Bodies of warm freshwater, such as lakes and rivers
Geothermal (naturally hot) water, such as hot springs
Warm water discharge from industrial plants
Geothermal (naturally hot) drinking water sources
Swimming pools that are poorly maintained, minimally-chlorinated, and/or un-chlorinated
Water heaters. Naegleria fowleri grows best at higher temperatures up to 115°F (46°C) and can survive for short periods at higher temperatures.
