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 Tokai Carbon Cb have drinking water violations?

Of the 12 most recent violations in EPA's records, 10 are health-based, and the most recent began in January 2026. The violations listed here began between January 2019 and January 2026.
