The Oklahoma Department of Environmental Quality (DEQ) has advised the Nash Water System, located in Grant County, to inform residents and users of the drinking water to use water that has been brought to a full, rolling boil for at least one minute, bottled water, or water from another acceptable source for consumption, use in food preparation, dishwashing and brushing teeth. This order was issued due to the presence of E. coli.

Consumers of the water system will be notified when the water is considered safe for human consumption. Federal law requires that consumers be notified when a public water supply exceeds certain maximum contaminant levels and might be harmful to the health of consumers.
