 How much pee is in a water park wave pool? Well, if there's 20 gallons in the average public pool, the answer is a lot. And that pee is not alone. Every year, there are water park-related outbreaks for bacteria and chlorine-resistant parasites, not to mention all the bizarre and terrifying injuries. But if you're going anyway, here are some ways to limit your risk. Sandals, water shoes, whatever. There should always be something on your feet. Those height and weight limits are not just suggestions. And any signs about the position you should be in are there for a reason. Check the CDC's website for local outbreaks before planning your trip.
