What is Soil Gas?
Soil contains air which tends to move around and sometimes comes out of the soil. If soil, or the ground water flowing through the soil, is contaminated by chemicals, they can easily turn into gas and contaminate the air contained within the soil. Once it contaminates the air in the soil, the contamination can travel with the air and find its way into buildings through cracks in the foundation. A simple venting system is typically used to alleviate the problem.
