A water system malfunction in Chatham County has authorities urging residents to boil their water, according to the News and Observer.

Areas directly affected include Fearrington Village, Briar Chapel, Hudson Hills, Galloway Ridge, Woods Charter School, Manns Chapel, Hamlet Grove, Prestonwood, and Monterrane.

The issue was first noticed when reports of low water pressure and outages came in from residents. Those problems could allow bacteria to get into the water pipes.

The cause of the malfunction is under investigation, but an official told the N&O that boiling water for one minute should eliminated any disease-causing bacteria.

The warning will remain in place until a written notice is delivered.
