TOLEDO, Ohio -- Toledo Mayor Michael Collins announced early Monday that tests show some toxins remain in the city's drinking water.
That means the water ban will continue for 400,000 city residents.
Ohio Governor John Kasich said Sunday that officials would wait for the results of the tests before clearing water as safe to use for the more than 400,000 people affected.
Residents are being asked not to drink the water or brush their teeth.
Kasich spoke to reporters in Toledo Sunday afternoon on the matter.
Earlier in the day, Collins tweeted that testing results on the water were delayed, and gathering samples took longer than expected.
Kasich Sunday afternoon said authorities are making sure to take their time to make sure the water is safe, and don't want to rush the process.
"Sometimes people would like to move quickly, but the way I look at it and the way the mayor and I have discussed it, I want to make sure that I would be comfortable with my family, with my daughters and my wife, drinking the water and when I'm comfortable with that, then I think we're in a position where where we can say to the people here in Toledo that we feel good about it."
He tweeted that officials are committed to fixing the crisis.
Met today w/leaders in Toledo. We're committed to fixing the immediate crisis & addressing the long-term challenges. #emptyglasscity

Toledo officials issued the water warning early Saturday after tests revealed the presence of a toxin possibly from algae on Lake Erie.
Ohio's EPA is trying to figure out what caused a sudden spike in the toxins.
Late Saturday, Kasich ordered the state's National Guard to deliver pallets of bottled water, water purification systems and meals ready to eat to residents in Lucas, Wood and Fulton counties.
The city of Cleveland sent a water buggy carrying 400 gallons of water to Toledo Saturday night.
