• At least 34 people had undergone decontamination procedures, according to the fire marshal's office.
• Lina Hidalgo, Houston's chief elected official, said in a statement, "We've issued a closure order to investigate and ensure the park meets all requirements before reopening again."

What to watch: Neutzler said at a news conference that investigators were "looking into the system" that injected bleach and sulfuric acid to maintain the pH balance and keep pools clean "to see if there was a malfunction or not, but that's still under investigation," per the Times.
