Louisiana has 125 active non-transient non-community water systems, 11% of the state's 1,121 active systems. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 966 Louisiana systems (86%) list groundwater as their primary source.

Does Citgo Petroleum Refinery Water System have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in January 2024. The violations listed here began between March 2007 and January 2024. By type: 9 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them).
