Kannapolis officials have issued a boil water advisory following the detection of E. coli in the drinking water. The advisory has prompted early dismissal of students in Kannapolis City Schools and led to temporary business closures and event cancellations. While some areas supplied by Concord have been cleared, the advisory continues for most residents. Firefighters in the city are distributing bottled water to help alleviate the situation. The community is advised to boil water before consumption until further notice.
