Pink Water Scare in East Kennewick

Posted: Updated:

KENNEWICK, WA - We're hearing multiple reports of pink water in the residential water system in the eastern part of Kennewick. 

The city of Kennewick says a check valve at the water plant failed to close all the way, allowing more sodium permanganate in the system than normal. 

The city says this is not a harmful chemical. Instead, sodium permanganate is an oxidizing agent, which is regularly added to the city's drinking water. 

They city says workers are draining the clean well at the plant, and hope to have clear water restored within the next 24 hours. 

Again, the city says "pink water" people in eastern Kennewick may be experiencing, is not harmful. It simply has a temporary discoloration.
