Notice a Slight Change In Your Water? Here's Why It May Smell Different

Posted Thursday, May 5, 2022

Skagit PUD is opening three intertie connections with the city of Anacortes to supplement our water system for a few days while crews perform work on the Judy Reservoir to Mount Vernon Transmission Pipeline Project.

Some customers may notice a slight chlorine smell in their water during this time. The smell is due to Anacortes’ disinfection process that uses “free” chlorine, which interacts with water from Skagit PUD’s Judy Reservoir System.

Free chlorine refers to both hypochlorous acid (HOCl) and the hypochlorite (OCl-) ion or bleach and is commonly added to water systems for disinfection. The mixing of different water chemistries can create a more intense chlorine odor.

Nevertheless, the water is perfectly safe to drink and meets or exceeds Federal and State standards for drinking water. 

Bayview, the Skagit Golf and Country Club area, Burlington, Mount Vernon, and West Mount Vernon will be the most affected areas.

The chlorine smell will dissipate by May 11, once the work is completed and the interties are turned off.
