@christielynn Figure 1 of the paper is misleading regarding locations proximity to different types of water bodies. The text does talk about salinity (p. 329, 2nd column, 2nd last paragraph): “Previous studies have found that NTM do not grow well in waters of high salinity, as in ocean water. (37) Optimal salinity for NTM is 1–2% salinity, while ocean water is typically 3–4%. (37) While ocean water is quite prevalent around the state of Florida, only two patients in the cohort lived closer to an ocean than any other water type. One of these two patients cultured positive for NTM; however, she also lived within 500 meters of a body of water in the rivers/streams category.”
