Frequently Asked Questions About Leonidas Tap Water
Leonidas'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 3 health-based violations for Eveleth that began after its latest compliance result on file (Jul 2022): Maximum Contaminant Level Violation, Average (Total Haloacetic Acids (HAA5)), 3 violations, the first beginning on July 1, 2025 and the latest on January 1, 2026. Every such result predates them; its later EPA UCMR 5 results (Oct 2024) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
