Cosmopolis water-main break prompts boil-water advisory; samples clear system

Cosmopolis officials said a water-main break on Jan. 12 disrupted service to the lower flats of the city and led to a temporary boil-water advisory affecting roughly 200 to 300 customers.

Mayor Springer told the council that the leak was first noticed by an officer and that city and Aberdeen crews responded quickly to isolate and repair the damaged main. "We ended up getting, putting notices out right away," the mayor said, describing the city's immediate outreach to residents.

Chris Sorkin, the operator for Community Water Systems, said the break was noticed around 2 p.m. and Aberdeen crews were on site by about 3 p.m. "I think we impacted 2 to 300 customers," Sorkin said. He said the utility collected three distribution samples for coliform bacteria and that "all of them came back satisfactory." He added that service was restored and the system was repressurized by approximately 6 p.m. on the day of the repair.

Sorkin and the mayor said the operator followed state guidance: they contacted the Washington State Department of Health duty officer and county health, and together decided to issue the advisory because of a pressure loss in part of the system. The advisory was lifted on Jan. 14 after satisfactory lab results.

Council members asked about health effects and testing: Sorkin described the samples as standard coliform tests and said gastrointestinal symptoms could occur if contaminated water were consumed, advising residents to follow the boil-water guidance while the advisory was in effect. He also explained that short-term cloudiness or discoloration after a pressure event is often caused by entrained air or sediment stirred in piping and usually clears within a few days.

Several speakers and a public commenter urged the city to expand notification methods beyond social media; Kim, a resident who spoke during public comment, said she preferred a text message or phone call and would rather receive targeted street-level alerts than rely on Facebook. The council and staff said they are developing communications improvements, including a dedicated public-works email for consolidated reports and options to use reverse-911 or targeted notifications through county emergency management when larger areas are affected.

City officials said there was no evidence of bacterial contamination following the sampling, and they encouraged residents who continue to see discolored water to flush lines and to contact the city via the new public-works channel. The city did not announce any fines or enforcement actions related to the break.
