The Iowa Department of Natural Resources (DNR) is investigating a red color in Little Beaver Creek after the Grimes wastewater treatment plant announced the red color entering the system Friday afternoon. Operators from the city’s treatment plant and DNR staff worked to trace the color to an area in Grimes but were unable to identify the chemical or the source. No dead fish or environmental effects have been noted. The DNR will consider appropriate enforcement action with the city and the responsible party for violation of a water quality standard.
