Paranoid and carefree summer swimmers, take notice.
At least 17 percent of those smiling, splashing people admit to peeing in a pool, and 78 percent of people suspect their fellow swimmers are urinating in the water, according to a new study by the Water Quality and Health Council.
But that suspicious patch of warm water might not be the worst of what lurks in the pool, or the worst of possible unhygienic threats in summer fun.
Infectious disease experts, bacteriologists and parasitologists say some of what seems germy and gross is probably safe, while other summer fun has hidden dangers.
As you're suiting, slathering and gearing up to go outside, it might be worth a look at the top unhygienic summer concerns.
Although peeing in the pool was the most popular admonition, there are other poolside confessions that could cause more illness, according to the Water Quality and Health Council, which is sponsored by the Chlorine Chemistry Division of the American Chemistry Council.
