Corpus Christi lifts water ban after tests find no corrosive

A nearly four-day ban on drinking the water in Corpus Christi, Texas, was lifted on Sunday after test results showed no contamination due to a chemical leak, the city’s mayor announced. None of the 28 drinking water samples the Environmental Protection Agency reviewed tested positive for Indulin AA-86, an asphalt-emulsifying agent that’s corrosive, the federal agency said Sunday in a statement.
