Questions

Frequently asked questions

Is Fort Smith tap water safe to drink?

PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Fort Smith, no regulated PFAS were detected in EPA's 2024 testing; the lead 90th-percentile result was 1 µg/L against the 15 µg/L action level. FORT SMITH WATER UTILITIES (PWSID AR0000507) has a Purity Score of 98/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured. Water can change in your own pipes, so a certified test is the only way to know what comes out of your tap.

Who provides tap water in Fort Smith?

FORT SMITH WATER UTILITIES (PWS ID AR0000507) is the public water system on record for Fort Smith, Arkansas, serving about 86,209 people. Confirm the utility on your water bill before acting on a specific finding.

Where does Fort Smith get its drinking water?

Surface water (primary source of record in EPA SDWIS).

Are PFAS "forever chemicals" in Fort Smith's water?

None of the 29 PFAS in EPA's UCMR 5 testing (2025-03-05 to 2025-12-03) was detected. "Not detected" means below the lab's reporting limit, not proven zero.

Is there lead in Fort Smith's 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. That figure comes from sampled homes; lead usually enters from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.

What does the latest Fort Smith water report show?

PurityMap's current record for Fort Smith holds 31 findings: 1 detected within the reference and 30 not detected. Each finding links to its dated public record; a parameter that was never monitored is shown as pending, not as a pass.
