Lead Testing and Removal questions, answered by experts

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.

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.

DIY lead testing kits are available, but they often lack the accuracy and reliability of professional services. Professional testing is recommended for more accurate results, as properly certified testers can provide a thorough analysis, clear recommendations, and the necessary legal documentation if remediation is required.

Properties should be tested for lead every 2-3 years, especially if they are older, have undergone renovations, or show deterioration of paint or interior finishes.

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.
