Exposure to lead can cause behavior problems and learning disabilities in young children and can also affect the health of adults.The United States Environmental Protection Agency (EPA) limits lead levels in your drinking water. For more than 20 years, Tucson Water has tested for lead in water from customer’s taps at homes to ensure it meets or exceeds EPA’s criteria. 

 

Sources of Lead and Minimizing Risks

High levels of lead and copper are not present in the groundwater or in the recharged Colorado River water that serve as our drinking water sources. The primary sources of lead in tap water are pipes and fixtures in individual homes where water can leach lead from the plumbing fixtures

To minimize the risks of exposure to lead:

  • Water temperature can affect the extent to which lead enters the water. Use water from the cold tap for making baby formula, drinking, and cooking.
  • Let the water run for a minimum of 30 seconds to two minutes if it hasn’t been turned on for six or more hours.

Lead Service Lines

Since 1999, Tucson Water has had a program to identify, remove, and replace lead service lines, the pipes that deliver water to meters from the main distribution line. In 2017, we launched "Get the Lead Out," a focused program to find and replace any remaining lead service lines by the end of 2018.

Results as of October 10, 2018:

  • Inspected 495 service lines in an area determined to be at risk of still having lead service lines present - click here for a map.
  • Removed 140 lead service lines and replaced with copper, the industry standard.

Monitoring for Lead and Copper

Tucson Water follows EPA's Lead and Copper Rule, a requirement for public drinking water systems. We monitor for lead and copper at over 100 locations on a regular basis, and report those results in our annual water quality reports

If you are concerned about lead in your water, you may wish to have your water tested. For a list of licensed labs in Arizona that can analyze your water for lead and copper, see ADHS’s Licensed Environmental Laboratories search page.
