Frequently Asked Questions

Is there pfas (per- and polyfluoroalkyl substances) in Arkansas water?

Yes. Arkansas has a 18.4% PFAS detection rate across 152 tested water systems. 0 systems exceed the EPA 4 ppt MCL for PFOA/PFOS.

How can I check my Arkansas water for pfas (per- and polyfluoroalkyl substances)?

Search for your water system using the WaterCheck system lookup, or contact your utility and request a copy of your Consumer Confidence Report (CCR). The CCR is published annually and lists all detected contaminants, their levels, and the EPA MCLs. For private wells, contact a state-certified lab for independent testing.

What is the EPA limit for pfas (per- and polyfluoroalkyl substances)?

The EPA Maximum Contaminant Level (MCL) for pfas (per- and polyfluoroalkyl substances) is 0.000004 mg/L. Systems that exceed MCLs are required to notify customers and take corrective action.

How to Filter PFAS (Per- and Polyfluoroalkyl Substances)

  • +Reverse osmosis is most effective against PFAS (90-95% removal)
  • +Granular activated carbon (GAC) filters reduce some PFAS
  • +Look for NSF/ANSI 58 or 62 certified systems
  • +Standard pitcher filters offer limited protection
