I think it is very dependent on the body of water. At my health club, where I exercise 3 or 4 times a week in the pool, they test the water hourly in the pool and in the hot tubs.
I think some lakes may not be a clean as others. We have a very rustic cabin on a lake in Maine. The water is rated to be pure enough to be used as drinking water!
I have no idea about the ocean. Again, I think it would depend on whether the area of the ocean is in a cove or somewhere that might not have the exchange of water as frequently, or might get runoff from the shore.
I am very careful though, being on immunosuppressants, and although I know they test the hot tubs I very rarely go in, just in case something may have fouled the water after the last testing. I would really like to because many of the people in the aerobics class do use it so it's sort of a social thing, but I forego it and use the sauna after my shower instead.
You really should check with your transplant department though, they know best I think.

@gaylea1, I am going to make a nonmedical guess that when your bile duct issues are resolved, your taste will return to normal. I have my fingers crossed🤞.

As far as swimming etc, here is what I found in a handout after my transplant about Infection Prevention after Transplant. It is a typed page, and there is no quoted source. Here is what it says about water:
-Avoid use of hot tubs, especially public ones. Swimming in pools or the ocean is okay as long a you do not have any open cuts or sores. Do not swallow the water. Wear water shoes or sandals when walking along the beach or wading into water from the shore.
-Do not wade into flood waters or murky lakes and streams.

I am happy that @contentandwell has provided excellent information from her own experience of what works for her. I am not a water person.

I wonder if anyone else has any water related experience to share? What have you been told? What works for you?
