    27,219: That’s how many illnesses related to “recreational water” were reported between 2000 and 2014, according to a study by the Centers for Disease Control and Prevention. “Recreational water” is governmentese for “swimming pool water” — filthy, disease-ridden pool water, it turns out. About a third of the reported illnesses came from hotel pools, a third from public parks or clubs, and 10 percent from water parks. The CDC’s sage advice: Never drink pool water.
