Bloomington residents might notice their tap water has a pink tint Sunday, but don't worry, the city says it's harmless.

A pump controlling the feed of a treatment called Sodium Permanganate malfunctioned 2 p.m. Saturday, according to a press release from the City of Bloomington. The problem has reportedly been fixed. If the water has a noticeable color change, residents are asked to call 812-339-1444.

The pink-tinted water doesn't pose a health risk and shouldn’t taste different, but it is recommended to wait to do laundry until the water is clear again. The water will also not affect plumbing, according to the release.

The City of Bloomington Utilities said it will take several days for this water to move through the system but should not last at any one home for more than several hours to one day, according to the release.

Sodium Permanganate, which is giving the water the pink color, is used primarily to control taste and odors, control biological growth and remove iron and manganese.
