St. John the Baptist Parish between New Orleans and Baton Rouge sits in Cancer Alley — the corridor of petrochemical plants along the Mississippi River with some of the highest industrial pollution rates in the United States. The parish was devastated by Hurricane Ida in 2021 with LaPlace flooding catastrophically when the parish levee system was overtopped. The community has been at the center of environmental justice litigation over industrial air pollution.
