Cryptosporidium and Your Water
Routine monitoring of Bull Run water by the Portland Water Bureau in January and February revealed multiple detections of Cryptosporidium oocysts (oh-sists) from samples collected at the Bull Run intake. Cryptosporidium is a microscopic parasite found in infected animals or humans that can cause gastrointestinal illness. The City is working closely with the Multnomah County Health Department, State of Oregon Health Authority and wholesale water customers like TVWD as it assesses the situation.
What does this mean for customers?
Your water remains safe to drink and there currently is no evidence of an increased public health risk; however, if you have a weakened immune system, you should seek specific medical advice from your health care provider. The Water Bureau temporarily activated the groundwater source in an abundance of caution to ensure the continued protection of public health.
TVWD is a wholesale customer of Portland and purchases approximately 60 percent of its annual supply from the Portland Water Bureau. Valley View Water District receives 100 percent of its water from Portland. The Joint Water Commission is TVWD's other primary source, which utilizes a conventional water treatment plant designed to remove Cryptosporidium oocysts and other water-born parasites.
TVWD staff will continue to monitor the situation in coordination with Portland and the associated public health agencies as more information becomes available. The Portland Water Bureau FAQ page for Cryptosporidium is your best source for the latest information on the situation. For questions or concerns about your TVWD water, call 503-848-3000 (M-F, 7:00 a.m. to 4:30 p.m.) and ask for Water Quality, or email our Water Quality Department.
