Here in Southlake, every sip of water you take is the result of consistent testing, careful oversight, and a commitment to excellence from the team working behind the scenes every day. The 2026 Water Quality Report provides a transparent look at the water quality data collected throughout 2025 and confirms that Southlake’s drinking water met or exceeded all state and federal safety standards set by both the U.S. Environmental Protection Agency (EPA) and the Texas Commission on Environmental Quality (TCEQ).
The report is designed to help residents better understand their drinking water and includes:
• A summary of Southlake’s 2025 water quality results and regulatory compliance.
• Information about where your water comes from and how it is treated before reaching your home or business.
• An explanation of the testing and monitoring programs that help ensure water quality year-round.
• Additional details about water quality standards, conservation resources and ongoing efforts to protect our water supply.
“Providing safe, high-quality drinking water is one of our most important responsibilities,” said Hannah Nyquist, Environmental and Regulatory Supervisor. “The results in this year’s report reflect the dedication of our team and the rigorous testing and monitoring programs we have in place every day to ensure residents can have confidence in their water.”
Whether you want to dive into the numbers or simply learn more about how your drinking water is protected, you will find everything you need to understand the process that guarantees your water is clean and safe, thanks to the dedicated work of the Southlake Water Team.
