Frequently asked
Is there lead in Fort Smith tap water?
FORT SMITH WATER UTILITIES's most recent lead 90th-percentile result (2023–2025) was 1 µg/L, below the 15 µg/L action level. It comes from sampled homes; your own pipes decide what reaches your tap.
Does Fort Smith have lead service lines?
In EPA's service line inventory (2026Q2), FORT SMITH WATER UTILITIES reported 1 lead service lines, 14 galvanized lines requiring replacement and 16,887 of unknown material, out of 49,594 lines in total. Unknown lines have not yet been identified and may include lead.
How do I know if my home has a lead service line?
Ask FORT SMITH WATER UTILITIES whether your address appears in its service line inventory, which utilities must publish. You can also look where the water pipe enters your home: lead pipe is dull grey, soft, and shows shiny metal when scratched gently.
How do I reduce lead in my water?
Run the cold tap for a few minutes after water has sat for hours, use only cold water for drinking and cooking, and use a filter certified to NSF/ANSI 53 for lead reduction. Replacing a lead service line removes the main source.
