MEDIA RELEASE 09/24/2018: Bull Run Drinking Water Supply Not Treated for Cryptosporidium

While small amounts of Cryptosporidium were detected coming from the Bull Run source starting in 2017, Cryptosporidium has not been detected in Portland’s drinking water since April 10, 2018. Over the next nine years, the Portland Water Bureau will be installing a new treatment plant to remove Cryptosporidium from Bull Run drinking water.

Until the filtration plant is online, the Portland Water Bureau is also committed to continued monitoring of the Bull Run and a range of actions to maintain public health protections. This includes informing the public of the potential risks of Cryptosporidium in drinking water and Portland’s plan for filtration by sharing the following information with the public on a quarterly basis.  

The Portland Water Bureau does not currently treat for Cryptosporidium but is required to do so under the drinking water regulations. Portland is working to install filtration by 2027 under a compliance schedule with the Oregon Health Authority. In the meantime, Portland Water Bureau is implementing interim measures such as watershed protection and additional monitoring to protect public health. Consultation with public health officials has concluded that at this time, customers do not need to take any additional precautions.

Exposure to Cryptosporidium can cause cryptosporidiosis, a serious illness. Symptoms can include diarrhea, vomiting, fever, and stomach pain. People with healthy immune systems recover without medical treatment. According to the Center for Disease Control and Prevention (CDC), people with severely weakened immune systems are at risk for more serious disease. Symptoms may be more severe and could lead to serious life-threatening illness. Examples of people with weakened immune systems include those with AIDS, those with inherited diseases that affect the immune system, and cancer and transplant patients who are taking certain immunosuppressive drugs.

The Environmental Protection Agency has estimated that a small percentage of the population could experience gastrointestinal illness from Cryptosporidium and advises that customers who are immunocompromised and receive their drinking water from the Bull Run Watershed consult with their health care professional about the safety of drinking the tap water. The Portland Water Bureau and Burlington, City of Gresham, City of Sandy, City of Tualatin, Green Valley, GNR, Hideaway Hills, Lake Grove, Lorna Portland Water, Lusted, Palatine Hill, Pleasant Home, Raleigh, Rockwood, Skyview Acres, Tualatin Valley, Two Rivers, Valley View and West Slope Water Districts receive all or part of their drinking water supply from the Bull Run. To learn if your drinking water comes from Bull Run, please contact your local water provider.

Under the direction of Commissioner Amanda Fritz, the Portland Water Bureau plans to seek public feedback on the type of filtration and other details of the project prior to moving forward with a future filtration plant. Opportunities to provide input will be announced in the next few weeks.

The public and the media are encouraged to view all sampling results posted to the City’s website at The bureau will notify the media and public immediately should further test results indicate a risk to public health and if precautions are necessary.

Customers with questions regarding water quality can call the Water Line at 503-823-7525.

TRAFFIC ADVISORY 9/18/2018: Southwest Broadway Drive One-Day Closure Scheduled

The intersection of Southwest Broadway Drive, Davenport Street and Davenport Court will be closed in all directions from 8 a.m. to 11 p.m. on Saturday, Sept. 22, or until construction is complete. Portland Water Bureau crews will be working in the intersection to install a new water pressure regulator to ensure safe and reliable water for the area.

Southwest Broadway Drive from 9th Avenue to Sherwood Drive will have local access restrictions, meaning only travelers within the restricted area will be allowed access. Residents on Southwest Davenport Court will be directed in and out of the construction site, but there will be delays.  

This work will be performed because the existing water pressure regulator is at the end of its productive life and must be replaced to ensure safe and reliable water in the future. The new regulator will be installed in Southwest Davenport Street to reduce future traffic conflicts at this intersection.

In an Emergency, Everyone Has a Role to Play

September is National Preparedness Month. At the Portland Water Bureau, we prepare as part of our daily work—hardening the backbone of our water system and building storage that will last for generations. In an emergency, everyone has a role to play. What’s your role?

One of the most important things you can do to prepare for an emergency is to have an emergency kit that includes water. People can survive for weeks without food, but only a few days without water. In the Pacific Northwest, your kit should be able to sustain your entire household (pets, too!) for 14 days. Experts predict that our region is overdue for a major earthquake that will severely damage water systems and other infrastructure. When this occurs, it will take time for emergency supplies to reach the greater Portland-metro area. You will need to rely on your own resources until help arrives.

Safely storing water for an emergency is an important step in getting your emergency kit together. Need help getting started?
