Environmental health professionals play a critical role in land use and land reuse activities. In this hands-on session, participants will work with the Agency for Toxic Substances and Disease Registry (ATSDR) Land Reuse and Redevelopment Toolkit: An Environmental or Health Professional’s Guide to Creating Healthfields. The Toolkit integrates the ATSDR 5-step Land Reuse Model to Safely Reuse Land and Improve Health (5-step Land Reuse Model): 1. Engage with your development community; 2. Evaluate environmental and health risks; 3. Communicate environmental and health risks; 4. Redesign with health in mind; and 5. Measure success—evaluate environment and health change.
