Alabama Legionella Compliance & Water Quality Standards
Executive Overview
Alabama enforces healthcare water safety compliance via the Alabama Department of Public Health (ADPH) under Ala. Admin. Code r. 420-5-7 and CMS QSO-17-30. Facilities must maintain documented ASHRAE 188 Water Management Plans, monitor disinfectant residuals, and maintain hot water loops at bactericidal temperatures.
