"GALENA PARK, Texas —  Cindy Sanchez began to feel ill while barbecuing just before Harvey's torrents started pelting this city just east of Houston, along a corridor with the nation's highest concentration of petrochemical plants.

"I started getting really, really bad headaches," said Sanchez, a 32-year-old housewife. "I never get headaches."

"My husband's eyes were burning," she said. "He actually had a napkin that was wet over his eyes." The sewage-like stench chased the couple indoors and Sanchez, sick to her stomach, lay down."
