NEW MEXICO: Her elderly neighbor is hard of hearing so Maria Luisa Robles, a convenience store worker in the northern Mexican city of Monterrey, shouted the question a second time: Have you run out of water? She had – and it wasn’t just her. The taps across this working-class neighborhood of Sierra Ventana dried up over a week ago amid a historic shortage that’s gripped the most important industrial city in Mexico. We’re all struggling because there’s no running water, said Robles, 60. Desperate, Robles and her neighbors have resorted to climbing atop a nearby municipal water tank, filling up jugs, and lugging them back to their homes in order to drink, cook, clean, and wash bedsheets and school uniforms. –Agencies
