Systems with a yearly average above an EPA comparison level
0.0%0 of 170 active community water systems
All 170 systems met the sampling requirement for a yearly average. Of those systems, 0 had at least one yearly average above an EPA comparison level and 170 did not.
EPA-based study benchmark: a fixed, unrounded research cutoff used to reproduce EPA’s final UCMR 5 technical-assistance classification based on the April 2024 federal levels. It is not a current federal or state standard. The label does not determine compliance, household exposure, or health risk.
State rules: The labels on this page use fixed research cutoffs based on the April 2024 federal levels. Arkansas may use different current standards or guidance. These UCMR 5 results do not determine current federal or state compliance. Find the official Arkansas drinking-water program →

Community water systems with complete monitoring
“Complete monitoring” means at least one sampling location had every required sample needed to calculate a yearly average. It does not mean every location or home was tested. Each PWSID appears once, preventing double counting across ZIP associations.

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. Private wells are excluded, and UCMR 5 did not comprehensively monitor every small system.
