Frequently Asked Questions About Maynardville Tap Water
Maynardville's water has 1 contaminant 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 MAYNARDVILLE WATER DEPT that began after its latest compliance result on file (May 2022): Treatment Technique (SWTR and GWR) (Surface Water Treatment Rule), which began on April 1, 2023. Every such result predates it; 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.
