Frequently Asked Questions About Longtown Tap Water
Longtown's water has 3 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 17 health-based violations for LONGTOWN RW&SD #1 (PITTSBURG CO.) that began after its latest compliance result on file (Jul 2022): Maximum Contaminant Level Violation, Average (Total Haloacetic Acids (HAA5)), which began on October 1, 2025; Maximum Contaminant Level Violation, Average (TTHM), 16 violations, the first beginning on July 1, 2023 and the latest on October 1, 2025. Every such result predates them; its later EPA UCMR 5 results (Jan 2026) screen for unregulated contaminants and cannot show the water met this standard, so this page does not call the water safe.
