Vapor Intrusion and Your Health

When groundwater or soil near hazardous waste sites become contaminated with certain chemicals, such as volatile organic compounds, vapors from the contaminants can move up into the air of nearby homes and businesses. This process is called vapor intrusion and can result in unexpected exposure to contaminants in indoor air. Vapor intrusion can be difficult to identify, so when residents learn that vapor intrusion is a problem in their homes or communities it can be quite distressing. In this podcast, we’ll hear how researchers are working to better characterize and predict vapor intrusion so they can help communities understand what it may mean for their health. We will also share tips for improving the air quality in your home.
