What is Vapor Intrusion?

Vapor intrusion is a detriment to human health that threatens many U.S. properties

Disposal of harmful chemicals from dry cleaners and gas stations seeps into the ground and becomes a volatile organic compound over time.


The underground transportation of VOCs becomes a problem for neighboring homes, schools, workplaces, etc.

Vapor intrusion is a threat to many businesses and homes and will only increase in prevalence as the

irresponsible disposal of harmful chemicals continues
