Do you know that chemicals in soil or groundwater can get into you indoor air? This is called vapor intrusion and needs for vapor intrusion investigation.

Sometimes substances that contain chemicals are leaked from a storage tank or spilled on the ground at a storage yard or factory.

Proper investigation is important as you cannot detect vapor intrusion by smell. This is due to solvents from commercial and industrial sites usually create an odor at low concentrations which unfortunately still pose a health risk.
