What about this baby turtle? Please help! ):?

Okay, this guy likes me & he went to the mexican mall & I said Ooo buy me something! :D & he actually did. Lol but he got me a baby turtle. It's in a little cage & he brought food for it. I want to put it in a bigger cage but I don't know if it's tap water or bottled water & should I wash my hands before touching it? It's light green with orange on its neck. Please help!
