Tap water runs pink in Canada.

Neon pink water began flowing out of the taps in a small Canadian town earlier this week, startling residents.

The odd hue that surfaced in Onoway, Alberta, was likely caused by an automation or valve problem at the local water treatment plant, the mayor's office said.

Because of that issue, potassium permanganate, a chemical used in water treatment, got into the public distribution lines, Onoway's Mayor Dale Krasnow said in a pair of statements.
