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.
Each card names which Jackson findings its current certification covers, and which it doesn't.

Your path: I live in an older buildingLead from plumbing is the main question
Older buildings may have lead service lines, solder or fixtures. Jackson’s record shows lead at 1 µg/L (15 µg/L federal action level). Test first-draw water, then filter if needed.
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 Jackson, PFAS were detected below the federal limits; the lead 90th-percentile result was 1 µg/L against the 15 µg/L action level. JACKSON, TOWN OF (PWSID WY5600213) has a Purity Score of 72/100 (confidence: moderate), assessed at the water-system level and computed only from contaminants that were measured.
