Frequently Asked Questions About Adair Tap Water
Adair'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 MAYES CO RWD # 5 that began after its latest compliance result on file (Jul 2022): Maximum Contaminant Level Violation, Average (Total Haloacetic Acids (HAA5)), which began on July 1, 2025. Every such result predates it; its later EPA UCMR 5 results (Nov 2024) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
