Baker City’s municipal water supply has been contaminated with a small amount of PHOS-CHEK WD881 Class A Foam Concentrate fire suppression foam. This chemical can cause skin and eye irritation, irritation to respiratory tract, if inhaled, and gastrointestinal irritation, nausea, vomiting and diarrhea if ingested.

The contamination was caused when the fire suppression foam entered the system during fire fighting efforts in the area of 10th and Baker Streets at approximately 7:00 a.m. on Tuesday, October 27, 2020.

Baker City Public Works has identified the known area of contamination from 8th Street to 11th and Broadway Avenue to ‘C’ Street. Crews have isolated and flushed the main lines within this twelve block area.

Water samples are in transit to a certified testing lab for analysis. It is expected that results will be received on Friday, October 30. Those results will be communicated to the public as soon as they are available.

Crews are continuing to flush lines in the area. It is expected that residents may experience reduced water pressure, air in lines, and possible debris from the turbidity cause by flushing.

All active water accounts will be receiving a 1-unit credit on their water bill to offset the cost of water used during the course of flushing their home systems.

As a precautionary measure, it is recommended that all residents and businesses flush their domestic water system. For instructions to complete this process please see, or call 541-524-2038 for recorded instructions. Instructions are also available at the front door of Baker City Hall, 1655 1st Street.
