Alabama Tap Water Quality

Overview
Most Alabamians drink surface water drawn from the Tennessee, Coosa, Cahaba, and Black Warrior river systems, treated by large regional utilities such as Birmingham Water Works and Huntsville Utilities. The big urban systems have strong compliance records and meet all federal Safe Drinking Water Act standards.
The state's defining water story is PFAS: decades of discharges from the 3M plant in Decatur contaminated the Tennessee River and forced downstream utilities in the West Morgan-East Lawrence area onto advanced filtration. Smaller rural systems in the Black Belt region also struggle with aging infrastructure and occasional monitoring lapses.
Common Contaminants in Alabama
Tennessee River systems downstream of Decatur carry a well-documented legacy of 3M-related PFAS contamination; affected utilities have added reverse osmosis or carbon treatment
River-sourced systems across the state chlorinate heavily in warm months; trihalomethane levels run closer to the federal limit in some small systems
Older housing in Birmingham, Mobile, and Montgomery can leach lead from private-side pipes and fixtures, as in most older US cities
Violations & Compliance
Alabama's large metro systems rarely record health-based violations. Enforcement actions concentrate in small rural systems, particularly in the Black Belt counties, where aging plants and thin budgets produce monitoring and reporting violations more often than actual contaminant exceedances.
