About Portland
Portland, Oregon, known as the "City of Roses," is situated in the Pacific Northwest region of the United States. It is renowned for its parks, bridges, and bicycle paths, as well as its eco-friendly and liberal politics.
Water Situation
Portland's tap water primarily comes from the Bull Run Watershed, a surface water source known for its purity and low contamination levels. The water is considered high quality, and the city has opted out of filtration processes demanded by other regions, relying instead on intensive monitoring. Historically, Portland water has been soft with a low mineral content, and this has remained consistent over time.
