CHARLOTTE, NC (WJZY) - Officials say the chlorine treatment at the U.S. National Whitewater Center worked and are now working on dechlorinating the water.
Chlorine treatment at @usnwc worked. They are now working on dechlorination now and hope to start moving the water into river.— Yolian Ortiz FOX46 (@YolianFOX46) July 29, 2016
Thursday afternoon, The Whitewater Center started the treatment process Mecklenburg Health Officials laid out. That includes chlorinating the water and sediment that collected at the lower pool to kill the "Brain Eating" amoeba.
"The goal is to have that high concentration for at least two hours and really let it soak," Catawba Riverkeeper Sam Perkins said.
The problem, health officials couldn't keep the chlorine levels where they wanted for those two hours.
"It did provide treatment and kill the amoeba, it just wasn't up to the standard that was in the plan," Perkins said.
The Catawba Riverkeeper tells FOX 46 Charlotte the process is planned to start again Friday before sunrise, when there's cooler temperatures
"If it even cools down into the 80s or hopefully the 70s at night that will go a long way in helping that water hold that chlorine so it doesn't evaporate out."
After they reach the two hour mark with proper chlorine levels...they will take the chlorine out...so only pure water enters the river.
"So we're confident that we're protecting public health and the environment will not be impacted," Environmental program manager for Mecklenburg County Lisa Corbitt said.
But it won't go straight into the river right away.
"It actually be traveling over the surface of the ground thru check dams to slow it down a little bit and through highly vegetated material for about two football lengths," Corbitt said.
This extra step, will serve as a natural treatment where the water can be absorbed into the soil, stopping some from completely entering the river.
