Officials in the Western Kansas town of Satanta have a warning after high levels of nitrates were discovered in the water.
Nitrates can be harmful to infants younger than six months. The water could make the seriously ill, or if untreated, it could be deadly.
The city sent a letter warning people not to use the water to make baby formula and that boiling the water won’t help.
The city says it’s increasing testing until the water is back to acceptable levels.
