Portland boil-water alert: Live updates (http://www.oregonlive.com/portland/index.ssf/2014/05/portland_boil_water_alert_live.html).
The Portland Water Bureau issued a city-wide boil notice on Friday morning after water staffers detected E. coli in three separate tests during the past three days.
The Oregon Health Authority required the city-wide notice, which also applies to Portland's whole-sale customers that also receive water from the Bull Run Watershed.
Routine inspections at two of the city's Mt. Tabor reservoirs produced the three positive E. coli tests. City employees performed the tests, according to Jaymee Cuti, bureau spokesperson.
The boil notice applies to 670,000 customers, according to Cuti. Portland supplies drinking water to 935,000 customers in the metro region.
City officials are hosting an emergency press conference at noon.
"While we believe at this time that the potential health risk is relatively small, we take any contamination seriously and are taking every precaution to protect public health," said Portland Water Bureau Administrator David Shaff in the release.
The Oregonian will be there and this story will continue to be updated.
Cuti said the boil notice will be in effect until the city produces "a clean sample." Cuti said she has no idea when that might be.
Here's the full release from the city:
The State of Oregon Health Authority's Drinking Water Program has required the City of Portland to issue a Boil Water Notice for all Portland Water Bureau customers and some regional water providers.
Until further notice, all Portland Water Bureau customers and those in the affected areas should boil all tap water used for drinking, food preparation, tooth brushing and ice for at least one minute. Ice or any beverages prepared with un-boiled tap water on or after May 20 should be discarded. Detailed maps, fact sheets and additional information can be found on the Water Bureau's website at www.portlandoregon.gov/water/boilwaternotice (https://www.portlandoregon.gov/water/boilwaternotice) or by calling Customer Service at 503-823-7770.
In three separate incidents from May 20 to May 23, repeat water samples confirmed the presence of total coliform and E. coli in routine drinking water samples. The water samples that tested positive for bacteria were collected at the outlets of Mt. Tabor Reservoirs 1 and 5, and at the SE 2nd Avenue and Salmon Street water sampling station. Both reservoirs have been taken offline.
A press conference will be held at noon today at the City of Portland Emergency Coordination Center, 9911 SE Bush Street in Portland.
All Portland Water Bureau customers are affected. Also affected are customers of the following water providers:
Burlington Water District
City of Gresham (North of I-84)
Lake Grove Water District
Lorna Portland Water
Palatine Hill Water District
Rockwood Water District
Tigard Water Service Area (including Durham, King City and Bull Mountain)
Valley View Water District
West Slope Water District
"While we believe at this time that the potential health risk is relatively small, we take any contamination seriously and are taking every precaution to protect public health," said Portland Water Bureau Administrator David Shaff.
Consuming boiled and bottled water will ensure public health protection until the Water Bureau can determine that the water system is clean of contamination through surveillance sampling. Customers will be notified when they no longer have to boil their water. The Portland Water Bureau is working with the Multnomah County Health Department to provide health-related information to the public.
"The chance of any health problems related to this water test result is low. If any problems occur, we would expect diarrhea," said Dr. Paul Lewis, Interim Tri-County Health Officer. "We monitor cases of bacterial diarrhea and will be aware of any increase following this event."
The Portland Water Bureau collects approximately 240 routine bacterial samples per month throughout the system. The test to determine the presence of bacteria takes about 18 hours. It is not unusual for one of these samples to test positive for bacteria. Samples to confirm possible contamination are collected immediately after an initial detection of the presence of bacteria in drinking water. Once the detection has been confirmed, public health officials recommend that the public boil all tap water before consuming.
Contamination can occur when there is a loss of water pressure, a pipe breaks, or conditions that expose drinking water to outside elements. The Portland Water Bureau is performing a full investigation to identify the cause of the contamination. However, it is not always possible to make an exact determination.
Customers can visit www.portlandoregon.gov/water/boilwaternotice (https://www.portlandoregon.gov/water/boilwaternotice)to determine if their home or business is in the Boil Water Notice area. The Boil Water Notice, fact sheets and contact information are provided on this same website. For more information, affected customers should contact the Portland Water Bureau Customer Service at 503-823-7770.
