Cancer Alley residents face cancer rates 47x the EPA acceptable level

Along an 85-mile stretch of the Mississippi River between Baton Rouge and New Orleans, more than 150 petrochemical plants and 15 refineries create a corridor where cancer incidence soars up to 47 times the EPA's acceptable rate. The people who bear this burden are predominantly Black residents of fence-line communities -- neighborhoods literally adjacent to refinery walls -- who breathe benzene, formaldehyde, and ethylene oxide daily. EPA-mandated fenceline monitors installed since 2018 have revealed that refineries underestimate their actual benzene emissions by up to 28-fold. Why does this hurt so deeply? These residents cannot simply move. Their homes, built on former plantation land, are worth a fraction of replacement cost because no buyer wants property next to a refinery. They are trapped in a health crisis with no exit: elevated rates of respiratory disease, kidney damage, reproductive disorders, and cancer, while lacking the financial resources to relocate or the political power to force plant closures. Why does it persist? The plants were deliberately sited on historically Black communities with less political power to resist. Louisiana's industrial tax exemption program (ITEP) has granted billions in tax breaks to these facilities, giving the state a financial incentive to protect them. Regulatory capture at the state level means enforcement is weak.
