Park Forest, IL vs Godfrey, IL

When comparing tap water quality between Park Forest, IL and Godfrey, IL, Park Forest currently holds a narrow 2-point edge in average WaterQ score, with a score of 86 out of 100 versus 84 for Godfrey. Both cities currently carry a B 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.

Godfrey, IL is the larger of the two, with 744,715 more residents than Park Forest. Godfrey is served by 35 public water systems, compared with 1 in Park Forest — a difference of 34 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.
