State system profile

PFAS in North Carolina drinking water

Active community water systems with complete EPA UCMR 5 monitoring, summarized using yearly averages from results available through January 15, 2026.

Source EPA UCMR 5 Period 2023–2025 Systems included 254 Release ucmr5-2026-01-15-analysis-v0.2
Systems with a yearly average at or above an EPA-based study benchmark
24.0%61 of 254 active community water systems

All 254 systems had enough required samples to calculate a yearly average. 61 had at least one yearly average at or above a study benchmark; 193 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 North Carolina's state-specific standards or determine compliance. Use the official state or territory drinking-water program for current regulatory information.
