Baton Rouge - The Louisiana Department of Health (LDH) has released the 2025 letter grades for community water systems across the state, offering a transparent look at the quality and performance of more than 900 systems serving Louisiana residents.
This annual report card, mandated by the Community Drinking Water Accountability Rule (Act 98 of the 2021 Regular Legislative Session), provides residents with clear, accessible information about the systems that deliver their drinking water.
The latest report shows continued progress statewide, with fewer water systems receiving failing grades and more systems demonstrating measurable improvements in performance.
The water grading system, authorized in 2021, is part of the Safe Drinking Water Program’s broader effort to strengthen accountability among water providers while empowering consumers with clear information about their drinking water. The grades are calculated using a standardized 100-point scale based on seven critical categories: • Federal Water Quality Compliance
• State Water Quality Compliance
• Financial Sustainability • Operation and Maintenance
Water
