Boil Water Order Issued in Houston

More than 2 million people in the Houston area received a boil order notice Monday after a power outage caused low pressure at a water purification plant, authorities said.

The order means that water must be boiled before it is used for cooking, bathing or drinking. Several Houston-area public and private schools, as well as some local universities, closed Monday as a result of the advisory, while others made adjustments to provide bottled water and disinfectant to affected campuses. The warning was issued on Sunday after a power outage at a water purification plant, the city’s public works department said.

Testing of the water quality was underway, according to Houston officials.

Houston Mayor Sylvester Turner said on Twitter that the city believes the water is safe, but a boil order was required because the water pressure dropped below the minimum required by the Texas Commission on Environmental Quality. He said the water sampling would begin Monday morning and the boil order could be lifted 24 hours after the city is notified the water is safe.
