Frequently Asked Questions About Port Arthur Tap Water
Port Arthur'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 2 health-based violations for CITY OF PORT ARTHUR that began after its latest compliance result on file (Jun 2022): Single Turbidity Exceed (Enhanced SWTR) (Interim Enhanced Surface Water Treatment Rule), 2 violations, the first beginning on February 1, 2024 and the latest on January 1, 2025. Every such result predates them; its later EPA UCMR 5 results (Apr 2024) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
