A water main break is causing problems in New Concord. Village officials say all customers from High Street south including Main Street are under a boil advisory until further notice. Customers are advised to boil all water used for drinking and cooking. Customers may experience low pressure or discolored water and should not do laundry until the water clears. Boil advisories are a required precautionary safety measure until laboratory testing confirms the safety of the water. Muskingum University and the John Glenn School campus are not affected by this advisory.
