*Estimates are rounded to 3 significant figures. CrI, credible interval; NRND, nonrecreational nondrinking; NTM, nontuberculous mycobacteria; STEC, Shiga toxin–producing Escherichia coli.†Recreational water is used for recreational activities (e.g., swimming) in treated (e.g., pools, hot tubs, and splash pads) or untreated (e.g., lakes, rivers, and oceans) venues (19). ‡Drinking water is used primarily for drinking but can also be used for hygiene activities, like washing or showering, and can come from a public water system, a private well, or commercially bottled sources (19). §NRND water is used for purposes other than recreation or drinking (e.g., for agriculture, industry, medical treatment, backcountry streams, or flood waters) (19).
