Based on recent EPA Safe Drinking Water Act compliance records, water provided by City of Stephenville and other municipal suppliers has consistently met or exceeded federal safety standards. This top-tier "A" grade reflects strong infrastructure, diligent monitoring by Texas Commission on Environmental Quality (TCEQ), and low contaminant levels.

Over the past 5 years, Stephenville has recorded 2 health-based violations. While occasional violations can occur due to seasonal changes or temporary infrastructure issues, City of Stephenville is legally required to resolve these quickly and notify the public via their annual Consumer Confidence Report.
