I got very s* last summer and I think it possibly had to do with swimming in a public pool but I still swim in them. I don't have one myself and I love to swim so I'm not willing to give that up. Lol my boyfriend and a friend and I almost got arrested once for sneaking into a gated community and swimming in their pool. When they didn't find any drugs or alcohol on us they let us go though. Uh..anyway....

As long as you don't accidentally swallow any water it should be fine. Also I wouldn't swim in it if it was that nasty luke-warm temperature. I feel like that is just a breeding ground for bacteria.
