The Health Impact Evaluation Tool (HIET) is a website that helps residents of Louisville learn about air pollution in their area. It focuses on a type of pollution called Volatile Organic Compounds (VOCs), which can affect health. The tool uses data from EPA’s AirToxScreen to show current and historical estimated pollution levels for different neighborhoods.
