Track record
0health-based violations in the last 10 years
From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.
Your household
Your tap can differ from the city record
The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.

Lead service lines
Ask your utility first

Local help
Think your plumbing may be adding lead?
Call to be connected with a local plumbing provider about lead service lines, repiping or fixture replacement.
Your path: I live in an older buildingLead from plumbing is the main question
Older buildings may have lead service lines, solder or fixtures. Bentonville’s record shows lead at 1 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
1 of 29 PFAS tested was detected in Bentonville’s record (6:2 FTS 6.2 ng/L). If PFAS matters to you, a filter certification names each compound it covers.
Look forNSF/ANSI 53 or 58, with each compound you care about named on the listing
Your path: My water tastes of chlorineThe disinfectant is not in this record
Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.
PurityMap does not give a safe/unsafe verdict; it shows what the public records measured. For Bentonville, 6:2 FTS 6.2 ng/L was detected, with no federal or state limit; the lead 90th-percentile result was 1 µg/L against the 15 µg/L action level. BENTONVILLE WATER UTILITIES (PWSID AR0000041) has a Purity Score of 99/100 (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. What we found →
