The Las Vegas Valley Water District (LVVWD) has released its annual Water Quality Report, which reveals that water delivered by the LVVWD meets or surpasses all state and federal safe drinking water standards.
The Water Quality Report, which is being mailed to LVVWD customers and is also available online at lvvwd.com, contains important information about drinking-water sources, treatment, testing, and a detailed analysis of regulated and unregulated contaminants based on 2019 water-quality test results. The report also includes information about our community’s water supply and how frequently it is tested.
In 2019, water quality scientists conducted nearly than 302,000 analyses on more than 56,000 water samples taken from Lake Mead, from storage reservoirs and 367 sampling stations throughout the water distribution system. In addition, water is continually monitored 24 hours a day, 365 days a year.
“Efficiently providing high-quality drinking water for Southern Nevada is our top priority,” said John Entsminger, LVVWD and Southern Nevada Water Authority (SNWA) General Manager. “Through our leading-edge water treatment and distribution systems and our comprehensive water quality monitoring processes, we safely deliver water to homes and businesses across our valley each day. Our community knows that every time they turn the tap, we will meet the demand with reliable, quality drinking water.”
Southern Nevada’s water quality scientists monitor for 91 regulated contaminants as required by the U.S. Environmental Protection Agency, as well as more than 75 unregulated contaminants to help protect the Las Vegas Valley’s drinking water. Most of the test results are reported in parts per billion (ppb)as the unit of measurement. One part per billion is similar to:
- One pinch of salt in 10 tons of potato chips
- One second in more than 30 years
- One inch in 16,000 miles
- One square of toilet paper in a roll stretching from New York City to London
The SNWA operates two water treatment facilities capable of producing nearly a billion gallons of drinking water a day—is one of very few water agencies to earn the Partnership for Safe Water’s most prestigious honor, the Excellence in Water Treatment Award. The SNWA’s River Mountains Water Treatment Facility earned the award in 2018, and its Alfred Merritt Smith Water Treatment Facility earned the award in 2019.
The Federal Safe Drinking Water Act sets water-quality standards for all water purveyors, in Nevada, these standards are enforced by the State of Nevada’s Bureau of Safe Drinking Water. Southern Nevada’s drinking water is carefully treated and regularly tested to ensure it meets these stringent requirements.

The LVVWD is a not-for-profit water agency that supplies water to more than 1.5 million people in Las Vegas and unincorporated areas of Clark County through a network of more than 6,800 miles of pipelines and service lines.
