The boil water advisory has been lifted in York County, South Carolina, the city of Rock Hill tweeted Friday afternoon.
Water samples from all areas of the county have been tested by South Carolina's environmental department and have been cleared for use.
A Rock Hill news release said water might be slightly discolored at first or sputter as air is cleared from the lines. Flushing the water might help in those situations. Rock Hill also answered several commonly asked questions after a drinking water advisory on its website.
The city had asked residents to boil water since a water main broke Wednesday, disrupting service for 120,000 residents of York County.
