Based on recent EPA Safe Drinking Water Act compliance records, water provided by City of Kerrville 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.

The accumulation of 8 health-based violations over the past 5 years highlights systemic challenges within Kerrville's water infrastructure. When violations occur, it means that drinking water tests revealed contaminant levels exceeding safe limits, triggering mandatory corrective actions by Texas Commission on Environmental Quality (TCEQ). The city relies on surface water, which may require significant treatment upgrades to address these recurring issues.

Additionally, lead exposure risk remains a critical issue for certain neighborhoods. EPA data indicates that 1 out of 2 ZIP codes in Kerrville are rated as High or Very High risk for lead. This risk is often driven by aging homes with pre-1986 plumbing containing lead solder or service lines. Families in these areas should test their tap water and consider NSF/ANSI 53 certified filters.
