Grant, AL vs Huntsville, AL

When comparing tap water quality between Grant, AL and Huntsville, AL, Huntsville currently holds a noticeable 8-point lead in average WaterQ score, with a score of 100 out of 100 versus 92 for Grant. Both cities currently carry an A grade overall. A WaterQ score reflects an aggregate of EPA-reported violations, monitoring data, and compliance history across all public water systems serving each city, so a higher score generally indicates fewer recent violations and a stronger compliance record, though it does not guarantee that every tap in the city tests identically.

Huntsville, AL is the larger of the two, with 363,438 more residents than Grant, yet both cities are served by the same number of public water systems (2). This means the difference in population is handled by systems of different scale rather than a different count of utilities — larger systems generally serve more connections and may have more monitoring requirements under the Safe Drinking Water Act.
