FINAL FLOW STUDY OF ROCKY RIVER PLANNED FOR OCTOBER 31
County Residents May Notice Non-Toxic Red Tint in the River
Concord, NC- On Monday, October 31, Tetra Tech, an environmental contractor for the Water and Sewer Authority of Cabarrus County, will measure flow speed of Rocky River by placing in-stream automatic data loggers and a non-toxic red dye at four locations along the entire Rocky River mainstream.
This measurement is a necessary component of the Authority’s new strategic master plan and will provide data to make informed decisions for the future. It was requested by and approved by the North Carolina Department of Environmental Quality.
Dye placement is planned for Monday, but may be delayed with any significant weekend rainfall. Residents may notice the red tint to the river for few days following the placement of the dye. This scientific study is harmless and there is no cause for concern.
“The red-colored dye used in the Rocky River is different than food dyes. It is formulated as a water tracer and has been used for decades and is approved by the EPA as harmless to people, fish, and plants when diluted at scientifically calculated concentrations, which were employed in this study,” said Hillary Yonce, Professional Hydrologist and Environmental Scientist with Tetra Tech.
