Frequently Asked Questions About Smithville Tap Water
Smithville'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 a health-based violation for SMITHVILLE WATER SYSTEM that began after its latest compliance result on file (May 2022): Maximum Contaminant Level Violation, Average (TTHM), which began on January 1, 2023. Every such result predates it; its later EPA UCMR 5 results (Oct 2023) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
