EDISON - New Jersey American Water continues to advise its customers in West Orange, Short Hills, Millburn, Maplewood, Irvington, Springfield and Summit to boil their water as a precaution after flooding from Hurricane Irene inundated a water treatment plant in Essex County.

American Water officials say the advisory will remain in place for at least another day as they test samples to ensure they meet state and federal standards.

The company is also working to restore water service to customers in West Orange, Millburn, Maplewood, Irvington, and Springfield, who have been out of water or experienced low pressures since Sunday afternoon.
