sometime halusinations.

They could be hallucinating that their skin is rotting and cut off limbs out of delusion. ???

have you ever seen honeycomb tripe? It is an incredible-looking bit of calf's stomach

The exposed skin could take on an appearance like this...halfway between pruning and actual decay - it could be quite unnerving

The water could turn them into Zombie Ninjas! XD
J/p.

The water could turn each person into a different type of monster/creature/animal everytime.

keep the water but make it dark like black water.(black lake)the contact with the water make them crazy/evil. the water is like a malignant shadow.it unleashes the blackness of the persons soul.exmaple child setting a parent on fire. husband hog ties his family and put them in the trunk of the car.
its just an idea.

I think the black water would be much. Something like that would make me as a veiwer go "No lets not worry about the water being black. It couldnt hurt us." sarcasm like ya know? You have to get into the veiwer's head. Make it look like ordinary water so people will be paranoid about their water after watching it lol.
