MONTCLAIR - A boil water advisory has been issued for the residents and businesses of one building in Montclair.

The order was given early Wednesday after a water main break happened on South Park Street. Any residents or businesses within the Siena Building on both Church and South Park streets are asked to boil their water before using it for consumption.

The township says some customers could see outages or experience a significant loss of pressure.
