Lead Testing and Removal FAQs, answered by experts

Lead testing in residential properties involves collecting samples from paint, dust, soil, or plumbing and analyzing them in certified laboratories to accurately identify lead levels.

“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.

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.

Determining if your water main contains lead involves a few steps. First, check the age of your property, as homes built before the 1980s might have lead pipes. Contact your water utility company for information on your service line material. Then, you can hire a professional plumber to conduct an inspection or use a lead testing kit to analyze water from the main line.

Exterior paint contains a higher level of VOCs, which can be dangerous if you’re exposed to it for a long period of time. The good news is that paint’s toxicity reduces significantly once fully dried and cured. Do not keep open exterior paint cans in your home, basement, or garage, exposing your household to harmful chemicals over time.
