Tualatin Water is Safe to Drink: Portland Boil Water Notice Ends

While Tualatin's water was not impacted by the recent "Boil Water Notice," please note that the "Boil Water Notice" has been lifted for Westside Tap Water customers who were affected.  Tualatin customers receive water from the Bull Run conduits, which were not impacted.  Residents and  businesses west of the Willamette River that have Portland water as a source may now drink tap water without boiling it first.  Follow-up testing of drinking water has shown the absence of bacterial contamination.  The Portland Water Bureau recommends flushing all taps for 2 minutes, or until the water runs cold before consuming it for the first time.  This will flush any potentially contaminated water from the plumbing.

The Portland Water Bureau issued a "Boil Water Notice" on Saturday, July 21, 2012, in response to a second positive test for bacterial contamination in Reservoir 3 in Washington Park.  Customers of the Portland Water Bureau west of the Willamette River were affected.  Customers of Burlington Water District, Valley View Water District, Palatine Hills Water District, City of Tigard, Lake Grove Water District, and West Slope Water District were also affected.

Portland Water Bureau and wholesale customers of Tualatin  Valley Water District, Southwood Water District and Raleigh Hills Water District were not affected. 

Upstream and downstream tests conducted since the notice was issued were clear of contamination.  As a precaution, the reservoir is being drained and will be inspected.  An investigation into determining the  source of contamination is ongoing.  The reservoir may be put back into service once it is determined to be safe to do so.
