Your water quality is our top priority

Southern Nevada’s drinking water is tested from thousands of samples, including those drawn in neighborhoods throughout the community.

Scientists and technicians with the Southern Nevada Water Authority (SNWA) test your water more than 301,000 times a year, monitoring for more regulated and unregulated contaminants than is required by federal and state law.

SNWA technicians test your drinking water directly from Lake Mead, the source of 90 percent of our community’s supply.

Our community’s drinking water meets or surpasses all state and federal standards—and is tested more thoroughly and frequently than most bottled water.

The River Mountains Water Treatment Facility is one of two state-of-the-art facilities where Southern Nevada’s drinking water is treated above and beyond state and federal guidelines.

Still, some folks might shy away from tap water due to its hard, mineral-rich taste, while others mistakenly confuse taste with safety. While your tap water is perfectly safe for you and your family, if the taste doesn’t appeal to you, here are some tips you can use to improve its flavor:

• Place a pitcher of tap water in your fridge to help boost its flavor and zap chlorine perceptions.
• Add a slice of lemon to give your water some zest.
• Try an activated carbon filter, like those in carafe systems, to reduce chlorine taste.
• If you have an in-home filtration system, follow its recommended maintenance schedule, including filter replacement.

Local water providers—including the Las Vegas Valley Water District, the Big Bend Water District, and the cities of Boulder City, Henderson and North Las Vegas—will be publishing their annual water quality reports. These reports provide detailed information about what’s in your drinking water and reflect the results of rigorous laboratory testing and advanced treatment by SNWA scientists.
