On March 14, 2012, the Oregon Health Authority (OHA) issued the Portland Water Bureau a 10-year variance from treating Bull Run drinking water for Cryptosporidium. As a result of the variance, the bureau became the only surface water system in the country that did not have to treat for Cryptosporidium. The treatment variance was issued in accordance with federal and state regulations.
Starting in January 2017 and continuing through March 2017, the bureau detected low levels of Cryptosporidium in several raw water samples from the Bull Run Watershed. A total of 19 individual Cryptosporidium oocysts were detected at the intake over this timeframe. On May 19, 2017, the bureau received a letter from OHA, the bureau’s regulatory authority, revoking the variance effective no later than September 22, 2017.
In order to remain in compliance with state and federal regulations, the bureau must submit its treatment and interim control measures plans to OHA by August 11, 2017. As a result, the bureau responded to a request from City Council to present treatment options during a June 27, 2017, Council work session. During the session, Commissioner Nick Fish encouraged public comment on this matter.
Bureau staff will deliver public comments to City Council weekly. A compilation of comments will be delivered to City Council on July 31, in order to ensure enough time for review before the City Council meeting on August 2.
To ensure your comments are included, please submit them by noon on July 31.
