North Texas Municipal Water District’s (NTMWD) top priority is to keep drinking water safe.

That’s why we continuously monitor and test an average of 685 samples every day to ensure drinking water meets or exceeds regulatory, health and aesthetic standards set by the Texas Commission on Environmental Quality, the U.S. Environmental Protection Agency and the Clean Water and Safe Drinking Water Acts.

To ensure quality water at the tap, our state-certified laboratory conducts numerous analyses on more than 250,000 samples collected each year. We publish the levels of all regulated contaminants detected in our drinking water in an annual Consumer Confidence Report.

Additionally, the water providers we service also test water before they distribute it to residents and businesses, and produce an annual Consumer Confidence Report as well.
