Systems with a yearly average at or above an EPA-based study benchmark
7.5%11 of 146 active community water systems
All 146 systems had enough required samples to calculate a yearly average. 11 had at least one yearly average at or above a study benchmark; 135 did not.
EPA-based study benchmark: the unrounded cutoff this research uses to reproduce EPA’s January 2026 technical-assistance classification around the April 2024 federal levels. It is not a current standard or compliance finding and cannot determine household exposure or health risk.

How the count works
What is included
Each active community water system with enough required samples for a yearly average is counted once, even if it is linked with several ZIP codes. This does not mean every home was tested. Private wells are excluded, and UCMR 5 did not comprehensively monitor every small system. This page does not apply Virginia's state-specific standards or determine compliance. Use the official state or territory drinking-water program for current regulatory information.
