Oakland, NE vs Grand Island, NE

When comparing tap water quality between Oakland, NE and Grand Island, NE, Oakland currently holds a narrow 3-point edge in average WaterQ score, with a score of 97 out of 100 versus 94 for Grand Island. 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.

Grand Island, NE is the larger of the two, with 49,203 more residents than Oakland, 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.
