Who regulates water systems in Louisiana

Louisiana's state primacy agency administers the drinking water program under EPA oversight. Orevant tracks both the federal baseline and state-specific requirements.

Federal baseline requirements — coliform monitoring, lead and copper, disinfection byproducts, Consumer Confidence Reports, PFAS, and lead service line inventories — apply to Louisiana systems alongside state rules.

What Louisiana systems typically track

• Routine coliform sampling on a state-approved siting plan
• Lead and copper tap sampling and service line inventory updates
• Consumer Confidence Report delivery (community systems)
• Operator certification renewals
• PFAS monitoring under the 2024 federal rule
• Sanitary survey corrective actions
