What Louisiana's water readings can explain
Utility-reported data for Louisiana includes manganese and sulfate โ the readings behind these common tap water questions. We publish a city-level hardness figure for Louisiana, resolved from its water systems where they report one and estimated from county sampling where they do not.

Frequently Asked Questions About Louisiana Tap Water
Louisiana's water has 2 contaminants above EPA MCLGs. We recommend using a certified water filter for additional protection, especially for vulnerable populations like children, pregnant women, and those with compromised immune systems. EPA records 10 health-based violations for LOUISIANA PWS that began after its latest compliance result on file (Dec 2020): Maximum Contaminant Level Violation, Average (Total Haloacetic Acids (HAA5)), 4 violations, the first beginning on July 1, 2024 and the latest on January 1, 2026; Maximum Contaminant Level Violation, Average (TTHM), 6 violations, the first beginning on July 1, 2021 and the latest on January 1, 2025. Every such result predates them; its later EPA UCMR 5 results (Dec 2025) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
