Water Quality of Bull Run Compared to Groundwater 

The Portland Water Bureau is delivering 100% Bull Run Water

On July 9, 2014, the Portland Water Bureau returned to 100 percent Bull Run water after completing its maintenance operation that blended a small portion of water from its Columbia South Shore Well Field into the water distribution system. On June 30, the Portland Water Bureau detected a leak on one of the supply conduits from the Bull Run. The conduit was taken out of service to repair the leak, requiring the Portland Water Bureau to augment the Bull Run supply with drinking water from the Columbia South Shore Well Field. While using groundwater, the bureau took the opportunity to perform its annual maintenance operation of the groundwater system from July 7 to July 9. This replaces the maintenance run scheduled for August 2014.
