Our Water Meets or Exceeds All Federal (EPA) Requirements

This report summarizes the quality of water we provide to our customers, using data from the most recent EPA-mandated tests. Where does our water come from? Flower Mound (PWS #0610023) purchased 4,880,788,000 gallons of treated water from Dallas Water Utilities (DWU) and Upper Trinity Regional Water District (RWD). All water is surface-sourced from lakes and rivers, primarily Lake Lewisville, but also Lake Ray Hubbard and Lake Tawakoni.

The TCEQ Source Water Susceptibility report details potential contaminants that may contact our water source due to human activities and natural conditions. For more information about source water assessments and protection efforts, please call 972.874.6400.

Additional Water Components

Components like calcium, sodium, and iron naturally occur in water at varying concentrations and can affect taste, color, and odor. Texas regulates these secondary components but doesn't consider them health concerns. While not included in this report, monthly test results are available upon request.

All Water Contains Some Contaminants

When water meets federal standards, there may be no health-based benefits to purchasing bottled water or point-of-use devices. All water, including bottled water, reasonably contains at least small amounts of contaminants. Their presence doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, call the EPA's Safe Drinking Water Hotline at 800.426.4791.

Cryptosporidium Information

Cryptosporidium is a microscopic intestinal parasite naturally found in the environment. While filtration removes most Cryptosporidium, even the most advanced filtration methods cannot guarantee 100% removal. Our water providers regularly test both treated and untreated water, finding it only in untreated sources (lakes and rivers). Most people with healthy immune systems overcome effects within weeks, but immunocompromised individuals face greater risks. We encourage at-risk individuals to consult their doctors about appropriate precautions.

Water Quality Monitoring Results

The following tables list all federally regulated or monitored substances found in your water. EPA requires water systems to test up to 80 constituents. As shown, Flower Mound's water met or exceeded all established requirements. Tables identify contaminants detected during 2017 or the most recent testing period.
