BRIGHTON, Colo. - The city of Brighton is planning to use a super-chloride flush to disinfect 18 homes possibly connected to two positive E. coli tests this week.
A boil order was issued Wednesday for all residences and businesses that are connected to the City of Brighton's water system.
A second test came back positive on Thursday afternoon, forcing officials to keep the boil order in place until further notice.
Brighton Mayor Dick McLean said more test results are due back Friday afternoon. It takes 24 hours for bacteria culture test results.
"We have been able to identify the problem in one area and are isolating those homes from the city-wide system," officials said. "We will be performing additional tests on homes in the near vicinity to determine exactly where the problem is occurring."
Those 18 homes are without water service.
Brighton's city manager said there are no confirmed cases of E. coli illnesses yet. However, some residents have told 7NEWS they have been sick recently.
According to the city’s advisory, residents are instructed to not drink tap water without boiling it first. "Bring all water to a boil, let it boil for three minutes, and let it cool before using, or use bottled water," the advisory states. "Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice. Boiling kills bacteria and other organisms in the water."
