About Lead in Drinking Water

What is Lead in Water?

According to the EPA, lead is a toxic metal that can dissolve into drinking water from older pipes, solder, and fixtures. It's invisible, tasteless, and odorless, making testing the only way to detect it. The EPA has set an action level of 15 ppb and states there is no safe level of lead exposure.

How to Reduce Exposure

  • Run water for 30 seconds to 2 minutes before drinking, especially in the morning
  • Use cold water for cooking and drinking (hot water dissolves more lead)
  • Install a NSF-certified filter designed to remove lead
  • Test your water, especially if your home was built before 1986
