NC DENR Dan River Preliminary Water Quality Test Results

The North Carolina Department of Environment and Natural Resources published test results from water quality testing on the Dan River. The following is an explanation about the tests they conducted:

“State test results completed Thursday for a number of water quality parameters, including 17 metals, show no violations of state water quality standards for most samples taken Monday and Tuesday near the site of the coal ash spill in Eden. Test results for the remaining parameters will be released as soon as they are available.

One metal, copper, was above the state action level surface water standard both Monday and Tuesday. Because copper is a naturally occurring element in North Carolina waters, action level exceedances are used to trigger further investigation. While levels of copper decreased significantly on Tuesday, DENR will continue to monitor copper and the other elements.

North Carolina has established its federally approved water quality standards based on scientific data designed to protect human health and the aquatic environment.

DENR is still waiting on metals analysis to be completed for boron, titanium, vanadium, iron, cobalt, beryllium, aluminum, selenium, lithium, manganese and strontium. A monitoring plan to characterize coal ash in the river bed and along the river banks is in development and will be implemented in the coming days.”
