Lead Testing and Removal FAQs, answered by experts

Some causes of brown well water—like excess tannins or dissolved iron—don’t pose a health risk. In other cases, harmful bacteria might be the culprit. If your well water has suddenly turned brown, it’s a good idea to use a home water test kit to get a better sense of what’s going on with your water. Consider calling a professional for an expert opinion before drinking the water and hoping for the best.

Unfortunately, lead dust does not look different from any other type of dust. You cannot detect it with the naked eye. To determine if you have lead dust in your home, you will need to hire a local company to take a sample from the paint and test it for you in a lab.

Several different measurements may be used to determine the amount of lead in water. The most common unit of measurement is micrograms per liter (µg/L), which is the same as parts per billion. Another measurement is milligrams per liter (mg/L), which is the same as parts per million.

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

Lead removal is crucial in older homes to eliminate risks of lead poisoning, which can severely affect health, particularly in children, by impacting development and cognitive functions.
