Middletown, PA carries a B grade while Bryn Mawr, PA carries a C. 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.

Bryn Mawr, PA is the larger of the two, with 1.0 million more residents than Middletown. Bryn Mawr is served by 14 public water systems, compared with 2 in Middletown — a difference of 12 systems. A larger number of systems often reflects a more fragmented distribution network spanning multiple utilities, suburbs, or rural service areas, while a single large utility serving a big population can benefit from economies of scale in treatment and monitoring, but may also face more complex, aging infrastructure to maintain.
