Alabama context

Tornado risk + rural water systems

Alabama sits in Dixie Alley with peak tornado activity in March-April. Coastal Mobile/Baldwin counties also carry FEMA-mapped storm-surge zones. Many rural water systems serve <500 connections, making EPA SDWIS compliance variability higher than in metro counties.

See Alabama state page for the full state-level rollup across all 12 dimensions.
