Boil Water Advisory Issued in Tigard's Canterbury Hill Due to Potential ContaminationSource: Google Street View

Residents of Canterbury Hill in Tigard, just near SW McDonald Street and SW Pacific Highway, have been advised to boil their water before using it as a safety precaution due to potential contamination. According to the City of Tigard, the Boil Water Advisory was issued after a loss of water pressure yesterday could have let harmful bacteria seep into the water supply.

The specific areas affected fall within zone 530, which can be reviewed on the provided map. The city directs "Do Not Drink the Water without Boiling It First!  Bring all water to a boil, allow water to boil for one full minute and let the water cool before using." This caution extends to water used for drinking, making ice, brushing teeth, washing dishes, and preparing food. Bacteria of concern include fecal coliforms and E. coli, indicators of possible contamination from human or animal feces, which can lead to a range of illnesses, especially for those with weakened immune systems.

The mechanical failure that led to this advisory happened around 9:52 AM yesterday when a pressure-sustaining pump experienced issues and the city reports that their internal distribution team has since resolved the issue, with pressure returning to normal by 10:45 AM. The city's crews are currently flushing distribution waterlines in the area to help resolve the issue.

Until official test results confirm that the water supply is free of bacteria, the advisory remains in effect. These results are anticipated to be available later this afternoon, and, the city has committed to informing residents and lifting the boil water advisory when it is safe to resume normal water use. Tigard promises an update within 24 hours since the pressure loss, and residents are urged to stay tuned for the latest information.
