Chlorine shock for water with amoeba that killed rafter

CHARLOTTE, N.C. (AP) — Officials plan to treat water at a North Carolina whitewater recreation center with 10 times the chlorine typically needed to kill a brain-eating amoeba that caused the death of a rafter from Ohio last month.

Mecklenburg County health officials said Wednesday that they have told the U.S. National Whitewater Center in Charlotte that it can begin treating the water whenever it is ready.

The center has drained the water from its rapids into a downstream pond to be treated. The center is also digging up the sediment at the bottom of the waterway where the amoeba lives and will spread it in nearby fields to be killed by exposure to sunlight.

Health officials say they will carefully monitor the water before it flows back into the Catawba River.
