Join us in #RockingOutRadon in Nashville

Indoor Environments 2023– The Radon and Vapor Intrusion Symposium (formerly AARST International Radon and Vapor Intrusion Symposium) is the largest gathering of specialists, educators, manufacturers, researchers, and technicians in the field of soil gas contaminants in the US. 2023 is AARST’s 37th annual conference, which continues to grow every year. We attract hundreds of attendees to come, learn, and network.

Stay current on all the ANSI/AARST national consensus standards utilized by numerous federal and state agencies, such as the Department of Housing and Urban Development (HUD) and the Environmental Protection Agency (EPA). The ANSI/AARST accredited standards include processes, procedures, and quality assurance systems to ensure standardized approaches for measurement and mitigation of soil gases in existing and new homes, schools, and large and multi-family buildings.

Learn the newest testing and mitigation techniques by exploring the latest products and technology. Deepen your knowledge in the industry by acquiring business-specific resources to elevate your business. Additionally, certified and licensed professionals can earn continuing education credits.

Indoor Environments 2023 boasts the largest soil gas exhibition hall featuring vendors from around the globe displaying the newest technology for soil gas testing and remediation, and agency partners specializing in communication and advocacy.
