Residents of Norman can breathe easy—at least in terms of physical health—after officials from the Department of Environmental Quality confirmed that a recent fish kill poses no immediate threat to the public. The Department of Environmental Quality, in collaboration with City staff, responded to concerns on Tuesday, following the discovery of dead fish in Rock Creek, as reported by the City of Norman.
During their inspection between 60th Avenue NE and 48th Avenue NE, approximately 40 fish, ranging in size from 2 to 5 inches, were found. According to the City of Norman, the likely cause is linked to a water flushing procedure from the Vernon Campbell Water Treatment Plant. Recent repairs to a chlorination unit led to lower than usual chlorine levels in the drinking water, prompting the need for system flushing.
Norman's City staff adhered to the proper flushing protocols, including the use of de-chlorination tablets that align with current standards. Unfortunately, chlorine, even in small amounts, can be detrimental to aquatic life. The City of Norman's routine maintenance of fire hydrants and water lines includes such flushing processes, but it seems possible de-chlorination efforts at the time were not quite up to snuff for our finned friends.
No penalties were given out from the Department of Environmental Quality visit, but Norman authorities are not dismissing the incident lightly. More extensive surveys of the creek are underway, and the de-chlorination methods are under a microscope to prevent future harm to wildlife. As the City of Norman and Department of Environmental Quality work together to safeguard both human and animal residents, anyone with concerns about their drinking water is encouraged to contact the Vernon Campbell Water Treatment Plant at 405-321-2182 for more information.
