Rafting activities closed at Whitewater Center after deadly amoeba found | WSOC-TVLocal, state and federal health officials are investigating after an Ohio teenager died from a brain-eating amoeba days after visiting the Whitewater Center in Charlotte.
The US National Whitewater Center sources its water from the Charlotte Mecklenburg Utilities Department and two wells located on the premises. The water contained in the whitewater channels is in a closed loop system comprised entirely of concrete. The water is disinfected with ultraviolet radiation and filtered with a disc filtration system. The UV system is a constant application and treats 12 million gallons of water every 24 hours which is the total volume of the system. In addition to the UV treatment, the Center periodically augments that treatment through the injection of chlorine into the system.
The levels of UV radiation disinfection utilized every day, continuously, at the Center are sufficient to “inactivate” the water born amoeba in question to an effective level of 99.99%"
