Hi Jules and welcome to Pond Boss. Many of us swim in our ponds and have no problems with it what so ever. If you are really concerned about water quality you can have it tested. If you have fish in the pond there are some species that can nip at you but they don't have teeth so it is more startling than anything.

Hang on for more answers and thanks for joining in and posting.
