About Tap Water in Troy, MO

Water quality in Troy, MO is currently rated with a moderate C grade (average score: 69/100 across 1 ZIP code). This rating indicates that while the water provided by Troy Public Water System is treated and regulated, there have been notable compliance issues or contaminant detections recently. Residents should stay informed about the specific challenges affecting their local supply.

Over the past 5 years, Troy has recorded 1 health-based violation. While occasional violations can occur due to seasonal changes or temporary infrastructure issues, Troy Public Water System is legally required to resolve these quickly and notify the public via their annual Consumer Confidence Report. The city's water supply, primarily drawn from ground water, is treated to address these specific contaminants.

Fortunately, the modeled risk for widespread lead exposure in Troy's municipal water is relatively low compared to national averages. However, because lead typically enters drinking water through the corrosion of older, individual home plumbing rather than the main supply lines, residents in homes built before 1986 should still exercise caution by running the tap before use.
