You may notice slight color changes in your drinking water. Don’t panic! It’s normal - and harmless.
Heavy fall rains cause tannins (natural organic materials) to wash into streams that feed the Bull Run Watershed. Tannins do not change the quality of water, just the color.
The Bull Run provides some of the world’s best drinking water. Because it’s so high in quality, we do not need to heavily filter and treat our water – so the fall colors may show up in your faucet.
The Portland Water Bureau closely monitors our water systems. It ensures that it meets all state and federal quality and safety regulations – providing you with the best water possible.
