Safe Drinking Water Act

Our water meets all SDWA standards.

The Las Vegas Valley's drinking water meets or exceeds all federal Safe Drinking Water Act standards. In fact, our water is tested more thoroughly and frequently than most bottled water.

The Safe Drinking Water Act (SDWA) was passed by Congress in 1974 and has been amended several times. The United States Environmental Protection Agency (EPA) writes the regulations to carry out the provisions of the act, which is administered through the State of Nevada.

The purpose of the Safe Drinking Water Act is to ensure that the drinking water supplied to the public is safe. EPA sets national drinking water standards that water system providers must follow.

Testing the Water

The State of Nevada Bureau of Safe Drinking Water oversees the state's public drinking water systems. The agency is responsible for making sure that all water purveyors follow the SDWA requirements. The U.S. EPA, in turn, monitors the state's drinking water program to ensure that the state is fulfilling its responsibilities.

The water supply is analyzed for:

  • Metals and other inorganic chemicals
  • Radiological constituents
  • Bacteria
  • Viruses
  • Protozoans (such as Cryptosporidium and Giardia)
  • Organic chemicals

Results of testing are available in the Water Quality Report and water analysis on that Web page. Also see the Source Water Assessments for SDWA assessments for Las Vegas Valley water systems.
