The Oklahoma Department of Environmental Quality (DEQ) has required Tonkawa PWS, located in Kay County, to inform users of its 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 E. coli in the drinking water.
The following water system purchases water from Tonkawa PWS, and is therefore also under the mandatory boil order:
- Tonkawa Tribe of Indians of Oklahoma
Users 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.
