Although Mayor Sylvester Turner said Monday that water was likely safe to use again, the city's testing protocols mean its boil water notice will remain in effect until at least Tuesday.
"To ensure destruction of all harmful bacteria and other microbes, water for drinking, cooking, and ice making should be boiled and cooled prior to use for drinking water or human consumption purposes," the boil water notice stated.
Late on Sunday night, Mayor Turner said that city officials believed the water was safe to use, but regulatory requirements mandate that a boil water notice remains in effect until the Texas Commission on Environmental Quality has completed repeat testing on water samples, and confirmed they are not contaminated.
