No. Neither the groundwater nor Bull Run source water is filtered. The Bull Run source meets the filtration avoidance criteria of the Surface Water Treatment Rule. The State of Oregon approved Portland's compliance with these criteria in 1992. Portland continues to meet these criteria on an ongoing basis.
No. The Portland Water Bureau does not add fluoride to the water. Fluoride is a naturally occurring trace element in surface and groundwater. The U.S. Public Health Service and the Centers for Disease Control and Prevention consider the fluoride levels in Portland’s water sources to be lower than optimal for the prevention of tooth decay. You may want to consult with your dentist about fluoride treatment to help prevent tooth decay, especially for young children.
Portland’s water is very soft. The hardness of Bull Run water is typically 3-8 parts per million (ppm), or approximately ¼ to ½ a grain of hardness per gallon. For short periods of time Portland may supplement the Bull Run supply with groundwater. Portland’s groundwater hardness is approximately 80 ppm (about 5 grains per gallon), which is considered moderately hard.
The pH of Portland’s drinking water typically ranges between 7.4 and 8.1.
There is currently no drinking water standard for sodium. Sodium is an essential nutrient. Sodium in Portland's water typically ranges between 2 and 9 ppm, a level unlikely to contribute to adverse health effects.
Radon is a naturally occurring radioactive gas that cannot be seen, tasted or smelled. Radon has never been detected in the Bull Run surface water supply. In past years, radon has been detected at varying levels in Portland’s groundwater wells. Based on the historical levels and limited amount of groundwater used, radon is unlikely to contribute to adverse health effects. For more information about radon, call the EPA’s Radon Hotline 800-SOS-RADON or www.epa.gov/radon/rnwater.html.
