A cold snap blanketing the Deep South has upended water systems as local officials struggle to repair widespread leaks and broken pipes, forcing some people to take drastic measures to get by without reliable access to running water. Breakdowns in infrastructure arose in rapid succession after days of freezing temperatures in areas where extended periods of frigid weather are abnormal. The water woes are acute in places like Jackson, Mississippi, where the water system partially collapsed in late August and has had repeated weather-related breakdowns. Jackson Mayor Chokwe Antar Lumumba said the city is dealing with a “worst case scenario” on Tuesday.
