Why should I attend?

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, large and multi-family buildings.

Learn the newest testing and mitigation techniques by exploring all 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.

Connect with your radon and vapor intrusion community in a personal way. Attending the symposium builds lasting friendships, and exposes professionals to the wider scope of radon and VI testing and mitigation specialists from around the world.
