People in Stephenville are being advised against using town water after high levels of manganese were detected.
The mineral is safe to consume, except for infants under the age of one.
The town asks parents to refrain from using the water to mix with any powder-based formulas as the mineral cannot be removed, even through vigorous boiling.
The water is safe for consumption by anyone over the age of one, and is safe for all other uses such as washing dishes, bathing, and laundry.
