Water boil advisory lifted after E. coli contamination

November 27, 2019

LIBERTY LAKE, Wash. (AP) — The Liberty Lake Sewer and Water District near Spokane says most of its customers no longer need to boil their water after a water sample from a fire hydrant tested positive for E. coli.

The sewer and water district said Wednesday it had isolated the area where the contamination was found, then disinfected and flushed the entire system. The boil water advisory will remain in effect for a very small portion of customers.

The water district found E. coli bacteria on Nov. 17 in water that served two homes. On Nov. 20, tests in an adjacent part of the system were also found to have E. coli bacteria.

The water system serves more than 10,000 people in Liberty Lake and the surrounding area approximately 12 miles (19 kilometers) from Spokane.
