Water Quality of Bull Run Compared to Groundwater 
As of Thursday June 11, the Portland Water Bureau is supplementing Bull Run water with approximately 8% groundwater from the Columbia South Shore Well Field.

Beginning Thursday, June 11, the Portland Water Bureau will begin using its groundwater wells in the Columbia South Shore Well Field to ensure adequate supplies of water to its customers while work on supply conduits from Bull Run is being completed. As part of system improvements, maintenance work is being conducted on the Water Bureau’s three supply conduits. Work to strengthen the interties between the conduits will soon begin on the last and largest conduit. This scheduled maintenance coincides with an increase in water demand. As a result, groundwater from the Columbia South Shore Well field will be used to continue supplying clean, safe and constant drinking water to customers. The groundwater system is estimated to contribute approximately 8% of supply for up to four weeks during the scheduled improvement work. While the work is being performed, the bureau will take the opportunity to perform its annual maintenance operation of the groundwater system, replacing the maintenance run scheduled for next month. Depending on location, it will take between one and eight days for groundwater to move through the distribution system and reach customers.
