Residents who use the Raft Island Water System west of Gig Harbor were told to boil their drinking water after E. coli was found this week, the state said Thursday.
About 520 people use the water system in Carr Inlet.
They should boil water used for drinking, brushing teeth, making food, ice and washing dishes, the state Department of Health said. Water boiled for a minute is safe to use, the state said.
The Washington Water Service Company runs the system, and is working with the state to confirm the bacteria the initial results showed, the health department said.
