CHARLESTON, W.Va. (WSAZ) -- WSAZ is learning new details about how the water is being tested after a chemical spilled into the Elk River last month.
Army National Guard First Sgt. Brian Burns was taking samples at J.E. Robins Elementary Thursday in Kanawha County, after reports of a licorice odor.
Sgt. Burns says they take three samples of the water.
Two samples are sent to two different labs, so there is confirmation and validation. "Two separate labs come back with their own individual results. We compare them to make sure sure are under the non-detect stand," Sgt. Burns said.
The third sample is held by the National Guard so if in the future there is any discrepancy about detectable levels at the site, they will have a sample to show proof.
