A boil water advisory is in effect for several neighborhoods in Clemson. The advisory has been issued as a precaution because of low water pressure caused by a line tie-in on Downs Loop. It covers Downs Boulevard, Downs Loop, Hickory Way, Birch Place, Keystone Lane, Evergreen Drive, Hill Pine Court, and Berkeley Court. Residents in those neighborhoods should vigorously boil water for at least one minute before drinking or cooking—until otherwise notified by the city. Any ice made from water which has not been boiled should not be used for drinking purposes. Water samples have been taken and testing results are to be received by 4 o’clock this afternoon.
