Lead Testing and Removal questions, answered by experts

How you test for lead in your water depends on the source of your home's water supply. If you have municipal water, your local water system may offer to test the water for free or may connect you to a lab that will perform the testing.

If you have a private well that provides drinking water, you are responsible for testing it for lead. Look for a lab that is accredited by your state's Department of Environmental Protection to perform the test.

Lead testing prior to purchasing a property ensures that the new owners are informed about potential hazards, prevents health risks associated with lead poisoning, and facilitates timely remediation.

Professional testing for lead paint costs about $300, ranging from about $250 to $700, depending on the square footage, accessibility, and location. However, testing for lead paint with a DIY home-testing kit costs about $25, but doesn’t guarantee accurate results. The U.S. Environmental Protection Agency (EPA) recommends using a lead test kit that complies with the Lead Renovation, Repair, and Painting (RRP) Rule, which has strict criteria for ensuring a more accurate reading.

Common home surfaces to test for lead include:

  • Walls

  • Windows

  • Doors

  • Molding and trim

  • Railings

“Testing” can start with your senses: Assessing your water’s appearance, taste, and smell can all be good first steps. The best way to know for sure what’s going on with your water is to use a well water testing kit, which can tell you about the specific levels of bacteria, dissolved solids, and hardness of your water with precision. Have a pro test your well water at least once per year.

According to the EPA, there is no safe level of lead in the blood, and so the maximum contaminant level goal (MCLG) for lead in water is zero. Even at low levels, lead is harmful to human health. It can also remain in the body and build up over time with repeated exposure.
