The Environmental Protection Agency’s Lead and Copper Rule requires public water providers to monitor the concentrations of these metals at customer taps, to ensure they are below prescribed limits.

The Department of Utility Services conducts a lead and copper testing program every three years on tap water samples collected from participating residences that meet the sampling criteria. The results of lead and copper testing have remained below the limits set by the Environmental Protection Agency since the Utility began its testing program.

The next lead and copper sampling and testing period will take place in the summer of 2025. Results from this sampling period will be available by November 2025 and included in the 2026 City of Henderson Water Quality Report.

The City of Henderson Department of Utility Services is offering a map to provide residents and property owners with information regarding their water service lines. The information provided is largely based on historical installation records supplemented, in some cases, by information acquired during physical inspections performed by the City. You can use the water service line map to see what service line information is available for your property.

To fulfill the requirements of the Environmental Protection Agency’s (EPA’s) Lead and Copper Rule Revisions, the City compiled an inventory of all water service lines, regardless of ownership. The compiled data was obtained by thorough review of installation records and construction and plumbing codes, physical site verifications (CCTV, meter box, and backflow inspections), and statistical analysis. The results of this effort proved that there were no lead service lines connected to our water distribution system and are reflected in this interactive map.

The City of Henderson public water system does not have pipes made with lead. There are a small percentage of homes built prior to 1989 that may contain lead solder in the private water service lateral that connects the public system to the home, or in the home’s plumbing fixtures.

In cases where private pipes, plumbing materials or plumbing fixtures contain lead, it may be possible for the metal to be leached out of the plumbing and into the drinking water due to the corrosive action of the water. Use of lead solder was banned from residential construction in 1989.

Southern Nevada residents enjoy some of the highest quality drinking water in the nation. Water quality varies across the country depending on the condition of the source water from which it is drawn and the treatment it receives.

Our community’s water comes from the Colorado River and it contains naturally occurring minerals that make it “hard” and less corrosive to piping materials. Additionally, a corrosion inhibitor called Zinc Orthophosphate is added to the water to help prevent metal that may be present in plumbing fixtures from leaching into the drinking water.

Residents concerned there may be lead in their home’s water can contact a laboratory to order a sample bottle and purchase a lead analysis for around $30-$50. The lab will provide instructions on how to collect a sample for lead and copper testing. For a list of labs certified to perform drinking water analyses, visit the Nevada Division of Environmental Protection website at Get Your Drinking Water Tested.

The City of Henderson does not test for lead in a home's water supply unless the residence is enrolled in the Copper and Lead Sampling program.
