Smithfield, RI carries a B grade while West Greenwich, RI carries an A. 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.

West Greenwich, RI is the larger of the two, with 79,319 more residents than Smithfield, yet both cities are served by the same number of public water systems (1). 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.
