Jan. 4, 2019: Cryptosporidium Monitoring Update

Crypto updateThe Portland Water Bureau received results from ongoing monitoring from the Bull Run Watershed intake for Cryptosporidium, a potentially disease-causing microorganism. One Cryptosporidium oocyst was detected in a sample collected Monday, Dec. 31, two oocysts were detected in a sample collected Wednesday, Jan. 2. Cryptosporidium was not detected in the samples collected on Dec. 30 and Jan 1.  Prior to these detections, Cryptosporidium was last detected from the Bull Run Watershed intake on Dec. 24.

The bureau continues to use the Bull Run as its primary source of drinking water. 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 September 2027 under a compliance schedule with 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 Centers 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 or 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.

About Cryptosporidium

The Environmental Protection Agency has estimated that a small percentage of the population could experience gastro-intestinal illness from Cryptosporidium and advises that customers who are immunocompromised and receive their drinking water from the Bull Run Watershed consult with their healthcare professional about the safety of drinking the tap water.
