The Environmental Protection Agency (EPA) is responsible for setting national drinking water standards that protect the health of more than 250 million people who get their drinking water from public water systems.

Since 1974, the EPA has set national standards for over 90 contaminants that may be found in drinking water. While the EPA and the State of Nevada set and enforce these standards, the City of Henderson is directly responsible for the quality of the water that flows to Henderson residents and businesses. The City's areas of responsibility include testing and treating the water, maintaining the distribution system that delivers water to your tap, and reporting on water quality to the State of Nevada, Division of Environmental Protection.

Water Quality Report

The purpose of the water quality report, also known as a consumer confidence report, is to provide consumers with information on what is in their drinking water and where that water comes from. The report helps consumers to make informed choices that may affect the health of themselves and their families, as well as understand the true costs and challenges of delivering safe drinking water.

The EPA sets forth strict guidelines for the content, format and distribution of the report and requires every public water system to deliver their water quality report to consumers by July 1 of each year. The report is based on calendar year data, collected between January 1 and December 31 of the previous calendar year.

Surface Water Source Assessment

The federal Safe Drinking Water Act, amended in 1996, requires states to develop and implement source water assessment programs to analyze existing and potential threats to the quality of public drinking water throughout the state.

A summary of the City of Henderson’s susceptibility to potential sources of contamination was initially provided by the State of Nevada in 2003 and was first included in the City of Henderson’s 2004 Water Quality Report. Information pertaining to the findings of the source water assessment are available below, or for viewing in person at the City of Henderson City Hall, 240 Water Street, Henderson 89015. Please call 702-267-2500 for an appointment.

Additional information about the Nevada Source Water Assessment Program may be found on the Nevada Division of Environmental Protection's website.

Las Vegas Wash

In 2007, several Southern Nevada water and wastewater agencies formed the Las Vegas Valley Watershed Advisory Committee (LVVWAC) in order to address laws that govern water management practices and to protect the valley's watershed.
