Southern Nevada Water Authority


The Southern Nevada Water Authority (SNWA) actively monitors for lead and copper in our drinking water supply.

The Environmental Protection Agency (EPA) has set an action level for lead at 15 parts per billion (ppb). According to the latest water quality analyses, levels of lead were detected at less than 1 ppb, well below levels that are determined to be a possible health concern.

Elevated levels of lead in drinking water can cause serious health problems, especially for pregnant women and young children. The presence of lead is primarily from materials and components associated with service lines and home plumbing. While SNWA is responsible for providing high-quality drinking water, we cannot control the variety of materials used in plumbing components.

If your faucets have gone unused for several hours, you can minimize the potential for lead exposure by flushing your tap for between 30 seconds to and two minutes before using water for drinking or cooking. If you are concerned about lead in your drinking water, you may consider having your water tested by a private laboratory.

Revisions made in 2007 to the EPA's Lead and Copper Rule include requirements for additional public education for these naturally occurring metals in drinking water. In 2010, the state of Nevada adopted these revisions.

This information is provided to help you assess risks in your tap water. For more information, call the EPA Safe Drinking Water Hotline at 800-426-4791, or read the EPA's information about lead in drinking water.
