The affected areas include Mount Vernon Road, Highway 178, County Roads 203, 183, 461, 461 and parts of 141. No specifics on the number of households affected by the boil water notice were available on Thursday afternoon.
The boil water notice is a precaution because a break in the pressurized water lines can allow bacteria to enter the system.
The line break was being repaired on Thursday evening. The water will have to be tested twice before the boil water notice can be lifted.
