COURTESY MAP: CITY OF HILLSBORO - A map shows an area of the Jackson School neighborhood of Hillsboro where water customers are being directed to boil tap water until further notice after an emergency water leak repair caused a loss of water pressure in the area Friday, Sept. 17.People in an area of the Jackson School neighborhood of Hillsboro are being asked to boil tap water after an emergency water leak repair caused a loss of water pressure in pipelines serving the area.

The loss of pressure occurred Friday morning, Sept. 17, during repairs to a pipe on Northeast Harewood Street, Hillsboro officials said in a statement Friday afternoon.

The Oregon Health Authority's drinking water program has required the Hillsboro Water Department to issue a boil water notice for affected customers, officials said.

Until further notice, the directive affects water customers south of Northeast Harewood Place, west of Northeast Jackson School Road and east of Northwest Glencoe Road, officials said.

People should boil tap water for at least one minute for drinking, food preparation, tooth brushing and ice-making, officials said.

As a precaution, anyone in or near this area who lost water or had reduced water pressure should boil water, they said.

"While the potential health risk is relatively small, we are taking every precaution to protect public health," said Niki Iverson, director of the Hillsboro Water Department.

Using boiled and bottled water will ensure public health protection until the city can determine that the water system is clean of contamination through sampling, officials said.

Affected customers will be notified when they no longer have to boil their water.

Iverson said she couldn't confirm at this time what caused the emergency water leak that prompted repairs on a pipe.

Hillsboro staff currently are flushing water in the affected area and completing repairs on the water leak, officials said.

Samples will be taken to confirm the repair was successful and water is safe to drink, they said, adding water testing results are expected in about 24 hours.

Hillsboro officials are working with the Washington County Health Department to provide health-related information.

Customers can visit to determine if their home is in the boil water notice area.

Officials advised people not to call 911 unless they have an emergency.
