Ten of LaSalle Parish’s 12 water systems received an “A” recently with the release of the Louisiana Department of Health’s (LDH) 2025 Water System Grade Report. The report documented the fact that parish water systems are producing high quality water and service. Every year the state is required by law to develop a letter grade for each water system in the state as part of its community water system accountability. According to LDH, the letter grade is reflective of each water system’s quality and performance. Systems are graded on federal water quality, state water quality, financial sustainability, operation and maintenance, infrastructure, customer satisfaction and secondary contaminants (iron and manganese). The grading system used by LDH starts each system with 100 points and then takes deductions for various violations, issues and other problematic deficiencies.
