Which City Has Better Water Quality?

Grand Island, NE and Omaha, NE currently share an identical average WaterQ score, each scoring 94 out of 100. Both cities currently carry an A grade overall. Because a WaterQ score is an aggregate across all public water systems serving a city, near-identical scores can still mask differences at the system level, so residents of either city should review their specific water system's record for the most relevant detail.

Omaha, NE is the larger of the two, with 608,049 more residents than Grand Island, 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.
