If Uhura says that the water is safe to drink and to use then Thomas will drink some of the water and he will wash his face with it and he will continue following the group to whatever place they are going.
Nathan will use the water of the pool to refresh himself. He will look for a secluded spot and wash his bum, using soap from his grooming kit. If Uhura will report that the water is safe for drinking, he will drink some as well as replace the one in his canteen.
Lars attempts to convince the girls to come with him for a "Good time", and proceeds to follow his party members to the stream.
Thomas will just clean his bum a bit using his soap on a place that nobody cannot see him and he will wash his hands after. (Only if that is possible because Lars). He will then drink some of the water of the stream and he will put stream water in his canteen, then after he will come back to the group to see what is going on with Lars and the others.

Lars attempts to persuade the ladies to go somewhere private with him, like maybe some nearby bushes.
Out of Character: I really don't want to be inappropriate about this, but I'm trying to keep Lars in character.
Specific Action: Drink some water and immediately leave towards C3 so she does not get involved with whatever Lars is trying to start.
Specific Action: Nathan is not pleased by the lack of seriousness shown by Lars. He keeps looking at his companion with a severe expression, feeling anger mounting in his chest.
Out of Character: I failed my roll.
