The city of Portland's main water source is the "Bull Run Watershed" and the "Colombia South Shore Well Field", as well as groundwater sources and creeks/springs. I did some research and found out Oregon is one of the top 10 cleanest tap water sources in the states-- due to low levels of impurities!! Surprisingly, we don't source any of our drinking water from Mt.Hood although it seems relatively close.
