January 16th due to recent heavy rains, producing turbidity levels that exceeded federal regulations for drinking water. High turbidity events produce suspended solids in the drinking water.
According to Water Bureau Administrator David
Shaff, approximately 1.3 billion gallons of groundwater was used during the period January 16th through February 1, 2011. It will take
about 24 to 60 hours for Bull Run water to move through the distribution system and replace the groundwater.
Because the Bull Run water supply is unfiltered,
the Portland Water Bureau established the
Columbia South Shore Well Field. This backup groundwater system enables the Water Bureau to continue serving customers when the unfiltered
Bull Run system is unavailable during intense storm events.
“Portland is extremely fortunate to have two very high quality sources of drinking water,” says Shaff. “Having a back-up during storm events was an important reason the City developed the groundwater source. Without the well field we would be required to build a treatment plant and filter the Bull Run source. Few utilities have this flexibility.”
The well field became operational in 1985. It’s the second largest source of drinking water in Oregon, just after the Bull Run. The Portland Water Bureau has a strong resource protection program to regulate activities in the well head area to protect this invaluable resource.

Tell me about a challenging project that you have been involved with at the Water Bureau. Water main replacements in the SW Hills are usually tough. I am often amazed that we are somehow able to install pipelines in that cramped, steep geography while avoiding all the other utilities, landslides, erosion, environmentally sensitive areas and homeowners who extend their extraordinarily well-tended gardens and rock walls over existing mains.

Color in the water can result from many sources. As we reactivate the Bull Run supply, color is most probably from decaying vegetation or soil brought into the system during our last storm. Organic matter that causes color is also referred to as humic matter and it could be the result of peat materials, plankton, and/or aquatic weeds. Color does not directly influence turbidity, which is a measurement of the amount of light reflected by suspended particles. Turbidity is measured in nephelometric turbidity unit (NTUs) by a turbidimeter. Color changes are normal for this time of year. While the color itself is not objectionable from the standpoint of health, its presence can be aesthetically objectionable to some people.
There are other sources of color which could occur in isolated situations, throughout our system. For example, the water could be colored because of an isolated pipe break, flushing operations, or something wrong with the customer's private plumbing. Color can also be the result of iron, manganese, or copper in the water, however this has typically not been a problem for our system.
The Environmental Protection Agency considers color a secondary/aesthetic contaminant. The secondary, non-enforceable maximum contaminant level, known as an SMCL, is 15 color units. When color is measured, a stock color standard, with a color unit of 500 is diluted to make various tubes, with known color values. The standard, known color values are compared to the sample and a color value is determined. Color can also be measured with a spectrophotometer, which is the method used by the Portland Water Bureau (Standard Method for Water and Wastewater, 19th Ed. 2120C).
