HOUSTON—More than 2 million people in the Houston area were under a boil order notice Monday after a power outage caused low pressure at a water purification plant, officials said.
The order means water must be boiled before it’s used for cooking, bathing, or drinking. Multiple Houston area public and private schools, as well as some local colleges, were closed Monday as a result of the notice, while others made adjustments to provide affected campuses with bottled water and sanitizer. The warning was issued Sunday after a power outage at a water purification plant, the city’s public works department said.
