Notification

Cryptosporidium Detections on November 1, 2019

The Portland Water Bureau detected Cryptosporidium, a potentially disease-causing microorganism, in water samples collected on November 1, 2019.

The Tualatin Valley Water District (TVWD) purchases a portion of their annual drinking water supply from the Portland Water Bureau. Customers living in the Butternut Creek neighborhood in South Hillsboro are being temporarily served drinking water by TVWD. Customers who live in the Butternut Creek neighborhood may be receiving water that comes from the Portland Water Bureau.

The State has determined that the public does not need to take additional protections at this time. The City of Portland will continue increased sampling four times per week until there are at least three weeks without any detections.

The City of Hillsboro and TVWD will continue to monitor the situation in close coordination with the Portland Water Bureau and the local public health agencies. 

Questions:


Butternut Creek is one of three new mixed-use developments under construction in the South Hillsboro neighborhood. The Butternut Creek development is located south of SW Tualatin Valley Highway and north of SW Rosedale Road off SE Butternut Creek Parkway.

Water Service

The Hillsboro Water Department serves nonfluoridated water to the part of City of Hillsboro west of Cornelius Pass Road and south of Highway 26 (Sunset Highway), except for the South Hillsboro Butternut Creek Neighborhood. The Hillsboro Water Department also provides water to customers in western Washington County who live along Hillsboro's original service line.

While located within the City of Hillsboro, customers living in the South Hillsboro Butternut Creek neighborhood will be temporarily served fluoridated water from Tualatin Valley Water District (TVWD) until Hillsboro’s water pipeline construction in that area is completed. 

The two other developments in South Hillsboro, Rosedale Parks and Reed's Crossing, will be served nonfluoridated water by the Hillsboro Water Department. 

After pipeline construction is complete, the Butternut Creek neighborhood will be switched to receive the Hillsboro Water Department’s nonfluoridated water. Notification to affected residents will occur at that time.
