Portland Drinking Water Overview
Population: ~650,000 | Source: Bull Run Watershed and Columbia South Shore Well Field
Portland's Bull Run Watershed, a protected old-growth forest on Mount Hood, provides some of the cleanest source water of any major US city. The water is so clean that Portland has operated under a treatment variance, though a new filtration plant is being built. Lead from older home plumbing, not from the source water, is the primary concern.
