Swimming pools require mass amounts of chemicals and treatment to ensure it’s safe for swimming, but why not natural bodies of water? Given the amount of waste and bacteria, coupled with water creeping into the ears, nose, etc., why don’t we see more cases of infection?

you can get sick from lake and river water. usually it’s not the case tho. the bacteria in natural bodies of water isn’t usually very strong and your immune system can kill it quite easily.
chlorine in pool water is there to stop alge from forming in the still water and to kill bacteria that you shed off your body when you swim.
