About Tap Water in Osage, WY

The drinking water in Osage, WY generally meets all federal health standards, earning a solid B grade with a composite safety score of 82/100 across 1 ZIP code. While the primary water utility, Osage Water District, maintains adequate compliance with EPA regulations, there have been minor or administrative violations on record. Overall, residents receive safe tap water that is actively monitored by U.S. EPA Region 8 (Direct Implementation).

Over the past 5 years, Osage has recorded 1 health-based violation. While occasional violations can occur due to seasonal changes or temporary infrastructure issues, Osage Water District 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 Osage'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.
