Why did Canadian town's water turn hot pink?

water turns pink in Canadian town

Residents of a small Canadian town woke up to quite a colorful surprise earlier this week: Hot pink tap water.

Complaints and concerns about the water’s odd hue started pouring into the town’s office on Monday, prompting officials from Onoway, Alberta, to investigate.

“This is what just happened in the Town of Onoway,” one local resident posted on Facebook Tuesday afternoon, sharing several photos of the neon pink-colored water in her house. “This is a disaster.”

“Pink water in Onoway, Alberta -- complete health hazard,” a Canadian Facebook group wrote. “Don’t drink the water.”

Onoway’s Mayor Dale Krasnow issued an apology to the town’s 1,000 residents on Monday, and said he would work to assess what exactly happened that led to the strange color.

Krasnow said it appears that a valve may have gotten stuck, allowing potassium permanganate -- a common chemical used for water treatment -- to get into the sump reservoir and thereby into the town’s water distribution system. Potassium permanganate is used to remove iron and manganese from well water. When dissolved in water, it causes a slightly pink tint.

“Once we realized this substance had gotten beyond our reservoir and into our distribution lines Pubic Works immediately commenced flushing of all our distribution lines throughout the Town,” Krasnow said in an online statement. “Unfortunately our distribution system is a loop system which makes it much more difficult to control and isolate the water flow.”

Alberta Environment and Parks (AEP) issued a public advisory to alert residents to the matter, but Krasnow said “all indications are that there was never a public health risk.”

Health officials recommended residents run their taps until the water is clear before using.

On Tuesday, social media users continued to post photos and videos of their pink water.
