Frequently Asked Questions About Ryan Tap Water
Ryan's water has 5 contaminants above EPA MCLGs. We strongly recommend using a certified water filter to reduce exposure to these contaminants. Check our filter recommendations below for NSF-certified options that can remove the specific contaminants found in Ryan's water. EPA records 2 health-based violations for JEFFERSON CO CONS RWD #1 that began after its latest compliance result on file (Jul 2022): Maximum Contaminant Level Violation, Average (TTHM), 2 violations, the first beginning on October 1, 2022 and the latest on January 1, 2023. Every such result predates them; its later EPA UCMR 5 results (Dec 2024) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
