PFAS in Arkansas Drinking Water

PFAS in Arkansas: what the data shows
Arkansas has 137 cities with PFAS monitoring data from the EPA's UCMR 5 program. PFAS ("forever chemicals") were detected in 48 of those cities (35%), with very few cities exceeding the EPA's 2024 maximum contaminant levels of 4 ppt. The state average is better than the national average. 1 city exceeds the EPA MCL for at least one PFAS compound. PFAS are linked to cancer, immune system disruption, and developmental issues. The 2024 EPA rule requires water systems exceeding the MCL to notify customers and reduce levels by 2029. PFAS data comes from the EPA's Unregulated Contaminant Monitoring Rule 5 (UCMR 5), which required large water systems to test for 29 PFAS compounds between 2023–2025. Not all systems have completed testing — cities without data may still have PFAS present.

Frequently asked questions about pfas in Arkansas
Does Arkansas tap water contain PFAS?
PFAS were detected in 48 of 137 Arkansas cities tested under EPA's UCMR 5 program. 1 city exceeds the 2024 EPA MCL of 4 ppt for individual PFAS compounds.
How can I remove PFAS from my drinking water in Arkansas?
Reverse osmosis (RO) systems are the most effective at removing PFAS, typically removing 90%+ of compounds. High-quality activated carbon block filters (NSF 58-certified for RO, or NSF 53 for solid carbon) also provide significant reduction. Standard pitcher filters vary widely in PFAS removal.
