The Portland Water Bureau has returned to 100 percent Bull Run water supply. Due to a temporary shortage of ammonia at our Lusted Hill treatment facility, the Water Bureau had been blending the Bull Run supply with approximately 50 percent groundwater. This blend lasted for less than 24 hours. The activation of groundwater was not due to the Eagle Creek Fire.
It may take up to two weeks, depending on your location, for the change in source water to move through the distribution system. The Bull Run Watershed and the Columbia South Shore Well Field are both high quality water supplies which meet or surpass all federal and state drinking water regulations.
