More than two dozen public schools in Detroit will remain closed Friday due to a boil water advisory covering parts of the city and the enclaves of Hamtramck and Highland Park.
The Detroit Public Schools Community District says that after the advisory is lifted water lines in the 29 schools will be flushed with running water prior to Monday morning's start of classes.
The Detroit schools were closed Thursday as a precaution following the advisory, which was announced earlier this week. Schools in Hamtramck were closed Thursday for a second-straight day.
An equipment malfunction at a Great Lakes Water Authority treatment facility on Tuesday caused low water pressure. The problem was addressed, but the advisory was issued due to concerns that bacteria could have gotten into the system.
