Join us for Cycle the Well Field on June 1st

By Lindsay Wochnick 0 Comments

What local resource is capable of producing close to 100 million gallons per day of high quality drinking water, is the second largest water source in the State of Oregon and is used as a back up water supply for customers served by the Portland Water Bureau? 

Answer: The Columbia South Shore Well Field!

Columbia South Shore Well Field Groundwater Aquifers

The Columbia South Shore Well Field is a series of 27 water supply wells located between the Columbia River and I-84, and stretching from I-205 in Portland all the way to Troutdale. Groundwater from the well field is used to supplement water from the Bull Run watershed during turbidity events or hot summer weather when water demand is greatest.
