The Joint Powers Water Board says pink water coming from faucets in several Wright County homes is safe to drink, according to a news release issued Tuesday.
According to the utility, the bright pink to purple water is caused by a non-toxic concentration of potassium permanganate. The chemical is used in many water treatment plants to control taste and odors, and also prevents rusty water.
Water customers in St. Michael, Albertville and Hanover are affected.
A similar incident occurred in May, FOX9 says, after more than 100 gallons of the pink chemical flowed into the water supply.
The utility told FOX9 that wells were shut down for maintenance, but the chemical feed kept running solution into the lines. Residents are again experiencing the same thing.
Plant piping modifications are in the works to prevent this from happening in the future.
