Clarksville, TN Tap Water Quality

Water quality in Clarksville, TN is currently rated with a moderate C grade (average score: 68/100 across 5 ZIP codes). This rating indicates that while the water provided by Clarksville Water Department 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.

The accumulation of 25 health-based violations over the past 5 years highlights systemic challenges within Clarksville's water infrastructure. When violations occur, it means that drinking water tests revealed contaminant levels exceeding safe limits, triggering mandatory corrective actions by Tennessee Department of Environment and Conservation. The city relies on surface water, which may require significant treatment upgrades to address these recurring issues.

Fortunately, the modeled risk for widespread lead exposure in Clarksville'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.
