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.

Public Notice for Extension

As part of the Safe Drinking Water Act, the Environmental Protection Agency revised the Disinfection Byproduct (DBP) Rule. Trihalomethanes (THMs) are governed by this rule, and the compliance date for the new calculation method for compliance is April 1, 2012. The City of Henderson believes that various factors about the source water (primarily lower Lake Mead water levels) and the distribution system may make it difficult to meet the revised regulation in some locations until planned system upgrades are complete. As allowed by federal law, the City of Henderson has requested a two- year extension for compliance with the new rule in order to complete construction of a third intake. The extension will begin April 1, 2012, and end March 31, 2014. To receive further information or to provide comment on the Public Notice for Extension, click here.

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. The report encourages consumers to consider the challenges and understand the true costs of delivering safe drinking water.

The EPA sets forth strict guidelines for the content, format and distribution of the report. The EPA 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.

The following links provide access to the water quality reports from the current and previous years. Contact the Public Information Office at (702) 267-2051 for reports from prior years.

Surface Water Source Assessment

The federal Safe Drinking Water Act was amended in 1996 and 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. The summary of this source water assessment was first included in the City of Henderson’s 2004 Water Quality Report. Information pertaining to the findings of the source water assessment is available here, 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.
